INA Tensioner Pulley with/ without Grooves

Constant belt tension – in all driving conditions

Product description:

Major car and engine manufacturers have trusted INA belt-drive components for many years. High-quality INA tensioners are selected by them in both timing drive and front-end accessory drive (FEAD) systems.

Especially in interference systems like timing drives, a constant tension on the timing belt is essential to prevent the belt from slipping and causing major damage to the engine. For this, high-precision, single-row ball bearings with an increased grease reservoir have proven to be effective. If needed, double-row angular contact ball bearings, also with an optimized grease reservoir, can be used. All bearings and tensioner systems are precision-tuned to meet corresponding requirements and outfitted with high-temperature roller-bearing greases and the appropriate seals. Depending on requirements, these bearings have pulleys made of plastic or steel.

The mechanical and automated tensioners from INA ensure constant belt tension in all conditions and during frequent load changes in everyday driving – which guarantees dependable timing drive performance.
