Gearbox Preheating Processing: First 100-Hour Operation
This guide focuses on reducer preheating, temperature monitoring, and first oil change. The initial 100-hour performance directly determines long-term reliability. New reducers require no-load and half-load runs in the first 10 hours to smooth metal surfaces. A 50°F temperature rise in the first hour is normal, but continuous rise after 2 hours indicates faults. Oil change intervals vary: worm gear reducers at 24 hours, planetary reducers at 50–100 hours, and gear reducers at 100 hours. After the first oil change, load should be increased gradually with stable temperature. Following the 100-hour break-in, regular maintenance can be implemented.

How to Handle a Reducer Bearing That Gets Hot But Isn't Damaged
This article explains how to fix undamaged overheating reducer bearings, a common issue from maintenance/installation errors that speeds up wear if untreated. It lists four main causes: improper lubrication, tight bearing clearance, blocked heat dissipation, unlevel mounting. It also gives four safe solutions (lubricant check, clearance adjustment, cleaning, leveling) and key precautions, emphasizing professional operation and daily maintenance to resolve overheating, extend bearing life and cut repair costs.
