Rolling mill bearing heater can substantially save the costs and improve the working efficiency.

JR-series of rolling mill bearing heaters are induction type bearing heaters newly developed for heating bearing inner sleeves by Beijing Renmin Bearing Factory after merging Beijing Bearing Research Institute. The development of these bearings has offset the deficiency of artificial disassembly and assembly of bearings.

Substantial cost savings: artificial disassembly and assembly of bearings in the past had to break the inner ring and easily damage bearings, but using a heater to disassemble the inner ring can keep the inner ring and the bearing intact and realize the reuse of the bearing. This can also save the electricity by 90%, oil by 100%, and the floor space of factories by 70%;
Working efficiency improvement: the shortest heating time is 30 seconds, which improves the working efficiency by 4 times and reduces 80% of operators;
Assembly quality improvement: well-distributed heating is conducive to improve the assembly quality;
Safe using height: putting an end to fire hazards;
Comply with the environmental protection requirement: without polluting the air by oil and gas, absolutely clean, conducive to environmental improvement and the health of workers.

Rolling mill bearing separate-installed machine

I. Usage:
This machine is applicable to the disassembly and assembly of 320, 350, 400, 450 and 550 mill roller boxes.

II. Functional characteristics:
The separate-installed machine can simultaneously assemble roller boxes onto both sides of the corresponding roller and simultaneously disassemble roller boxes from both sides of the roller. It can separately disassemble a roller box on one side of a roller according to the disassembly requirement.
