Products Description
NBR Motorcycle Wheel Bearing Seal
Double Lip Bearing Shaft Seal FKM High Temperature Resistant for Motors
This is a double-lip radial shaft seal made from NBR (nitrile rubber) or FKM (Viton®), reinforced with an internal stainless steel garter spring.
It is used in front and rear wheel hub assemblies of scooters, motorcycles, and light three-wheelers operating in wet or dusty conditions.
Features
Reliable Seal
Dual-lip design keeps grease in, blocks dust and water.
Oil & Heat Resistant
NBR resists lubricants, works from −30℃ to +120℃.
FKM option withstands up to +200℃.
Applications
Front and rear wheel hubs of motorcycles, scooters, and e-bikes
Light-duty three-wheel cargo/passenger vehicles
Compatible with standard deep groove ball bearings (6000, 6200, 6300 series)
Ideal for markets with monsoon climates, unpaved roads, or frequent washdowns

FAQ
Which side faces inward during installation?
The side with the visible garter spring must face toward the grease/lubricant (inside the hub). The smooth outer lip faces outward to repel contaminants.
Can you match a competitor's seal (e.g., SKF, NOK)?
Yes. Send us the part number or physical sample-we'll replicate dimensions, lip geometry, and spring load within ±5%.
What's the difference between NBR and FKM for motorcycle use?
Use NBR for standard bikes (cost-effective, good oil resistance). Choose FKM only if exposed to brake fluid, high-temp exhaust proximity, or continuous >120°C operation.
Do you supply seals for electric scooter hubs?
Yes. We offer low-friction NBR formulations to minimize drag in e-scooter wheel motors-validated by torque-loss testing.
How do you prevent lip damage during automated press-fit assembly?
We offer chamfered ID edges and optional PTFE-coated lips to reduce insertion force by up to 30%. Provide your press speed/load for optimization.
