Rely on tested quality and order brake and work cylinders directly online.

Power transmission through compressed air

Brake and work cylinders are central components in compressed air systems – they convert air pressure into mechanical force and thus activate brakes or engine braking functions. A correctly dimensioned cylinder ensures reliable operation and prevents malfunctions in the brake circuit.

Robust components for high loads

The cylinders are designed for extreme loads in commercial vehicle operation. They work reliably under changing pressure conditions, guarantee constant braking force and help to ensure that the entire brake system remains stable even under continuous load or frequent use. Many models can also be serviced and overhauled using suitable repair kits.

Brake and Working Cylinders

What should you look out for when buying:

DRAFT RATIOS

The cylinder should exactly match your brake or payload in terms of diameter, stroke and lever travel.

TYPE OF APPLICATION

Note whether the cylinder must be designed for braking or additional functions (e.g. motor brake).

MOUNTABILITY

Check whether the cylinder can be mounted with existing brackets and whether repair or sealing kits are available to enable long-term maintenance.

Expert Guide: Everything You Need to Know About Brake and Actuator Cylinders

Brake and working cylinders are key components in compressed-air systems. They convert air pressure into mechanical force, thereby activating braking or auxiliary functions such as the engine brake. A properly functioning cylinder is essential for reliable performance in the braking circuit.

The brake cylinder generates the force for the actual braking, while the actuator cylinder activates additional functions—such as an engine brake or other pneumatically controlled actuating tasks. Both operate on the same principle but differ in their application and design.

Typical signs include audible air leakage, reduced or absent braking or steering response, a cylinder that does not fully release, and a drop in system pressure. Since braking safety is at risk, such symptoms should be checked immediately.

The diameter, stroke, and lever travel must be precisely matched to the brake and the payload. An incorrectly sized cylinder will generate insufficient or uneven force and may cause malfunctions in the braking system. Therefore, pay close attention to the correct force ratios.

Many models can be specifically maintained and overhauled using the appropriate repair and gasket kits, rather than being completely replaced. Before purchasing, check whether the cylinder can be mounted using the existing brackets and whether the appropriate repair kits are available.
