Case Studies
Case 1: Custom Cassette Seal Development for a Leading Italian Axle Manufacturer

Customer Profile: A top-tier OEM manufacturer based in Northern Italy, specializing in high-performance agricultural and truck axles.
The Challenge: The client faced recurring bearing failures in their heavy-duty tractors due to mud and slurry ingress during harvest season. Standard rotary seals could not withstand the high-contamination environments.
Our Solution (OEM/ODM): Jinwo's engineering team developed a customized multi-lip Cassette Seal with a reinforced stainless steel sleeve and high-grade FKM (Viton) lips. We optimized the grease-filled labyrinth structure specifically for their axle housing dimensions.
Result: The new design passed a 2,000-hour extreme durability test without a single leak. The client transitioned to an exclusive ODM partnership, now placing annual orders exceeding $500,000.

Case 2: Specialized Engine Overhaul Kits for a North American Fleet Service Provider

Customer Profile: A large-scale commercial fleet maintenance group in the United States, managing over 5,000 Class 8 trucks.
The Challenge: The client was struggling with the high cost of original equipment kits and the inconsistent quality of cheap aftermarket seals, which led to frequent engine "comebacks" and downtime.
Our Solution: We curated a professional-grade Engine Overhaul Sealing Kit featuring Jinwo's proprietary low-friction crankshaft oil seals and valve stem seals. Every seal was engineered to match or exceed OE specifications for thermal cycling resistance.
Result: By switching to Jinwo, the client reduced their maintenance costs by 35% while maintaining an identical service life to the original parts. This has led to a stable, long-term supply contract for their nationwide service centers.

Case 3: High-Pressure Hydraulic Sealing System for a German Forklift Brand

Customer Profile: A renowned German manufacturer of industrial material handling equipment and electric forklifts.
The Challenge: Their new generation of compact electric forklifts required hydraulic seals that could operate at higher pressures with minimal friction to preserve battery life.
Our Solution: Jinwo provided a comprehensive Hydraulic Sealing Package, including high-performance PTFE-based Piston Seals, specialized Guiding Components, and NBR-90 Back-up Rings. Our solution utilized a low-friction material compound developed specifically for electric fluid power systems.
Result: The forklift's hydraulic efficiency improved by 12%, significantly extending the vehicle's operational hours per charge. Jinwo is now their primary strategic partner for hydraulic sealing components in the Europe, Asia, and Africa (EMEA) regions.
