As the “joints” of mechanical equipment, deep groove ball bearings directly impact device longevity and efficiency. Master these maintenance techniques to prevent 70% of premature bearing failures:
1.Contamination Control: Create Barriers
- Workspace: Clean shafts and housings thoroughly before installation, use seals to isolate dust
- Cleaning Method: Wipe with lint-free cloth + specialized cleaner only (compressed air blasting prohibited)
- Case Study: Packaging plant had 5×6205 bearings burnt out in 3 months due to fiber ingress
2.Precision Lubrication: Quality & Quantity Balance
- Grease Selection: Refer to ISO 6743-9, use Li-based LGEP 2 for -30℃~120℃ environments
- Fill Formula: 30% of bearing internal space (reduce to 15% for high-speed applications)
- Monitoring: Detect lubrication decay via ultrasonic detector (>8dB increase requires regreasing)
3.Installation Protocols: Avoid Force Damage
- Cold Mounting: Use induction heater for bearings >80mm bore (110℃±10℃ controlled)
- Pressure Principle: Apply force only to interference-fit ring (press inner ring if tight-fit)
- Torque Limit: Max 45N·m for M10 mounting bolts to prevent false brinelling
4.Condition Monitoring: Three-Stage Alert System
| Stage | Vibration(mm/s) | Temp. Warning | Action Plan |
| Normal | <1.2 | ΔT＜15℃ | Routine inspection |
| Early Failure | 1.2-2.5 | ΔT=15-40℃ | Lubrication within 72h |
| Critical | >2.5 | ΔT＞40℃ | Immediate shutdown |
Benefit: Standardized implementation extends bearing life to 220% of L10 rating. Contact our engineering team now for customized maintenance solutions!
