Cage material

Material for cages is required to have properties of good wear resistance, dimensional stability and good mechanical strength for perfect bearing running purpose. Therefore, for selection of cage material, it is important to consider the operation conditions. 

● Stamping steel cages
These light weight cages have relatively high strength and can be surface treated to further reduce friction and wear. Cold-rolled steel is used for pressed cages.

● Nylon cages
 

Nylon cage is applied depending on the type of bearing and the application, but should not be used at temperatures above 120 ℃ or below -40℃. For the majority of injection moulded cages, Nylon 66 is used. This material, with glass fibre reinforcement or without, is characterized by a favourable combination of strength and elasticity.
