3M™ Silicon Nitride Cylindrical Roller Components offer high compressive strength, contact fatigue resistance, electrical resistivity, and a low coefficient of friction in hybrid and ceramic bearings. Designed to operate at lower noise levels than steel counterparts, these components run at higher speeds with reduced friction, all while resisting abrasion — unlike coated and uncoated metal. These properties make them an effective alternative to larger steel bearings in certain high-stress applications, including racecar gearboxes and machine tool spindles.
3M™ Silicon Nitride Cylindrical Roller Components exhibit high tribological compatibility, meaning they experience reduced friction when in contact with either cast iron or steel. This allows them to operate at higher speeds and stress levels with less lubrication than metal rollers.
