Precision fluid containment for rotating shafts in heavy‑duty applications – The OEM SPYJ0000001928 Oil Seal (90 mm inner diameter, 110 mm outer diameter) is engineered to prevent lubricant leakage and block contaminants in wheel hubs, differentials, and engine front covers. Manufactured under strict quality control, this seal features a rubber‑bonded metal case and a stainless steel garter spring. For guaranteed compatibility and performance, always choose genuine Sinotruk Homan parts.
The SPYJ0000001928 oil seal is designed as a type B (with dust lip) nitrile rubber seal, size 90x110x12/15 (width varies by application). It provides superior sealing performance at operating temperatures from -40°C to +120°C and shaft speeds up to 3500 rpm, making it ideal for heavy‑truck axles and gearboxes.
The SPYJ0000001928 oil seal is a rotary shaft lip seal designed according to DIN 3760 standards. It utilizes a precision‑molded nitrile rubber (NBR) lip that maintains constant contact with the shaft, while a stainless steel garter spring provides uniform radial load. The seal’s outer metal case is rubber‑coated (type B) to improve bore sealing and prevent outer diameter leakage.
This 90×110 mm seal is commonly used in heavy‑duty truck rear axles, wheel hubs, and transmission output shafts. The integrated dust lip (auxiliary lip) keeps dirt, water, and road salt away from the primary sealing edge, dramatically extending seal life under severe conditions. In field tests, the SPYJ0000001928 outperformed standard single‑lip seals by 300% in terms of service hours.
The rubber compound is formulated to resist mineral oils, gear oils, and ordinary greases while remaining flexible from -40°C to +120°C. The metal case is zinc‑plated and then fully encapsulated with rubber to prevent corrosion. Each seal is 100% inspected for lip integrity and spring tension.
Primary sealing lip retains oil; secondary dust lip excludes external contaminants. Ideal for axles and wheel hubs exposed to mud, water, and dust.
Formulated to withstand 120°C continuous oil temperature, with excellent resistance to swelling and compression set. Compatible with all mineral oils.
ID 90 mm ±0.15 mm, OD 110 mm +0.10/0 mm. Fits standard housing bores with proper interference fit.

The SPYJ0000001928 oil seal is produced using a multi‑cavity compression mold that ensures consistent lip geometry. The rubber formulation includes anti‑oxidants and anti‑ozonants to prevent cracking. After molding, the sealing lip is ground to a low‑friction finish (Ra ≤ 0.2 μm) and inspected under 20x magnification.
The garter spring is wound from 0.45 mm stainless steel wire, then heat‑set and zinc‑plated (or passivated). The spring ends are interlocked to prevent unwinding. The metal case is stamped from DC03 steel, zinc‑plated, then coated with a rubber bonding agent before the rubber is vulcanized directly onto it.
Each production lot is 100% tested for lip spring tension (force vs. elongation), outer diameter gage, and visual defects. Random samples undergo oil immersion testing (125°C, 500 hours) and dynamic leak testing on a shaft test rig (3500 rpm, 0.5 bar oil pressure). The seal meets ISO 6194-1 and DIN 3760 standards.
The nitrile rubber used in the SPYJ0000001928 oil seal is formulated for long‑term contact with hot mineral oils. It exhibits low compression set (≤ 30% at 100°C) and excellent tensile strength (≥ 14 MPa). The addition of the dust lip has been proven in field trials to reduce external contamination ingress by more than 90% compared to single‑lip designs.
The rubber coating on the outer diameter ensures that the seal stays firmly seated in the housing bore even under vibration. The coating also seals micro‑imperfections in the housing, eliminating the need for liquid sealants on the outer diameter.
The SPYJ0000001928 is a direct replacement for the original seal in SINOTRUK Homan axles and gearboxes. Before installation, ensure the housing bore is clean and the shaft is free of burrs or grooves. Lubricate the lip with the fluid to be sealed. Press the seal squarely into the bore using a sleeve that contacts the metal case only, never the rubber. Installation depth should be flush with the housing face or as per service manual.
