NU1006 Hybrid Cylindrical Roller Bearings have rings made of bearing steel and rollers made of bearing grade silicon nitride (ceramic). As ceramic rollers are lighter and have a higher modulus of elasticity and lower coefficient of thermal expansion than steel rollers, hybrid bearings can provide the following advantages:
Higher speed capability
Extend service life – by 4-8 times
Prevents the passage of electrical current
High resistance to contamination and corrosion
Extend grease life
Reduced wear
Low friction
