Tensioner & Idler Bearing
Based on advanced bearing technology Ever-power tensioner and idler bearings have fulfilled rigorous requirements from car manufactures like Hyundai Electric motor, Kia Motors, Volks Wagen and so on for several years. Our design idea is as follows.
Optimal materials selection for high temperature use
Ideal sealing design to prevent grease leakage
Low torque engineering to reduce excessive seal friction
Grease selection for 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 range of car makers and versions with more than 500 part numbers. Ever-power enjoys OE status 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 pressure from crankshaft
· To avoid belt slippage
· To prevent noise caused by off-line belt
· To reduce space of belt layout
Structure
Tensioner and idler bearing consists of basic components like inner ring, outer ring, retainer, grease and seal. Pulley may be added to modify rotation ratio. Bracket may be added to change location for adding pressure. Races are among the bearing element parts. It has grooved track for balls to find. Outer race and internal competition make a set. Inner race is situated on sub-assembly device 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” running between races. Retainer moving along with balls separates individual ball into position. Also grease has important role to reduce friction and essential oil seal serves to hold grease and shut foreign 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 in the case of 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 must be modified as parts put on, or by stretching or compressing a spring , as in the case of a spring-loaded bicycle chain tensioner; by changing the quantity of a gas, as regarding a marine riser tensioner; by hydraulic pressure, as in the case of a hydraulic bolt tensioner; or by gravity functioning on a suspended mass, as regarding a seat lift cable tensioner. In the energy sector, the is usually a machine for keeping constant pressure 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 while the tensioner maintains pressure against it. A failing tensioner pulley could cause power reduction 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 metal, so examine the pulley itself for any damage aswell. For Auto parts, we’ve tensioner pulleys designed for many vehicle versions. Check out our options and find a tensioner pulley for your car, truck, or SUV.
