Tensioners and Idlers.pdf
Based on advanced bearing technology Ever-power tensioner and idler bearings have got met rigorous requirements from car manufactures like Hyundai Engine, Kia Motors, Volks Wagen and so on for several years. Our design idea is as follows.
Optimal materials selection for temperature use
Ideal sealing style 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 achieve correct alignment
Automatic defect detectors are installed in the process. 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.
Features of Tensioner & Idler Bearing
Tensioner bearing
Belt driven outer ring mechanism is inherent in this style. Tensioner bearing is placed at slack side.(Idler bearing at limited side) There are various designs according to engine types.
Functions
· To provide belt with tension
· To transfer driving force from crankshaft
· To prevent belt slippage
· To prevent noise caused by off-line belt
· To reduce space of belt layout
Structure
Tensioner and idler bearing contains basic elements like inner ring, outer band, retainer, grease and seal. Pulley could be added to adapt rotation ratio. Bracket may be added to adjust location for adding stress. Races are one of the bearing element parts. It offers grooved track for balls to find. Outer race and internal race make a set. Internal race is located on sub-assembly unit and outer race is defined on housing. Pulley may be added on external race to supply timing belt system with designed revolution rate. Rolling component is “ball” running between races. Retainer moving along with balls separates individual ball into placement. Also grease has essential role to reduce friction and essential oil seal serves to hold grease and shut international particles from intrusion.

A tensioner is a device that applies a force to create or maintain stress 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 generates. The force could be generated by a fixed displacement, as in the case of an eccentric bicycle bottom bracket ,which should be adjusted as parts use, or by stretching or compressing a spring ,as regarding a spring-loaded bicycle 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 functioning on a suspended mass, as in the case of a chair lift cable tensioner. In the power sector, the tensioner is a machine for maintaining constant stress of the conductors during work of hanging the transmission network.

A tensioner pulley guides 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 damage to your belt-driven systems. You might have a failing tensioner pulley if you hear any squeaking or squealing under the hood. Bearings on the pulley can degrade, causing noise and temperature. Pulleys are usually made of either plastic or metal, so examine the pulley itself for any damage as well. For Auto parts, we have 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 leading manufacturer of Original Tools (OE) idler pulleys. Ever-power Idler Pulleys satisfy or exceed OE specifications. High quality, high power bearings run cooler and go longer than original bearings. Ever-power Idler Pulleys are built to last by resisting dirt, salt, and other under-hood contaminants. Designed for use on automobiles and light trucks as locked center tensioning, automatic belt tensioning and idler pulleys.
Additional hardware incorporated with the majority of idler pulleys to create installation easier.
