Product Description

A bearing with a simple shape in which cylindrical rollers and a raceway are in linear contact.
[Features]
·Large load capacity primarily for receiving radial loads.
·The friction between the rolling elements and the flange of bearing ring is small making it ideal for high-speed rotation.
·Various options can be selected according to applications, such as flange on both inner and outer races, no flange, separable type, and axial load bearable.
[Application]
·For machine tools, motors, pumps, etc.

Features

●As the roller and the orbital plane are in line contact, it is a bearing that load capacity of the radial load is large.

Specification

●Seal: None
●Precision Grade: JIS B 1514 0 Grade
●Working Temperature Range: -25 to 120°C

Materials

●High Carbon Chromium Steel Bearing

: 30; 60; 90
