The SKF TMBR heating ring is an aluminum tool used to mount inner rings of cylindrical roller bearings. It is placed around the ring and heated to expand it, so it fits without impacts or excessive force. It is a practical solution for maintenance workshops that need to mount bearings safely and repeatably. MR Accesorios Industriales carries this line as part of its mounting tool offering.
The TMBR NJ… designation identifies the heating ring model and the bearing size it was designed for. In the examples TMBR NJ412, TMBR NJ418 and TMBR NJ419, the final number indicates the corresponding bearing of the NJ series. Each ring is sized for a specific inner ring diameter, so it is important to verify that the part number matches the bearing to be mounted. If you have any doubts, send us the bearing part number and we will confirm the right ring.
These rings are used in mounting cylindrical roller bearings of the NJ series, which have a removable inner ring. They are common in industries such as metallurgy, cement, mining and paper, where large bearings are frequently mounted. They are also used in railway maintenance workshops and in power generation plants. In Argentina, MR Accesorios Industriales carries them to serve these applications.
To select the correct ring, take into account the inner ring diameter of the bearing and the type of fit. Heating must be uniform and controlled: excessive temperature can alter the properties of the steel. Follow the manufacturer's recommendations for the maximum heating temperature. Also, verify that the ring is clean and free of deformation before use. Careful mounting extends bearing life and prevents damage to the shaft.
SKF TMBR heating rings are specific to SKF bearings of the NJ series, but they may be compatible with bearings from other manufacturers that share the same dimensions. It is always advisable to confirm interchangeability by consulting equivalence tables or the supplier. At MR Accesorios Industriales we can advise you on compatibility with other brands, without compromising the integrity of the mounting.
If you need a heating ring for your application, send us the bearing or ring part number by WhatsApp. At MR Accesorios Industriales we will quote you promptly and help you choose the right tool. We carry the SKF brand as part of our mounting and maintenance tool line.
