They incorporate single-, double-, and multiple-row designs differing in arrangement, design, and construction of the retaining flanges. Available bore sizes range in diameter from 0.9843 to 39.3701". Cage materials include molded glass fiber-reinforced polyamide or optional machined brass and pressed steel.
