Tensioner & Idler Bearing
Predicated on advanced bearing technology Ever-power tensioner and idler bearings have fulfilled rigorous requirements from car manufactures like Hyundai Engine, Kia Motors, Volks Wagen and so forth for many years. Our design idea is as follows.
Optimal materials selection for temperature use
Ideal sealing design to prevent grease leakage
Low torque engineering to lessen excessive seal friction
Grease selection for high temperature and extended use
Optimal clearance
Tolerance control to attain correct alignment
Automatic defect detectors are installed along the way. Rigorous quality control enables us to target zero defect. We cover wide selection of car makers and models with more than 500 part quantities. Ever-power enjoys OE reputation in global aftermarket.
Functions of Tensioner & Idler Bearing
Tensioner bearing
Belt driven outer ring mechanism is inherent in this style. Tensioner bearing is positioned at slack side.(Idler bearing at limited side) There are many styles according to engine types.
Functions
· To supply belt with tension
· To transfer driving force from crankshaft
· To avoid belt slippage
· To prevent noise due to off-line belt
· To minimize space of belt layout
Structure
Tensioner and idler bearing consists of basic components like inner ring, external ring, retainer, grease and seal. Pulley may be added to modify rotation ratio. Bracket may be added to modify location for adding pressure. Races are among the bearing element parts. It provides grooved track for balls to find. Outer race and internal competition make a set. Internal race is located on sub-assembly unit and outer competition is set on housing. Pulley may be added on external race to supply timing belt program with designed revolution rate. Rolling element is “ball” operating between races. Retainer moving along with balls separates individual ball into position. Also grease has essential role to reduce friction and essential oil seal serves to carry grease and shut international particles from intrusion.

A tensioner is a device that applies a force to create or maintain tension . The force may be applied parallel to, as regarding a hydraulic bolt tensioner, or perpendicular to, as regarding a spring-loaded bike chain tensioner, the strain it creates. The force may be generated by a set displacement, as in the case of an eccentric bicycle bottom bracket , which should be altered as parts wear, or by stretching or compressing a spring , as in the case of a spring-loaded bike chain tensioner; by changing the volume of a gas, as regarding a marine riser tensioner; by hydraulic pressure, as regarding a hydraulic bolt tensioner; or by gravity acting on a suspended mass, as regarding a chair lift cable tensioner. In the power sector, the is a machine for keeping constant tension of the conductors during work of hanging the transmission network.

A tensioner pulley manuals the belt around the tensioner and allows the belt to spin as the tensioner maintains pressure against it. A failing tensioner pulley could cause power loss and harm to your belt-powered systems. You might have a failing tensioner pulley if you hear any squeaking or squealing under the hood. Bearings on the pulley can wear out, causing noise and high temperature. Pulleys are usually manufactured from either plastic or steel, so check the pulley itself for any damage aswell. For Auto parts, we’ve tensioner pulleys available for many vehicle versions. Have a look at our options and find a tensioner pulley for your vehicle, truck, or SUV.
