Having your Belts and Chain tensioned correctly is very important if you want to get the best life out of your drive. We carry a large range of chain and belt tensioning Japanese products. With an extensive line of tensioners, you can count on UMS Transmissions to supply premium quality belt tensioners for your power transmission system. We ensure that every tensioner we supply is built to rigid tolerances and specifications that guarantee fit, form and function for your application. Comprehensive line includes parts to fit cars, vans, SUVs, and light trucks. Full line coverage for imported, domestic, and heavy-duty cars, trucks, and vehicle applications. For these belt tensioners, there’s no such thing as a too-heavy application. An Auto Tensioner is a device for maintaining the constant tension necessary for power transmission of accessory drive system with load variation under harsh engine conditions. By using an auto tensioner, it controls poor transmission from decline in tension, slip, squeal (noise). Difficult tension management maintenance becomes unnecessary.




Belt tensioners are extremely important in the proper operation of the accessory belt drive system. A tensioner maintains the correct amount of tension on the belt at all times throughout its duty cycle. It also helps protect other components such as the alternator and water pump from undue stress and premature failure. In addition, a tensioner is a relatively inexpensive part to replace. So, every time you replace a multi-ribbed belt, be sure to replace the tensioner at the same time. Furthermore, when a tensioner has reached the end of its service life, we recommend that all parts are replaced at the same time to ensure the best long-term solution.
