YRT 50 High Precision Rotary table bearing detail Specifications
Material:52100 Chrome Steel Structure:Axial & Radial Trust Bearing Type:Rotary Table Bearing Precision Rating: P4/P2 Construction:double direction, for screw mounting Limiting speed:440 rpm Packing :Industrial packing and single box packing Weight:1.6KgMain Dimensions Inner diameter(d):50mm(Tolerance: 0/-0.008) Outer diameter(D):126mm(Tolerance: 0/-0.011) Width(H): 30mm(Tolerance: 0/-0.125) H1:20mm C:10mm Diameter of inner ring for design of adjacent construction(D1):105mm Fixing holes in inner ring(J):63mm Fixing holes in outer ring(J1):116mm Radial & axial runout:2 μm Basic dynamic load rating, axial(Ca):56KN Basic static load rating, axial(C0a):280KN Dynamic load ratings,radial(Cr): 28.5KN Static load ratings,radial (Cor): 49.5KNYRT bearings (rotary table bearings) 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. Feature of Rotary Table Bearing 1. High axial and radial load capacity. 2. High tilted rigidity:YRT series bearings are with preload and high precision:Precision at P4, P2. 3. Radially and axially preloaded after fitting. 4. High load capacity: Bearings can support axial load, radial load and tilting load. 5.High speed: YRTS series bearings can be applied in the high speed working condition.
