QCB THERMOPLASTIC HOUSINGS
QCB bearing housings are made of PBT high-grade glass-filled
thermoplastic polyester and are completely interchangeable with
conventional cast-iron housings, resulting in a maintenance free housing
with excellent mechanical strength, stiffness and dimensional stability that
will never rust or corrode.
Developed for use where high standards of cleanliness are important or a
significant amount of liquid is present such as in the food and beverage
industries. The smooth housing surfaces are much more hygienic that
equivalent cast-iron units whose rough surfaces can harbour objectionable
dirt, mould and bacteria.
NO PLATING OR COATING TO CHIP OR PEEL
Coated or plated cast-iron housings can scratch, chip and peel. The very
act of installation can damage the finish to be removed around the edges
of the bolts. Because QBC Thermoplastic housings are solid PBT,
coatings are not required for protection. And even if they are scratched or
chipped there is no vulnerable cast-iron to be exposed.
QCB THERMOPLASTIC HOUSINGS ARE DURABLE
With a tensile strength of 17 300 psi, and the ability to be pressure
washed with hot water, QCB Thermoplastic housings will stand up to the
toughest applications.
ALL OTHER PARTS STAINLESS STEEL
To maximise corrosion resistance, not only is the bearing completely
stainless, but so are the bolt inserts and grease nipples! Inserts are filled
with a high-quality food-grade (FDA Approved) grease.
USED IN MANY INDUSTRIES
Because of their corrosion resistant and non-magnetic properties, QCB
Thermoplastic housings find application in a wide variety of industries
including food processing; canning; bottling; pharmaceutical; chemical
processing and other general industrial applications.
A COMPLETE RANGE
QCB Thermoplastic bearings are available in a wide range of styles and
sizes, with inch, metric or even plastic inserts. Snap-on through or closedend covers as well as back seals complete the range.
