Modify - Hybrid Ceramic Ball Bearings 8mm (6pcs)

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)

Benefits of Hybrids Bearing Attributes

• Dissimilar Materials (Steel and silicon nitride)
• Less Wear
• Lower Operating Temperature
• Higher Speed
• Extended Bearing Life
• Lower Friction
• Stiffness
