Extra Capacity Sealed Clean Four row Tapered Roller Bearing


NSK, the first company in the world to offer sealed roll neck bearings, now offers the Extra-Capacity Sealed-Clean series of roll neck bearings.


1. Newly designed internal specifications and a new compact seal result in a high-capacity design that provides increased bearing capacity.

2. The new main seal and seal holder are designed for easier mounting and dismounting.

3. The new bore seal prevents the buildup of negative pressure as a measure against water infiltration.

4. Bearing material is made from super-TF steel, which contributes to enhanced bearing life under conditions of contaminated lubrication.
