CAGES
In general, SKONN cages are pressed steel ribbon cages & pressed steel snap cages. For extra-high speed application, synthetic-resin, stainless steel, nylons(Phenolic resins) will be used upon request.
SHIELDS & SEALS
SPCC is the main material for SKONN shields, and carbon steel & stainless steel can be used upon request. Buna Nitrile is standard sealing material we use, while fluorocarbon, 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.
