One Direction Clutch One Way Bearings (B205)

B205 One Direction Clutch One Way Bearings Type S200(B200) is a non bearing supported sprag type freewheel.Available size: S203(B203) , S204(B204),  S205(B205) , S206(B206) S207(B207) , S208(S208) ,  S209(B209),  S210(B210)The sprags run directly on the shaft provided by the user.Bearings are required to support axial and radial loads.Lubrication and sealing must also be provided by the installation. The preferred lubrication is oil.  When necessary grease lubrication is also possible.The housing bore to receive the outer race will be machined with a H7 tolerance.A key will transmit the torque. The shaft on which the sprags run must have a surface hardness of HRc 60 to 62 for a finished depth of 0, 6 mm minimum. Core hardness should be HRc 35 to 45. Surface roughness must not exceed 22 CLA.Maximum shaft taper 0, 01 mm per 50mm length. Concentricity between shaft and housing bore should be maintained within TIR 0, 05 mm.The design allows the use of most of the common lubricants used in power transmission including gear oils with EP additives.Catalogue of B205 one way bearing   TypeDrag torque(N.m) Overrunning Speed (r/min) Shaft size(mm) Outer race h7(mm) ThicknessKey way inner raceouter race(mm) (mm) B203 39.2240050016.5140  25  4.0×2.5 B204 58.8240050018.79647  25  5.0×3.0 B205 98180040023.62252  25  5.0×3.0 B206 235180035032.76662  28  7.0×4.0 B207 372180030042.08872  28  7.0×4.0 B208 549180020046.76180  32  10.0×4.5 B209 549120020046.76185  3210.0×4.5 B210 784120020056.10990  3210.0×4.5 B211 784120020056.109100  3210.0×4.5 B212 1230120018070.029110  42  10.0×4.5 B213 1230120018070.029120  4210.0×4.5 B214 1390100018079.356125  4212.0×4.5   Pictures /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
