YRT260 Slewing Bearings 260*385*55mm
The YRT260 bearing is a YRT Rotary table bearing with an inner diameter of 260 mm , an outer diameter of 385 mm, a width of 55 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 93, its static radial rated load is approximately 290. 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
Company introduction
Hongyuan bearing is specialized at producing YRT Rotary table bearings and Crossed roller bearings since year 2005. Our main products are YRT series rotary table bearings and crossed roller bearings,with precision of P5,P4,or P2, which outer ring diameter ranges between Ø50mm-Ø1800mm.Our rotary table bearings cover YRT basis series, YRTS high rotational speed axial radial bearings, YRTM rotary bearing with angle measuring system,and ZKLDF double direction axial angular contact ball bearings. Our crossed roller bearings cover RB series, RE series, RU series, RA SERIES, CRBH series, SX series, XR series crossed taper roller bearings. With Hongyuan’s talented staff and modernized management system, the company is qualified by ISO9001:2015 Certification. Most of our facilities and high precision machines are imported from Germany or adjusted by ourselves. 50% of productions are for export market in Europe, North America and others, the YRT bearing from hongyuan has 70% marketing share in China.
YRT axial and radial bearings introductions
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.
*this kind of Bearing have axial and radial running precision for your chosen.
Bearing characteristics:
1. High precision: P4 precision, P2 precision
2. High rigidity: This series bearing have preload
3. High load:This series bearing can bear double-direction axial load, radial load and tilting moment
