four-row tapered roller Bearings
Contact NowEnhanced 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 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 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.
