TORQUE RESISTANT FLANGED BALL BUSHINGS:
PDF Catalogue of Linear Bearings
 |
The Torque-Resistant Flanged Ball Bushings have the same basic boundary dimensions as the cylindrical bushings. Optimisation of the wall section and ball diameters allows for precise mating of the bushings to shafts. Shaft diameters 6, 8 & 10mm have a cut away flange. Use with Torque Resistant Spline Shafts. Sizes up to 25mm are also available in stainless steel, SPF4-5.. (where .. is the shaft diameter). |
