Bearings Products: Metal-Polymer Bearing Retainer
Composite metal-polymer bearing
retainers made from silver-coated
polyamide-imide feature precision
machining to keep tolerances on cage
diameter, ball-pocket location, and
piloting-land interface under 0.002 in.
The retainer withstands repeated
autoclave cycles and speeds up to
500,000 rpm.
The silver layer is slightly porous to
hold more lubricant while the silver
itself provides a self-lubricating wear
layer and an extra layer of protection
against microbial infection. The metal
and polymer layers resist reaction with
moisture or harsh chemicals.
