FAQs

The tensioner plays a crucial role in maintaining the proper amount of tension in the belt to ensure synchronous drive. Incorrect tension, whether too loose or too tight, can lead to severe engine failure. Tensioners are available with either manual or automatic adjustment options.

There is no recommended timeframe in which to replace your tensioner, especially as the belt itself usually needs replacing before the tensioner does. However, you should inspect your tensioner each time you service your car to monitor its condition and replace it if necessary.

Standard tensioners typically operate at a maximum pressure of 1500 bar.

Our standard tensioners are specifically designed to fit most commonly used ANSI B 16.5, 16.47, and API flanges.

Standard tensioners are ideal for a wide range of applications. However, for situations with limited space or exceptionally high load requirements, custom-built tensioners might be necessary.

Standard tensioners are well-suited for various bolting projects involving standard flange sizes in industries like: Oil & Gas, Chemical Processing, Power Generation, Shipbuilding, General Construction.

While standard tensioners offer a good range of compatibility, they might not fit every unique flange configuration. An adaptor set (optional) might provide some versatility, but for highly customized needs, custom-built tensioners are the best option.

A tensioner is a device that applies a force to create or maintain tension. The force may be applied parallel to, as in the case of a hydraulic bolt tensioner, or perpendicular to, as in the case of a spring-loaded bicycle chain tensioner, the tension it creates.

Here's how it works: Spring Force: The spring mechanism in the tensioner generates a consistent force. This force is applied to the tensioner arm, which in turn presses the pulley against the belt. The tensioner arm is designed to move, allowing the pulley to adjust its position and maintain the desired tension.

On circular flanges, the recommended use is of at least four Hydraulic Stud Tensioners and, preferably, 25% or 50% cover. For example, on a flange with 36 studs, use four, nine (25% cover), or eighteen (50% cover) Hydraulic Stud Tensioners. For accuracy and speed, some applications require 100% “cover”.
