With technological advancements, a wide variety of specialized pipe-bending machines have entered the market, injecting new vitality into the industry. Today, the experts at Huameng Machinery discuss how to address the issue of bearing overheating in fully automatic pipe-bending machines:

① Excessive or insufficient grease in the bearing;
② Poor quality or contaminated grease;
③ Improper fit between the bearing and the shaft journal or end cap (too loose or too tight);
④ Eccentric bearing bore causing friction against the shaft;
⑤ Misaligned motor end cap or bearing cap;
⑥ Misaligned coupling between the motor and the load, or overly tight drive belt;
⑦ Excessive or insufficient bearing clearance;
⑧ Bent motor shaft.

2. Troubleshooting
① Apply grease according to specifications (fill 1/3 to 2/3 of the volume);
② Replace with clean grease;
③ Repair loose fits with adhesive; for tight fits, machine or grind the shaft journal or end cap bore to achieve the correct fit;
④ Repair the bearing cap to eliminate friction points;
⑤ Reassemble the components;
⑥ Realign the coupling and adjust belt tension;
⑦ Replace with a new bearing;
⑧ Straighten the motor shaft or replace the rotor.
