Custom CNC Machined PEEK Bearing Cage | Large Diameter Thin Section Retainer

Custom CNC Machined PEEK Bearing Cages

Suntron manufactures precision CNC machined PEEK bearing cages for high-performance bearing systems. Compared with conventional metal cages, PEEK cages offer lower weight, reduced friction, superior chemical resistance, and excellent dimensional stability.

The lightweight structure makes PEEK an ideal material for high-speed applications where performance, reliability, and service life are critical.

The bearing cage shown features a large diameter thin-section design with:

• ID: 180 mm
• OD: 186 mm
• Thickness: 5 mm

Custom dimensions and pocket configurations are available upon request.
