Application

This heavy-duty bearing assembly is ideal for applications such as industrial gearboxes, crane sheaves, rolling mill equipment, and other machinery where load capacity and rotational accuracy are critical.

CO2 Impact

Choosing a remanufactured or new-old-stock bearing like this one avoids the production of a new unit, saving an estimated 19.0 kg of CO2. This is comparable to the emissions saved by driving a standard passenger car for 95 kilometers.

FAQ

What is the significance of the JHM522649-90N01 part number?

This is a set or assembly number from Timken. It indicates that all components, including two cones (JHM522649), two cups (JHM522610), and the necessary spacers, are supplied as a factory-matched set to ensure a specific internal clearance and precise mounting. It is critical to use all components from the same set and not mix them with others.

What type of lubrication is recommended for this TDI type bearing?

TDI (Tapered Double Inner) bearings like the JHM522649-90N01 are typically lubricated with either oil or grease, depending on the operational speed, load, and temperature of the application. For heavy-duty, low-to-moderate speed applications like industrial gearboxes, an ISO VG 220 or 320 gear oil or a high-quality EP2 grease is commonly used. Always consult your equipment’s maintenance manual for specific lubricant requirements.

Can I replace just one cone or cup from this assembly?

No, it is strongly advised against replacing individual components of a matched bearing set. The -90N01 suffix indicates a specific internal clearance has been set at the factory. Replacing a single cone, cup, or spacer will alter this preload/clearance, leading to premature bearing failure and potential damage to your equipment. The entire assembly should always be replaced as a single unit.
