Key Features

1. 01Operating 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.
2. 02Seal 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.
3. 03OTT 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.
4. 04Brand interchange numbers and fitment for this model are being confirmed — send your part number or drawing and OTT will check it before quoting.

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.