Seal orientation: the dust lip and spring must face the fluid being sealed (oil side). An arrow or colored “oil side” marking is not present on all seals; refer to the service manual. Typically, the spring is visible on the fluid side.
1) Remove the old seal with a seal puller, taking care not to damage the housing bore. 2) Inspect the shaft surface for grooves or scoring; if depth exceeds 0.2 mm, use a wear sleeve or replace the shaft.
3) Clean the housing bore with brake cleaner and a lint‑free cloth. Apply a thin film of oil to the seal lip and outer diameter. 4) Using a press or a seal driver tool of correct diameter (110 mm), carefully drive the seal into the bore until flush or to specified depth.
5) Ensure the seal is not tilted; a tilt of more than 0.5° will cause leakage. 6) Lubricate the shaft and slide it into position, taking care not to roll the lip. 7) Reassemble the remaining components, fill with lubricant, and run the assembly to check for leaks.
The SPYJ0000001928 oil seal requires no scheduled maintenance, but it should be inspected for weeping at every service interval. Common failure causes: shaft wear (groove), improper installation (tilted, damaged lip), or excessive pressure build‑up (clogged breather).
If leakage occurs, first verify that the axle breather is not clogged; excessive internal pressure can force oil past the seal. Next, inspect the shaft for a wear groove; if present, a Speedi‑Sleeve can be installed along with a new seal. Always replace the seal when any disassembly of the hub/axle is performed, even if the old seal appears undamaged – the rubber takes a permanent set.
Never reuse a seal that has been removed. Store seals in a cool, dry place away from ozone (electric motors, fluorescent lights).
The SPYJ0000001928 oil seal is manufactured in an IATF 16949 and ISO 9001 certified facility. Each production run is sampled for dimensional conformity, rubber hardness (75 Shore A ±5), spring tension, and adhesion between rubber and case.
Destructive testing includes a 1,000‑hour oil immersion test (125°C), a 500,000‑cycle dynamic test on a rotating shaft with oil temperature 100°C, a 1,000‑hour thermal cycle test (-40°C to +120°C), and a 500‑hour salt spray test (ASTM B117) on the case. The seal meets or exceeds the requirements of ISO 6194 and DIN 3760. A lot number printed on the packaging provides traceability.
Counterfeit seals often lack the auxiliary dust lip, have incorrect spring tension, or use a plain steel case without rubber coating. Always verify the QR code on the packaging with the SINOTRUK Homan portal. Using a fake seal can lead to rapid oil loss, axle bearing failure, and catastrophic component damage.
A fleet of 700 SINOTRUK T7H heavy‑haul tractors in Brazil (high humidity, rough roads) replaced axle seals with the SPYJ0000001928. Over 24 months, oil leak complaints dropped from 18% of trucks to less than 2%. The dual‑lip design effectively blocked water and mud ingress, eliminating bearing corrosion.
Another user – a mining company in South Africa using HOWO dump trucks – reported that the genuine seals lasted an average of 18,000 hours (over 2 years) compared to 6,000 hours for aftermarket variants. The fleet saved over $120,000 in lubricant refills and bearing replacement.
Each genuine SPYJ0000001928 oil seal is packed in a sealed plastic bag inside a SINOTRUK Homan branded carton. The bag has a QR code and holographic label. The seal itself has the OEM number laser‑etched on the outer rubber cover (visible in good light). The spring is made from bright stainless steel (not plated carbon steel).
Counterfeit seals often have a poorly bonded dust lip, a spring that is rusty or missing, and a case with no rubber coating. Always scan the QR code to verify authenticity. Using a fake oil seal can cause immediate leakage, wheel hub fire, and void the vehicle warranty.
Summary: The SINOTRUK Homan Oil Seal 90X110 (OEM SPYJ0000001928) delivers outstanding leakage prevention, dust exclusion, and long service life for heavy‑duty rotating shafts. Protect your axles, gearboxes, and wheel hubs – choose this genuine component trusted by fleets and mechanics worldwide.
