Materials
Rings & Balls
Gcr15 high carbon chromium bearing steel is the standard material for precision bearing rings and balls.

Retainers
The retainer is normally made of H62 copper sheet or 08F cold rolled steel belt, however, in cases of corrosive environment, misalignment, or high speed operation, stainless steel, nylon, or phenolic resins can be used upon request.

Shields & Seals
Shields are made of steel as standard, and the optional AISI-300 stainless is available, when required.
Buna Nitryl is the standard material used for the seals. Fluorocarbon, silicone, and Teflon seals are available for high temperature applications, upon request.

Rust Resistance
Under normal operating conditions, the rust resisting period is six months. After this period, the product should be checked and rust protected again if necessary, so as to prevent rust from occurring.

Packing
Generally the bearings are packed into plastic pipes or small boxes and then packed into a carton. If required, special packaging can be accommodated and must be specified prior to order.
