INA Idler Pulley

INA Idler Pulley

A small part with a lot of responsibility

Product description:

For many years, major car and engine manufacturers have trusted INA belt drive components. High-quality INA Idler Pulleys are selected by them in both timing drive and front-end accessory drive (FEAD) systems.

Idler pulleys have to meet the same requirements for service life and noise development as tensioners. They are used to calm critical belt sections, to avoid collision problems with surrounding components, to guide the belt or to increase the angle of belt-wrap on neighboring pulleys.

High-precision, single-row ball bearings with an increased grease reservoir have proven to be effective here. If needed, double-row angular contact ball bearings, also with an optimized grease reservoir, can be used. Depending on requirements, these bearings are individually tuned, have high-temperature roller-bearing greases and the appropriate seals made of plastic or steel.

INA Idler Pulleys – the highest quality means long-term performance of timing drive and FEAD.
