Sapphire Hybrid Bearing 3x10x4mm, Dry Lubricated

Product code: DSBB-3-10-4

Silicon nitride hybrid bearings are excellent for UHV applications. They are high-performance super-precision ball bearings for rough applications. The main advantages are:

Higher Accuracy Ceramic balls have a smoother finish than steel, vibration and spindle deflection is reduced allowing higher speeds.

Less Friction, Less Heat Ceramic Hybrid Ball Bearings truly are “anti-friction". Lower friction leads to less wear, less lubrication and extends life.

Reduced Lubrication Requirements Ceramic Hybrids sport improved kinematic behavior, generate less friction and demand less lubrication.

Low Thermal Expansion A low thermal expansion coefficient allows hybrids with ceramic balls to undergo smaller changes in contact angle reducing preload variations improving life and maintaining tolerances.

Non-Conductive Electrical pitting and fluting of the raceway is caused when current passes through the ball to the raceway, typical in electric motor applications, ceramic balls insulate.

Extended Operating Life With their numerous advantages ceramic hybrid ball bearings typically yield 5 to 10 times longer life than conventional steel-steel ball bearings in most applications.
