Clamp collar double-split steel C45 black oxide finished bore 15mm with bolts DIN 912 12.9 type B1
Material: Steel C45, black oxide finish. Screw steel 12.9. Typ B1: With two axial mounting bores.Typ B2: With two axial mounting bores, with sunk holes for cylindrical cap screws DIN 912.The thread of the screw DIN 912 is covered with a layer of nylon.Tolerance b: +0.08mm / -0.25mm. Temperature range: -40ºC to +175ºC. * Fitting screw size for B1.** Fitting screw size for B2. Features: does not damage the shaft, stronger clamping force than with set collars, even distribution of clamping forces, easy readjustment, precision honed bores. Remarks to collars from steel: The black oxide on the clamping collars is formulated as part of the total performance of the product.It enhances the holding ability of the collar, it efficiently reduces slipping on the shaft, has anti-stick-slip characteristics and helps to keep the torque rating of the screw within its designed parameters. The oxide layer also provides corrosion protection.
