1 Hydraulic Caliper Disc Brakes SF Series SF SF 40 SF 30 SF 1 SF SF Brake torque in knm PINTSCH BUBENZER is certified according to DIN EN ISO 01: Brake disc diameter in mm Reliable High Performance Robust Design Easy Maintenance B1s

2 Description SF Main Features - Steel Mill Execution Two identical caliper halves, ready for operation, with spring packs set to nominal force and limit switch for release control (heat resistant) Up to mm airgap between linings and brake disc Easy, manual pad wear compensation Organic, non-asbestos linings Special seals for flame-proof liquids Viton seals Options Heat resistant wiring of limit switches Limit switch wear control (special execution) Heat resistant piping Completely piped supports for one or more calipers Hydraulic power units Cleaning pad pplications Hydraulic power unit - Steel Mill Execution Dead man s circuit Stainless steel tank Non flammable oil Oil temperature switch utomatic emergency release system Stainless steel cover The high capacity of these brakes makes them particularly suitable as secondary emergency brakes on main hoists (ladle cranes) Other applications are possible in material hand ling, requiring power and compact design in either direction of rotation, particularly in replacing band brakes Use of the brakes for applications with high duty cycles should be specifically indicated during technical selection procedure Operating Restrictions Brakes of this range are tested both mechanically and hydraulically and are set to nominal force. This setting can only be changed by the manufacturer. Operating conditions other than described in this brochure require the manufacturer s approval and may influence the function of the caliper and its components Please Note We supply a detailed operating manual with every order. Nevertheless, we would point out that brakes are only as safe as the servicing and maintenance performed while they are in operation. The guarantee for the correct functioning of our brakes is therefore only valid if the user adheres to the German DIN standard 1434 part (drum and disc brakes, servicing and maintenance in operation), or to comparable standards in his own country. PINTSCH BUBENZER Service This includes the verification of the brake selection, if required. detailed questionnaire is provided for this purpose. Installation and commissioning on site is possible by PINTSCH BUBENZER service engineers. Drawings as DWG/DXF files for your engineering department are available upon request. Bs

6 Piping Samples Disc brakes SF and BSC Rev Example: Piping of one brake unit one hydraulic power unit Equal Tee Distributor Brake Power Unit Pipe Example: Piping of two brake units - one hydraulic power unit Equal Tee Distributor Pipe Brake Equal Tee Power Unit N ttention: For operating two brake units with one power unit please note, that the power unit should be installed between the brakes in the centre to achieve almost equal pipe length on both sides (equal apply time of brakes).
