About SUNTES
SUNTES is the power control brand of the Sanyo group in Japan. Sanyo Shoji handles product sales, while Sanyo Kogyo develops, designs and manufactures the equipment. The group specializes in controlling mechanical power: transmitting movement, stopping rotation, holding equipment in position and responding to overload conditions.
The product range extends from individual disc brakes and replacement pads to hydraulic pressure generators, centrifugal clutches, torque releasers and load-testing equipment. Choosing a product starts with the function required by the machine and continues with the exact operating conditions and installation interfaces.

How to Select a SUNTES Product
First define whether the application requires stopping, holding, controlled engagement, speed-dependent braking, overload release or load measurement. Then establish the torque, rotational speed, operating duty, heat load and available control source. For a brake assembly, confirm disc geometry and mounting clearances. For a hydraulic circuit, check pressure, required fluid volume, fluid compatibility and every connection interface.
Preserve the full model code and suffix when comparing products or ordering replacements. Similar base codes can have different release methods, fluid requirements, electrical specifications or mechanical interfaces. Use the dimensions and ratings for the exact configuration described in the linked article.
Product Enquiries
For assistance identifying a SUNTES product, provide the complete model number, quantity, nameplate photographs, installation drawings and operating conditions. For maintenance parts, include the parent brake or clamper model and photographs of the existing component. This information helps establish which configuration and interfaces need to be checked.
