GT20060 tensioner pulley bearing

Tensioner Bearings are critical components in various mechanical systems, particularly in automotive engines and industrial machinery. They maintain proper tension in belts or chains, ensuring smooth operation, reducing vibrations, and preventing slippage or misalignment.

Functions of Tensioner Bearings:

Maintain Belt/Chain Tension – Prevents slack, ensuring efficient power transmission.

Reduce Vibrations & Noise – Absorbs shocks and dampens oscillations.

Extend Belt/Chain Life – Minimizes wear by preventing excessive friction.

Ensure Proper Alignment – Keeps belts/chains correctly positioned on pulleys/sprockets.

Common Types:

Automatic Tensioner Bearings – Use springs or hydraulic mechanisms to self-adjust tension.

Manual Tensioners – Require periodic adjustment by a technician.

Idler Pulley Tensioners – Incorporate a bearing-mounted pulley to guide and tension the belt.

Applications:

Automotive Engines – Timing belts, serpentine belts.

Industrial Machinery – Conveyor belts, power transmission systems.

Agricultural Equipment – Combines, tractors.
