The SHI 281 disc brake is a spring applied, hydraulically released, fixed caliper disc brake.

Advantages of this heavy-duty industrial caliper disc brake include its high torque output, fast response time, and ability to produce a range of torque values with its externally adjustable air-gap.

This hydraulic disc brake is primarily used as a safety brake in holding and e-stop applications. As a safety brake, it is designed for braking on the output shaft. When compared to a comparable floating caliper brake, fixed caliper brakes are ideal for applications where space constraints don’t present an issue. Fixed caliper brakes also provide the advantage of being able to go longer without adjustment.

Hindon provides comprehensive support for SHI models including repair services and full engineering and technical support.
