RÖHM the specialist in clamping and automation technology is the exclusive representation of Gamet Bearings in Germany.

Gamet Bearings have been manufacturing high precision tapered roller bearings for over forty years in their Colchester factory.

Originally founded to serve the machine tool industry, Gamet has today expanded into other sectors of industry having high precision bearing requirements. These include the coating of materials, photographic emulsions or adhesives, and the printing and packaging industries.

Bearings should remain in the original packaging for as long as possible prior to fitting to prevent the risk of contamination. Whenever possible, bearings should be mounted onto the shaft in vertical position. It is very important that the correct method of mounting is chosen and that suitable equipment is used.
The inner races (cones) of the bearings must be pre-heated to expand sufficiently to assist mounting on shaft. Never attempt to fit cold as the amount of interference between cones and shaft will prevent sliding and any direct blows will cause damage to rolling elements and raceways. Heating can be achieved using induction heaters, ideal for grease lubricated bearings, or oil baths suitable for oil lubricated bearings. Under no circumstances should a pre-greased bearing be heated by submersing in oil as contamination of grease will occur. The temperature required to sufficiently expand cones to allow reasonable mounting time varies depending upon size and section, but 70°C will suffice for
the majority of applications. Care must be taken when locking bearings to ensure all rolling elements are seated properly, this is achieved by rotating at periodic intervals during locking.
