PBL/SC-BF Direct Pneumatic Multi-Disc Brake

To make as easy as possible their application, two variants of these brakes are available, which differ from each other substantially from a point of view of construction and application, but both of them with the same technical characteristics. The first type (PBL-BF / SC) has to be keyed to a fixed shaft, to which is then freely mounted a cup housing: on one side, this cup housing is milled to anchoring the outer disks of the brake. The moving components to be braked are fixed on the other side. The second type (IBL y PBL-BF)has to be fixed to a wall and a milled hub has to be mounted on the rotating shaft; this hub is inserted into the fins of the inner disks. Both types have fixed cylinders with working pistons, the advantages of which are fully described in the introduction regarding static-cylinder clutches. For dry application (PBL-BF y PBL / SC-BF), a combination of bronze and steel brake disks is used. Para el modelo hidráulico, el tipo de aceite recomendado es el mismo recomendado para embragues. For the hydraulic model, the recommended type of oil is the same recommended for clutches.
