NU1004 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
