Technical data

Specifications

Applications

• Bearing insert for injection-molded belt pulleys

Key Features

1. 01Performance: Designed for grease retention, high-temperature operation and high-speed rotation in automotive belt tensioner pulleys.
2. 02Supply: Supplied as a bearing insert for B2B customers that manufacture belt tensioner pulleys and assemblies. Select by bearing number, mounting dimensions and construction.
3. 03Operating conditions and options: Designed for high-temperature, high-speed operation with low running noise. Grease can be selected to suit the operating conditions. NBR (nitrile rubber) is the standard seal material, with ACM (acrylic rubber) available on request. The standard nylon cage is BASF PA66. BASF PA46 is available as an order-specific option. Confirm the final grease, seal material and cage specification when ordering.
4. 04Seal contact and torque options: Where offered for the bearing model, OTT RS light-contact seals provide lower seal drag, while OTT RSM medium-contact seals provide higher seal drag. Both designs are intended to retain grease. Select the seal contact level to suit the required torque and operating conditions.
5. 05OTT qualification criterion: The bearing must complete a 500-hour endurance test under simulated operating conditions, with no observed lubricant leakage (grease or oil) and no abnormal running noise.
6. 06Temperature validation: OTT automotive belt tensioner bearings have passed high- and low-temperature testing under simulated operating conditions.

Packaging

Available in OTT branded packaging or custom OEM packaging. Individual bearings are sealed in PE bags, packed in branded carton boxes, then palletized in wooden crates for export shipping.
