Heating rings are suitable for dismounting the inner rings of cylindrical roller and needle roller bearings without ribs and inner rings with one rib. Heating rings are particularly advantageous for the occasional extraction of small and medium-sized bearing rings (bore diameter 50 to 200 mm). Depending on the size of the ring, heating takes between 5 and 30 seconds. The heating rings are made from light metal. They have a radial slot. They are easy to handle due to the

heat-insulated handles.

Heating rings are heated to between 200 and 300 °C by means of an electric heating plate. The cylindrical outside surface of the bearing inner ring must be coated with a silicone-free heat conducting paste (HEATING-RING.PASTE). This gives optimum heat transfer. The heating ring is then slid over the inner ring to be extracted.

The bearing ring must be removed from the heating ring immediately after extraction in order to prevent overheating. Each bearing size requires a specific heating ring. By agreement, we can supply these heating rings made from a special aluminium alloy.

In order to prepare a quotation, we require the following information: 

1. Bearing designation or ring dimensions
2. Drawing of mounting position stating fits
3. Approximate number of parts to be extracted per day
