Heating rings for cost-effective bearing
changes
A new range of aluminium heat rings are a practical solution for regular dismounting of cylindrical roller bearings.
When flangeless inner rings of cylindrical roller bearings, or those with only one flange have to be removed infrequently, or if larger sizes of inner ring have to be dismounted, it is less costly to use heating rings such as the TMBR series The rings are available as standard for the following bearing sizes: 204 to 252, 304 to 340, 406 to 430.The inside diameter of the ring is the same as the raceway diameter of the inner ring and it is machined to tolerance Z9
The ring is heated using a hot plate or naked flame to approximately 280C and then placed over the inner ring and clamped using the handles.
To ensure satisfactory heat transfer from the ring, the inner ring should first be coated with a viscous oil which is resistant to oxidation.
