Maintenance and Care Suggestions

Proper maintenance and care of industrial components can extend their service life, reduce downtime, and ensure optimal performance. Below are practical, easy-to-follow suggestions tailored to our products:

1. Routine Inspection (Weekly)

Check the GROUNDING BAR ASSEMBLY 118866 for loose connections or corrosion, and verify ground resistance (should be ≤0.5Ω). Inspect bearings (117987, 109519) for unusual noise, overheating, or vibration, and check lubrication levels. Examine the CALIPER DISC BRAKE 109528 for brake pad wear (replace if wear exceeds 3mm) and brake fluid leaks. Clean the HEAT EXCHANGER 30122104 to remove dust and debris, ensuring unobstructed heat transfer.

2. Regular Maintenance (Monthly)

Lubricate all bearings with high-temperature lithium grease (NLGI Grade 2), ensuring full coverage of the roller and raceway. Replace SEAL POLYPAK 98291 and SEAL OIL 91250-1 if signs of aging, cracking, or leakage are found. Tighten all fasteners (50206-B, 87074-8-B) and check lockwire (Z6001/Z6001.9) for signs of fatigue, replacing any loose or broken lockwire. Adjust shims (110147 series, 109586 series) to ensure proper component alignment, reducing wear and vibration.

3. Long-Term Storage & Special Care

Store all components in a dry, ventilated warehouse with a temperature of 0℃ to 35℃ and relative humidity ≤ 60%. For grounding components (118866, 118993), store them in a moisture-free environment to prevent corrosion. Bearings should be coated with anti-rust oil and wrapped in waterproof paper to prevent rust. Brake components should be stored in a clean environment to avoid dust buildup on brake pads. Heat exchangers should be flushed with clean water before storage to remove oil and debris.

On-Site Fault Maintenance Cases

Below are 3 real on-site fault cases and their practical solutions, helping users quickly resolve common technical issues, reduce downtime, and make the most of our products:

Case 1: Grounding Bar (118866) High Resistance and Electrical Fault

Fault Phenomenon: A power plant reported frequent electrical faults and tripped circuit breakers, traced to the GROUNDING BAR ASSEMBLY 118866 with a measured ground resistance of 2.3Ω (exceeding the safe limit of ≤0.5Ω). Solution: Inspect the grounding bar and find corrosion on the copper connections and loose cable lugs (94872-3). Clean the corrosion with a wire brush, replace the loose lugs, and re-tighten all connections. After treatment, the ground resistance dropped to 0.3Ω, and electrical faults stopped. Cause Analysis: Corrosion and loose connections increased ground resistance, leading to ineffective fault grounding. Suggestion: Inspect grounding components monthly for corrosion and loose connections, especially in humid environments.

Case 2: Spherical Roller Bearing (117987) Seizure and Equipment Shutdown

Fault Phenomenon: A manufacturing plant reported that a crusher shut down unexpectedly, with the BEARING, SPHERICAL ROLLER – COMPOUND LOWER 117987 seized and overheated. Solution: Disassemble the bearing and find it was starved of lubrication, with severe wear on the rollers and raceway. Replace the bearing with a new 117987, clean the bearing housing, and refill with high-temperature lithium grease. After replacement, the crusher resumed normal operation. Cause Analysis: Lack of scheduled lubrication led to dry friction and bearing seizure. Suggestion: Implement a weekly lubrication schedule for all bearings, and check lubrication levels daily in high-load applications.

Case 3: Caliper Disc Brake (109528) Poor Stopping Power

Fault Phenomenon: A construction company reported that the BRAKE, CALIPER DISC 109528 on a crane had poor stopping power, leading to safety concerns. Solution: Inspect the brake and find that the brake pads were worn beyond the limit (4mm wear) and the brake fluid was contaminated. Replace the brake pads, flush the brake system, and refill with clean brake fluid. After treatment, the brake’s stopping power was restored to 100% of rated capacity. Cause Analysis: Worn brake pads and contaminated brake fluid reduced braking efficiency. Suggestion: Inspect brake pads monthly and replace when wear exceeds 3mm, and change brake fluid every 6 months.
