YRTM260 260×385×55mm YRTM Axial/radial Bearing With Measurement System
The YRTM260 bearing is a YRT Bearing with an inner diameter of 260 mm , an outer diameter of 385 mm, a width of 55 mm. It typically uses P4 grade precision tolerances and Gcr15 balls, Gcr15 rings. It primarily bears Radial, Its dynamic radial rated load is approximately 7.1, its static radial rated load is approximately 5.83. It uses C0 standard radial clearance, Rubber. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Feature: cylindrical
Application: Rotary table

Axial radial bearings YRT are axial and radial combined cylindrical roller bearings, including two thrust needle roller bearings and a radial cylindrical roller bearing with the combination of axial and radial preload, For the convenience of transportation and fixing, two or three symmetrical screws are fastened to the two rings in order to prevent rollers and rings generating collisions which influence bearing accuracy.
Axial/radial bearing YRTM: Bearing of YRTM series correspond in the double direction thrust cylindrical roller combined bearing YRT but are additionally fitted with a steel ruler, to control and adjust thedouble direction thrust cylindrical roller
bearing rotation accuracy, and guarantee the machine high precision operation.
