Double Row Tapered Roller Bearing(Inch Series)of Vista's bearing products. Vista's products will give you perfect experience.

Features and benefits:

Long service life 

The crowned raceway profiles of basic design bearings and the logarithmic raceway profiles of Vista Explorer bearings optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends, and reduce the sensitivity to misalignment and shaft deflection compared with conventional straight raceway profiles. 

Enhanced operational reliability 

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

Consistency of roller profiles and sizes 

The rollers incorporated in Vista double row tapered roller bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution, reduces noise and vibration, and enables preload to be set more accurately.
