Hot Sell YRT1200 Bearings With High Quality Competitive Price 1200*1490*164mm
The YRT1200 bearing is a YRT Rotary table bearing with an inner diameter of 1200 mm , an outer diameter of 1490 mm, a width of 164 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 745KN, its static radial rated load is approximately 2800KN. 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
*this kind of Bearing have axial and radial running precision for your chosen.
