YRT1030 China YRT Table Bearings Factory HONB 1030*1300*145mm
The YRT1030 bearing is a YRT Rotary table bearing with an inner diameter of 1030 mm , an outer diameter of 1300 mm, a width of 145 mm. It typically uses P4/P2 grade precision tolerances and features a Brass cage/Plastic cage cage, Bearing steel Gcr15 rings. It primarily bears Axial and radial directions, Its dynamic radial rated load is approximately 1380KN, its static radial rated load is approximately 12000KN. It uses Negative clearance standard radial clearance, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Feature: High load/High precision/High rigidity
Application: Applied on the machine tools, milling heads, rotary tables
YRT basic rotary table Bearings are designed with a radial full roller, two groups of axial needle Roller, cage assembly, an out ring, a L-section Inner ring and the second ring. the out ring and inner ring have fixing holes. Added preload after fitting simplified the unit construction,Shorten the work of fixing, Lowered the high on fixing. so this kind of bearing is particularly suitable for the situatin of High precision, high stiffness and the Union loads with low speed such as index tables and revolving milling heads.See Fig
