They can also be used as stops. After the clamping process, the contact surfaces of clamping pads auto- matically reset themselves to their initial position. This prevents the bea- ring from jamming in an inclined position when the workpiece is inserted. The bearing can be rotated by a maximum of 9° and is secured against further rotation. see also... • Clamping Pads GN 709.7 (with Internal Thread) → Page 1132 Information • GN 709.2 Steel Tempered, phosphated - - Ball steel Hardened, blank - - Spring element plastic (PUR) (Type BR / RR) • GN 709.25 Stainless steel AISI 431 Tempered - - Ball stainless steel AISI 420C Nickel plated - - Spring element plastic (PUR) (Type BR) • ISO Fundamental Tolerances → Page 2151 • Elastomer Characteristics → Page 2158 • Stainless Steel Characteristics → Page 2166 • RoHS Specification • Serrated hard metal ball On request 2 Type B Smooth contact face R * Serrated contact face BR Smooth contact face, with automatic return RR * Serrated contact face, with automatic return 1 d 1 n6 d 2 d 3 d 4 Ball- Ø d 5 H7 Location bore l 1 ±0,02 l 2 ±0,1 l 3 max. t min. for maximal static load Static load max. in kN Type B Type BR Type R Type RR Type B / R Type BR / RR Type B / R Type BR / RR 12 M 3 7,2 10 12 11 17 11 17 3,2 3,2 6 12 10 18 M 4 10,5 16 18 17 23 17 23 4,0 4,0 8 14 25 28 M 5 20   25 28 25 34 25 34 5,5 6,0 13 22 90
