Description
Products Description
The Inner Rear Hub Oil Seal (also known as rear axle oil seal or rear wheel bearing seal) is a critical component of your ISUZU truck's rear axle assembly. It prevents gear oil or wheel bearing grease from leaking out of the rear hub and stops dirt, water, and road contaminants from entering the bearing cavity .
This inner rear hub oil seal is specifically designed for ISUZU medium-duty truck models – including the popular 700P, NKR, NLR, NPR, and NQR series. These trucks are widely used for cargo transport, delivery services, and commercial fleets worldwide.
With a precision size of 81.7 mm inner diameter × 121 mm outer diameter × 12/19 mm stepped width, this seal is engineered to fit the exact specifications of ISUZU rear axle hubs. When the original seal wears out or becomes damaged, axle oil can escape, leading to premature bearing failure, brake contamination, and potential safety hazards .
Manufactured with high-quality elastomer compounds and precision steel spring reinforcement, this seal provides a reliable barrier that keeps your rear wheel bearings properly lubricated and protected .
Choose from 3 quality levels – China ISUZU (Qingling) Quality / Aftermarket Quality / Famous Brand Quality to suit different budget and durability requirements.

FAQ
Q1: What is the difference between the three quality levels?
| Quality Level | Key Differences |
|---|---|
| Aftermarket Quality | Standard NBR rubber – economical choice for basic replacement |
| China ISUZU (Qingling) Quality | Factory-grade materials – meets ISUZU OEM specifications – enhanced heat and oil resistance – best value |
| Famous Brand Quality | Premium elastomer compounds (often FKM/Viton) from Tier 1 suppliers – superior durability and longer service life – better chemical resistance |
Q2: What does "China ISUZU (Qingling) Quality" mean?
A: Qingling Motors is ISUZU's long-term joint venture partner in China, producing ISUZU-licensed commercial vehicles since 1985. China ISUZU Quality parts are manufactured to the same specifications as original equipment supplied to ISUZU's China production lines.
Q3: What do the dimensions 81.7×121×12/19 mean?
A: This indicates a stepped seal design:
81.7 mm – Inner diameter (fits onto the axle shaft)
121 mm – Outer diameter (presses into the hub bore)
12 mm / 19 mm – Stepped width (different thicknesses across the seal profile)
Please measure your original seal before ordering to confirm compatibility.
Q4: How many seals do I need for both rear wheels?
A: Most ISUZU rear axles require 1 inner seal per rear wheel. For both rear wheels, order 2 pieces (one for each side).
Q5: Should I replace the rear wheel bearings at the same time?
A: Highly recommended. If the oil seal failed, the bearings may have been contaminated or run with insufficient lubrication. Inspect bearings carefully and replace if any signs of wear, pitting, scoring, or discoloration.
Q6: Is this for oil-bath or grease-packed rear hubs?
A: This seal is compatible with both systems. ISUZU medium-duty trucks may use either:
Oil-bath hubs – Hub cavity filled with gear oil
Grease-packed hubs – Bearings packed with grease
Please verify your vehicle's configuration before ordering.
Q7: Do you offer wholesale pricing for bulk orders?
A: Yes. Please contact us with your quantity and preferred quality level for a competitive quote.
Q8: What is your warranty policy?
A: This product comes with a 1-year warranty against manufacturing defects. Please contact our support team for any issues.
Q9: Can I get custom branding or packaging?
A: Yes. Custom packing with your logo or specifications is available for bulk orders.
