Tensioner & Idler Bearing
Based on advanced bearing technology Ever-power tensioner and idler bearings have got fulfilled rigorous requirements from car manufactures like Hyundai Electric motor, Kia Motors, Volks Wagen and so forth for several years. Our design idea is as follows.
Optimal materials selection for temperature use
Ideal sealing design to avoid grease leakage
Low torque engineering to lessen 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 allows us to target zero defect. We cover wide variety of car makers and models with more than 500 part quantities. 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 placed at slack aspect.(Idler bearing at restricted side) There are many styles according to engine types.
Functions
· To supply belt with tension
· To transfer driving push from crankshaft
· To prevent belt slippage
· To prevent noise due to off-line belt
· To reduce space of belt layout
Structure
Tensioner and idler bearing contains basic parts like inner ring, external ring, retainer, grease and seal. Pulley could be added to adapt rotation ratio. Bracket could be added to adjust location for adding tension. Races are among the bearing element parts. It offers grooved track for balls to locate. Outer race and inner competition 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 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 important role to reduce friction and 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 pressure . The force could be used 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 generates. The force could be generated by a set displacement, as in the case of an eccentric bicycle bottom bracket , which must be modified as parts wear, or by stretching or compressing a spring , as in the case of 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 regarding a hydraulic bolt tensioner; or by gravity functioning on a suspended mass, as in the case of a chair lift cable tensioner. In the energy sector, the is usually a machine for 
keeping constant tension of the conductors during function 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 can cause power loss and damage to your belt-driven systems. You might have a failing tensioner pulley in the event that you hear any squeaking or squealing under the hood. Bearings on the pulley can degrade, causing noise and temperature. Pulleys are usually manufactured from either plastic or metal, so examine the pulley itself for just about any damage aswell. For Auto parts, we’ve tensioner pulleys available for many vehicle models. Have a look at our options and look for a tensioner pulley for your car, truck, or SUV.
