Sanyo Kogyo Suntes DB-3012A4-01 Industrial Brake

The Sanyo Kogyo Suntes DB-3012A4-01 Industrial Brake is a pneumatic disc brake designed for heavy‑duty industrial machinery, delivering reliable braking force via compressed air. The DB‑3012A‑4‑01 variant is described as a Pneumatic Applied Spring Release model, combining pneumatic actuation with a spring return for release. Key specs include an operating air pressure range of 0.03 to 0.70 MPa, disc outer diameter compatible from 200 mm up to larger sizes, and a disc thickness of 10 to 10.4 mm. The pad type is DB‑0433, with a documented pad wear allowance of 7 mm, and the braking assembly weighs about 6.0 kg; lever ratio is 0.75, influencing the actuation torque. Friction characteristics after break‑in are dynamic around 0.30 (0.38 with wear) and static around 0.15 (0.30 with wear), providing predictable braking across typical industrial loads. This brake is part of Suntes’ pneumatic disc brake family and is suited for machines requiring adjustable braking force and straightforward mounting on standard disc configurations.
