| Spec. | Applies electroless nickel plating on a bushing. (Antirusting treatment is applied to screws.) [ ! ] Electroless nickel plating decreases bushing's allowable torque by 20 to 30%. BMC: Not RoHS Compliant (Screw: SCM435 Dacrotized Treatment) BMR: RoHS Compliant (Screw: SCM435 GeoMet Coating) [NG] Combination with OP is not available | Pulleys will be shipped with bushings uninstalled. | Lowers the flange by cutting. FC: 0.5 mm Increments [ ! ] No surface treatment is applied on flange circumference. | The product is shipped without swaging the flange. (Flange Included) | The product is shipped by swaging the flanges either on the bushing side (LFC) or the opposite side (RFC). (Flange 1 pc. Included) | |
