Enhanced operational reliability

Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.

Improved wear resistance

In particular, these are made of extremely clean and homogenous steel and undergo a unique heat treatment, which improve the resistance to wear.

Improved sealing performance four-row tapered roller Bearings with less leakage and less frictional heat

The optimized seal design ensures high protection against external contamination but keeps friction and frictional heat low.

This seal design also provides a better NSK as2 Bearing retention of lubricant, minimizes environmental impact and reduces maintenance costs. Equal load carrying capacity for sealed and open bearings

The optimized and compact seal design enables identical internal design.

Total bearing interchangeability Bearings with and without intermediate rings as well as open and sealed bearings are available with identical external dimensions.

This allows total bearing interchangeability of current standard design bearings with those without intermediate rings and/or with optimized seal design.
