CAGES
In general, HF or CRC cages are pressed steel ribbon cages & pressed steel snap cages. For extra-high speed application, synthetic-resin, stainless steel, nylons will be used upon request. |
SHIELDS & SEALS
SPCC is the main material for HF or CRC shields, and carbon steel & stainless steel can be used upon request.
Buna Nitrile is standard sealing material we use, while fluorocabon, silicone, and teflon seals are commonly specified for high temperatures. |
LUBRICATION
Different types of greases can be supplied for shielded & sealed bearings and oil for open bearings.
