Product Description

A roller bearing with an inner race featuring a two-row raceway groove, an outer race featuring a spherical raceway, and barrel-shaped rolling elements.
[Features]
·The raceway center of the outer race coincides with the center of the bearing. Has a self-aligning property.
·It is capable to operate despite a tilting of the inner race and outer race caused by installation error to the housing or deflection of the shaft.
[Application]
·Areas where it is difficult to center the shaft and housing.
·Such as transmission shaft and other areas prone to shaft deflection.
·Where large axial loads can be applied.
·Steel equipment, paper manufacturing machines, mining machines, etc.
·Ideal for applications subject to radial loads, axial loads in both directions, and their combined loads.

Features

●The radial load, the axial load in both directions, and the capacity to load these combined loads are getting bigger.

Specification

●SPQ（piece）:1
●Seal: None
●Precision Grade: JIS B 1514 0 Grade
●Working Temperature Range: -25 to 120°C

Materials

●High Carbon Chromium Steel Bearing
