Bessey GCS-NCB Portable Cone Bearing Heater 120V

Product Description

The BESSEY GCS-NCB is a portable cone-style bearing heater designed for heating bearings prior to installation on shafts or into housings. Built from aluminum, the unit accepts bearings with inside diameters ranging from 3/8 inch to 8-1/4 inches (9.5 to 210 mm). It operates on 120 volts and draws up to 15 amps, with a maximum operating temperature of 250 degrees F. The cone design allows even heat transfer to the bearing race, expanding the bore for a clean slip-fit during assembly. Mechanical technicians, millwrights, and maintenance professionals use this tool in industrial and commercial maintenance settings.

The GCS-NCB is suited for bearing installation work across a wide range of applications, including electric motor rebuilding, pump assembly, conveyor maintenance, and general industrial equipment repair. Its portable format makes it practical for field service work as well as shop use. The unit accommodates both inch and metric bearings within its stated inside diameter range, reducing the need for multiple heaters on a mixed-fastener job site.

Compatibility

Designed for use with bearings having an inside diameter between 3/8 inch and 8-1/4 inches, covering metric sizes from 9.5 to 210 mm. Suitable for ball, roller, and sleeve bearings within this bore range.

Installation Notes

This unit is typically used by millwrights, machinists, or mechanical maintenance technicians. Before use, ensure the bearing is clean and free of lubricant that could degrade under heat. Do not exceed the 250 degrees F maximum operating temperature, as overheating can alter bearing hardness and tolerances. Always use insulated gloves when handling heated bearings, and follow the bearing manufacturer's guidelines for target installation temperature.
