Lubricant deterioration/insufficient, gear impact, and assembly deviation. Regular oil changes and standardized assembly are required.
Strictly control cleanliness, use ultra-clean grease to prevent cutting fluid intrusion, and regularly check preload.
Choose reinforced sealed bearings, regrease regularly, and remove mud and sand after operation to prevent impurities.
Observe the vibration spectrum (to check for fatigue), temperature (to determine lubrication/overload), and lubricant ferrography (to analyze wear).
Wheel-rail misalignment, brake heat transfer, and track iron chips intrusion into the seal.
Choose a waterproof and sealed model and check the aging of the sealing ring regularly; if there is a leak, clean it, change the grease and repair the seal in time.
This is often due to an overly loose fit or insufficient interference fit. Tighten tolerances and tighten the fit if necessary.
Use IP65+ protection. Rinse and regrease after operation, changing grease every 50 hours.
Use titanium alloys or ceramics, optimize the raceway structure, and perform finite element simulation to verify strength.
Choose stainless steel and NSF H1-grade grease. Maintain anti-contamination measures and use sterile tools.
