Product Details

3M™ Silicon Nitride HS Rollers excel in high-stress environments where traditional metal rollers fail due to galling and contact fatigue. Our silicon nitride HS rollers are also 60% lighter than steel and typically reduce problems common to metal versions.

Manufactured to Withstand Punishing Treatment in Engines. 3M™ Silicon Nitride HS Rollers withstand the high contact stresses of valve train applications in heavy-duty diesel and gasoline engines. 3M™ Silicon Nitride HS Rollers are used as part of rocker arm or roller lifter assemblies, which are subjected to increasing stress levels because of the higher fuel pressures used in today’s heavy-duty engines. Made of extremely durable, wear-resistant 3M™ Silicon Nitride, our HS rollers deliver high performance where traditional metal rollers fail due to galling and contact fatigue.
