Aranlock lock washers are ideal for use as locking devices on shafts and tubes, etc. The lock washer has radial tabs with reinforcements on the edges, which increases the locking capacity and can be used on most materials, such as steel, metals or plastic.
In many cases, Aranlock can replace nuts, pins or other similar locking devices. Normally, no preparation of the shaft, such as grooves, is necessary, as the locking mechanism is very effective on its own. Fitting is simple and fast.
The washer sits firmly and can only be removed by being broken.
Compliant with DIN 6796, our tensioning washers are robustly dimensioned and designed for use in medium or high load screw joints. The high spring force affords effective protection against relaxation and creep when joints are exposed to high stresses and movements resulting from thermal expansion or contraction. In such instances, tensioning washers replace conventional lock washers.
Tensioning washers can be stacked in series and/or parallel. Used like disc springs. Series stacking increases the available deflection of the spring stack and parallel stacking increases the force. The desired installation is as near flat as possible. Spring force as below.
If required, untreated spring washers can also be supplied direct from the factory. Spring washers in custom sizes and special materials, e.g. stainless, acid proof, phosphor bronze or Nimonic 90, can be produced upon request.

Wave spring washers have a restricted spring capacity and are primarily used to eliminate axial play, e.g. against a bearing. Dy 4.65–7.75 mm has two waves, others have three.
Diameter dimensions quoted are in mm and with the washer flat.
Dy = Outer diameter
Di = Inner diameter
Lo = Unloaded length t = Thickness
L1 = Loaded length
Fn = Spring force in Newtons at L1
