Installation tips for
maximum bearing operation
1.
Handle with care. Never pound directly on a bearing or ring. If a
bearing is dropped, it is best not to install it. Store bearings horizontally in a dry
place in their original unopened package and never place bearings on a dirty
surface; periodically turn over sealed and shielded bearings to prevent grease
from settling to one side.
2.
Inspect the shaft and housing. Check for size and damage; remove
nicks and burrs with emery paper, and wipe clean with a soft cloth. Replace or
repair shafts and housings showing obvious signs of wear or damage. A shaft
placed in a vise for mounting should be protected from vise jaws with a sheet of
soft metal.
3.
Avoid overheating. During heat-mounting operations, never bring a
flame in direct contact with the bearing and never heat beyond 230°F. Also,
immediately hold a heat-mounted bearing in place against the shaft shoulder
until it cools and locks in place. Otherwise, the bearing may creep away from
the proper position.
4.
Use identical replacement bearings. Replacement bearings should be
identical to the bearings they replace. Contact an SKF Authorized Distributor or
SKF for interchange information.
5.
Use the right tool for the job. Induction heaters, oil injection kits, and
hydraulic nuts are among the specialized tools available for mounting and
dismounting bearings over 4 in. O.D. Their use lowers the possibility of
damaging bearings and speeds the process.
6.
Pay attention to the bearing’s press fit. Use a press for any bearing
under 4 in. O.D. Pressure should be applied only to the bearing ring with the
press fit, which is usually the ring that rotates after the bearing is installed.
Pressure to the ring without the press fit will damage the raceways.
2
7.
Don’t wash new bearings. Bearing manufacturers take great care to
package and ship bearings that are dirt-free and ready for lubrication. There’s
usually no need to wash them or remove the protective slushing compound.
8.
Proper lube is critical. Bearing manufacturers evaluate several factors
before determining the type of lubricant required for specific bearings. Be sure
to follow their recommendations. Temperature and contamination conditions
will influence the frequency of lubrication changes.
9.
Rotate idle bearings. Bearings installed in equipment that is subject to
vibration while the shafts are stationary may incur false brinelling damage,
which also occurs when equipment is not properly protected during shipment.
It can appear as bright, polished depressions on the inner and/or outer races,
as well as on the rolling elements.
10.
Look for danger signs. Keep alert for three sure signs of improper
bearing operation: excessive noise and increases in vibration and temperature.
Troubleshooting instruments like hand-held vibration pens, digital
thermometers, and electronic stethoscopes help spot bearings in poor
operating condition.
11.
Find the cause of bearing failures. Bearings are built to last, so
frequent failures may point to an installation or lubrication problem. SKF
bearing analysis experts can identify the cause of bearing failure and help you
prevent it in the future.
12.
The contact between the bearing ring and a properly machined and
dimensioned bearing seat should not require the use of bonding agents to
prevent movement or turning.

