Perfection High Speed Bearing Update

We have heard your feedback about our PPS bearings and have discontinued them. The PPS bearings (white cages) did not perform up to the high quality standards we and our customers demand. They have been replaced with bearings using PAEK (black cages) or in some cases phenolic for the cage material.  

PAEK is a stronger cage material than PPS and more resistant to chemical intrusion. They handle being in poor maintenance conditions and resist sterilization better than the PPS material. PAEK cages are black and are shown as such in our bearing images and cross section views. Most Perfection bearings feature the black PAEK cage though a limited selection will have orange phenolic cages.

Below is a diagram showing the approximate bearing cage colors and more can be learned at Tech Central >
