DESCRIPTION
Silicon Nitride Ceramic balls are over 100% harder than steel balls. In a hybrid bearing, the extremely hard and smooth Ceramic Ball keeps raceways clear of contaminants by pushing them away from the contact patch. In addition, the Ceramic ball remains extremely smooth, preventing ball to race damage. For the end user, this means reduced bearing wear and longer bearing life at high precision.
Vickers Hardness 10 KG Load
Ceramic = 1550
Steel = 730
Lower Operating Temperature results from Ceramic's
lighter weight (lower frictional losses)
higher stiffness (lower contact area with metal race reducing friction)
inertness (no adhesive wear or heat generation from micro-welding)
lower thermal expansion (stable pre-load & contact angle reducing friction)
