Based on advanced bearing technology Ever-power tensioner and idler bearings possess met rigorous requirements from car manufactures like Hyundai Engine, Kia Motors, Volks Wagen and so on for several years. Our design concept is as follows.
Optimal materials selection for temperature use
Ideal sealing style to prevent grease leakage
Low torque engineering to reduce excessive seal friction
Grease selection for high temperature and extended use
Optimal clearance
Tolerance control to achieve correct alignment
Automatic defect detectors are installed along the way. Rigorous quality control enables us to focus on zero defect. We cover wide variety of car makers and models with more than 500 part amounts. Ever-power enjoys OE reputation 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 side.(Idler bearing at restricted side) There are numerous designs according to engine types.
Functions
· To supply belt with tension
· To transfer driving pressure from crankshaft
· To prevent belt slippage
· To prevent noise caused by off-line belt
· To minimize space of belt layout
Structure
Tensioner and idler bearing consists of basic parts like inner ring, outer ring, retainer, grease and seal. Pulley may be added to modify rotation ratio. Bracket could be added to adapt location for adding pressure. Races are among the bearing element parts. It offers grooved monitor for balls to locate. Outer race and inner competition make a set. Internal race is located on sub-assembly unit and outer race is defined on housing. Pulley could be added on outer race to supply timing belt program with designed revolution rate. Rolling component is “ball” operating between races. Retainer shifting along with balls separates person ball into placement. Also grease has essential role to reduce friction and 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 could be applied parallel to, as regarding a hydraulic bolt tensioner, or perpendicular to, as regarding a spring-loaded bike chain tensioner, the tension it creates. The force may be generated by a set displacement, as regarding an eccentric bicycle bottom level bracket ,which should be modified as parts put on, or by stretching or compressing a springtime ,as regarding a spring-loaded bicycle chain tensioner; by changing the quantity 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 functioning on a suspended mass, 
as regarding a chair lift cable tensioner. In the energy sector, the tensioner is a machine for preserving constant tension of the conductors during work of hanging the transmitting 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 reduction and harm 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 heat. Pulleys are usually manufactured from either plastic or steel, so verify the pulley itself for just about any damage as well. 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.
