Tensioner & Idler Bearing
Based on advanced bearing technology Ever-power tensioner and idler bearings have fulfilled rigorous requirements from car manufactures like Hyundai Motor, Kia Motors, Volks Wagen and so on for several years. Our design concept 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 focus on zero defect. We cover wide selection of car makers and models with more than 500 part numbers. Ever-power enjoys OE popularity in global aftermarket.
Functions of Tensioner & Idler Bearing
Tensioner bearing
Belt driven outer band system is inherent in this design. Tensioner bearing is positioned at slack side.(Idler bearing at limited side) There are many styles according to engine types.
Functions
· To provide 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 includes basic components like inner ring, outer band, retainer, grease and seal. Pulley may be added to modify rotation ratio. Bracket may be added to modify location for adding stress. Races are one of the bearing element parts. It has grooved track for balls to locate. Outer race and inner race make a set. Inner race is situated on sub-assembly unit and outer race is defined on housing. Pulley could be added on outer race to provide timing belt system with designed revolution price. Rolling element is “ball” working between races. Retainer shifting along with balls separates person ball into position. Also grease has important role to lessen friction and essential oil seal serves to carry 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 bicycle chain tensioner, the strain it creates. The force may be generated by a fixed displacement, as in the case of an eccentric bicycle bottom bracket , which must be modified as parts 
wear, or by stretching or compressing a springtime , as regarding a spring-loaded bicycle chain tensioner; by changing the volume of a gas, as in the case of a marine riser tensioner; by hydraulic pressure, as in the case of a hydraulic bolt tensioner; or by gravity acting on a suspended mass, as in the case of a seat lift cable tensioner. In the power sector, the is usually a machine for preserving constant stress of the conductors during work of hanging the tranny 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 loss and harm to your belt-driven systems. You may 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 warmth. Pulleys are usually made of either plastic or steel, so examine the pulley itself for just about any damage aswell. For Auto parts, we’ve tensioner pulleys designed for many vehicle models. Check out our options and look for a tensioner pulley for your vehicle, truck, or SUV.
Ever-power is a respected manufacturer of Original Products (OE) idler pulleys. Ever-power Idler Pulleys meet or exceed OE specs. High quality, high power bearings operate cooler and go longer than primary bearings. Ever-power Idler Pulleys are built to last by resisting dirt, salt, and various other under-hood contaminants.
