The SKF TMBR heating ring is an aluminum tool for mounting inner rings of cylindrical roller bearings using induction heating. It fits over the ring, induces current, and expands the ring uniformly without impact or excessive force. This method protects the raceway and simplifies shaft fitting, making it a practical choice for maintenance shops.

The designation TMBR NJ…EC breaks down as follows: TMBR is the SKF family of heating rings for mounting. NJ indicates suitability for cylindrical roller bearings of the NJ series, which have a removable inner ring. EC denotes the stamped steel cage variant common in that series. For example, TMBR NJ2320EC matches an NJ 2320 EC bearing. For other sizes, the numeric suffix changes and the ring must correspond to the bearing.

In maintenance of equipment with cylindrical roller bearings—such as gearboxes, reducers, pumps, fans, paper machines, steel mills, and cement plants—these rings are used when the fit is interference and hammering or pressing is undesirable. Heating only the inner ring achieves the necessary expansion for effortless sliding, and the ring becomes fixed as it cools. Repair shops handling large bearings also rely on this method.

To select the ring, consider the inner ring diameter of the bearing and the power of the induction equipment. The TMBR rests on the ring and should cover it uniformly. During mounting, monitor temperature to avoid exceeding the bearing's limit; even heating prevents distortion. Proper lubrication and alignment after mounting are essential for service life. Follow the manufacturer's instructions for heating time and handling.

Heating rings from different manufacturers are not interchangeable because design and power are matched to their own bearings. If replacement is needed, identify the exact bearing (e.g., NJ 2320 EC) and select the corresponding accessory. At MR Industrial Accessories, we supply SKF brand and can guide you with the bearing code to ensure the correct ring.