Speed ratings
There is a speed limit to which rolling bearings can be operated. Generally, it is
the operating temperature that can be permitted with respect to the lubricant
being used or to the material of the bearing components that sets the limit. The
speed at which this limiting bearing temperature is reached depends on the
frictional heat generated in the bearing (including any externally applied heat)
and the amount of heat that can be transported away from the bearing.
Bearing type and size, internal design, load, lubrication and cooling conditions
as well as cage design, accuracy and internal clearance all play a part in determining speed capability. In the accompanying tables two speeds are listed:
(Thermal) Reference Speed and (Kinematic) Limiting Speed.
Warning: The new Reference and Limiting Speeds are not to be used as a
direct substitution for the previous Oil and Grease speed ratings. Consult SKF
to determine the actual reference speed limit for your operating conditions.
Reference speeds
The reference speed for a given bearing represents the permissible operating
speed of said bearing when subjected to the specific operating conditions of
load, lubrication type and method as outlined in ISO 15312. This standard has
been established for oil lubrication but is also valid for grease and uses the following reference conditions:
• A temperature increase of 90° F (50° C) above an ambient temperature of
68° F (20° C), (thus a bearing temperature of 158° F (70° C), measured on
the bearing stationary outer ring or housing washer.
• Radial bearing: a constant radial load, being 5% of the basic static load rating Co.
• Thrust bearing: a constant axial load, being 2% of the basic static load rating Co.
• Open bearings with Normal clearance.
For oil lubricated bearings:
• Lubricant: mineral oil without EP-additives having a kinematic viscosity at
158° F (70° C) of: v = 12 mm2/s (ISO VG32) for radial bearings, and
v = 24 mm2/s (ISO VG68) for thrust roller bearings
• Oil bath with the oil reaching up to the middle of the rolling element in the
lowest position.
For grease lubricated bearings:
• Regular lithium soap grease with mineral base oil having a viscosity of 100 to
200 mm2/s at 104° F (40° C) (e.g. ISO VG 150).
• Filling approximately 30% of the free space in the bearing.
The reference speed will be reached after 10 to 20 hours running time. Under
these specific conditions the reference speed for oil and grease lubrication will
be equal.
4
Speeds above the reference speed
It is possible to operate bearings at speeds above the reference speed if the
bearing friction can be reduced, for example by lubrication systems with small,
accurately measured quantities of lubricant or when heat can be removed
from the bearing by circulating oil lubrication with cooling of the oil, by cooling
ribs on the housing, or by directed cooling air streams.
Any increase in speed above the reference speed without taking any of
these precautions would only cause bearing temperature to rise excessively.
An increase of bearing temperature means that lubricant viscosity is lowered and film formation is made more difficult, leading to even higher friction and further temperature increases. If, at the same time, the operational
clearance in the bearing is reduced because of increased inner ring temperature, the final consequence would be bearing seizure.
Limiting speeds
The speed limit is determined by criteria that include: the stability and or
strength of the cage, lubrication of cage guiding surfaces, centrifugal and gyratory forces acting on the rolling elements, and other speed-limiting factors.
Experience gained from laboratory tests and practical applications indicates
that there are maximum speeds that should not be exceeded for technical reasons or because of the very high costs involved.
Limiting Speeds shown in the tables are based on the demands of high speed
running applications and are valid only for the specific design and cage design
shown in the tables. It is possible to run bearings faster than the limiting
speeds, but several factors must be reviewed and improved such as the running accuracy, cage material, lubrication, heat dissipation and design of the
bearing. It is therefore advisable to contact SKF Applications Engineering for
advice. For enclosed and open bearings using grease lubrication, additional
parameters have to be considered such as lubrication of cage guiding surfaces
and the shear strength of the lubricant, which is determined by the base oil
and thickener.
Open balls bearings with low friction typically have Reference Speeds greater
than the Limiting Speed. In these cases the permissible speed must be calculated from the operating conditions and the lower value between the permissible and Limiting speed used.

Note: Minimum radial loads are necessary for satisfactory rolling bearing operation.
This is particularly true for roller bearings running at high speeds, where inertia forces
and friction from the lubricant may cause damaging sliding –rather than
rolling–movements between the rollers and raceways.

Note: The relubrication intervals shown are based on a good quality lithium based
grease at a maximum temperature of 160°F. Reduce the interval by half for each
27°F above 160°F, or for vertical applications. (High temperature greases, like
polyurea, can operate for longer periods of time than those listed above.) Lubricate
more often in applications where there is a risk of heavy solid and chemical
contamination. Consult manufacturer or SKF application engineering for details.
LGHP 2 ball and roller bearing grease
LGHP 2 is a polyurea-based grease designed for use in electric motors. Unlike
many polyurea-based greases, which are inherently noisy during operation,
LGHP 2 meets strict SKF noise requirements. Each batch is blended and
selected for consistency and adherence to quietness standards. The grease is
also recommended for applications where long life is required.
With LGHP 2, users can often avoid compatibility problems when
relubricating bearings. LGHP 2 is the factory fill grease used in SKF
bearings under the designation GXN.

Prolong your life
The life of your electric motors—
with INSOCOAT® bearings from SKF®.
Conventional motor bearings get “fried” by
the electrical current passing through them.
The result is premature failure and high
maintenance costs. The SKF® solution is
INSOCOAT® inverter-duty bearings that
require no rework prior to mounting.
These drop-in replacement bearings feature
a coating of aluminum oxide on the inner or
outer ring, providing an insulating barrier
which prevents electrical current from
causing microscopic “melting” of the bearing.
In addition, INSOCOAT bearings are treated
with a sealant that resists humid
environments, heat and chemicals.
INSOCOAT bearings are 100% performance
tested to 1,000 V DC with a minimum ohmic
resistance of 50 MΩ and available for shaft
diameters up to 155 mm.
