Product details
This 240×272×28mm TB-type rear wheel hub oil seal is a dedicated aftermarket sealing solution for heavy duty commercial truck rear axle systems, matching OEM part number HD90149346012, specifically designed for Hande 40T series drive axles.
It adopts an exposed cold-rolled steel outer case for rigid mounting and structural stability, paired with precision-machined primary oil-sealing lip and secondary dust-proof lip. A built-in carbon steel garter spring maintains consistent radial preload on the shaft surface, even under heavy load vibration and road impact. The inner lip retains hub gear oil and bearing grease inside the assembly, while the outer lip blocks road dust, mud, grit and splash water from invading the bearing chamber, effectively extending the service life of wheel hub bearings and axle components.
Produced with strict dimensional tolerance control, it matches original OEM installation dimensions and can be directly fitted without modification. Manufactured in Hebei, China with mature truck seal supply chain, we maintain stable bulk stock to support fast delivery and large-volume procurement for global truck aftermarket channels.

Selection guide
Selection Guide
- Confirm OEM cross reference number HD90149346012, and verify shaft ID 240mm, housing OD 272mm, thickness 28mm and TB double-lip metal case structure.
- Standard NBR version for normal truck operating conditions (-30℃~120℃); select FKM upgrade for high-temperature and chemically aggressive environments.
- For long-term fleet procurement projects, contact us for exclusive bulk pricing and dedicated supply schedule.
Installation Steps
Surface Preparation
Thoroughly clean the rear hub housing bore and shaft surface, remove old seal residue, dirt, rust and metal burrs.
Pre-lubrication
Apply matching hub gear oil or bearing grease evenly on the sealing lip and shaft mating surface. Dry installation is strictly prohibited as it will cause premature lip wear and failure.
Orientation Confirmation
The main sealing lip faces the lubricant cavity side; the dust-proof lip faces the wheel outer side. Reverse installation will cause oil leakage and loss of mud protection.
Press-fit Installation
Use a dedicated press sleeve tool to press the seal in evenly and vertically. Never strike the metal case directly to avoid seal deformation and lip tearing.
Post-installation Check
Ensure the seal sits fully flush inside the housing bore without tilt or offset. Inspect the sealing lip for nicks, scratches and deformation.
Function Test
Manually rotate the wheel hub assembly to confirm smooth rotation without abnormal binding resistance.

FAQ
I only have a competitor/OEM part number—can you cross-reference?
Yes. Send the reference PN, ID×OD×height in mm, and duty (media, temperature, pressure, speed). We match equivalents in the catalog; the Cross Reference page also searches by keyword. Final selection follows drawing and duty confirmation — do not order from a photo alone.
Do you support OEM/ODM, private packing and marking?
Yes — OEM/ODM from drawings or samples, plus agreed packing and marking. Share target-market compliance needs and annual volume; RFQ confirms process, tooling cost and cadence. VKEFOT is the export brand of the Xingtai factory, not a trading desk.
TC vs TB oil seal: which should I specify?
For a rotary shaft that needs a dust lip plus oil lip, start with TC (rubber-covered dual-lip is common); TB is typical when a semi-metal case needs a stiffer bore fit. Shaft diameter, housing, runout and dust still decide. Send ID×OD×height in mm and speed on the RFQ — not only a competitor photo.
NBR vs FKM oil seal for hot engine oil?
Continuous engine-oil duty near 120°C or fuel exposure should be reviewed as FKM; general mineral oil at moderate temperature and cost-sensitive repair jobs often stay NBR. Brown color is not proof of FKM. The quote names the grade and temperature limit — do not order by color.
Oil seal vs O-ring: when do I use which?
Use a metal-cased radial shaft (skeleton) oil seal for rotating shafts; use an O-ring for static glands or reciprocating grooves. An O-ring on a rotary shaft wears out quickly. VKEFOT makes both — state motion type (rotary/static/reciprocating) and ID×OD×section on the RFQ.
Cassette seal vs dual-lip TC for dusty construction equipment?
Ag gearboxes and construction travel shafts with mud and long service intervals should be reviewed as cassette/combined seals; many automotive hub repair jobs stay dual-lip TC. Cassette packs are thicker and need different bore and axial space. A job-site photo is not enough — send ID×OD×height.
Xingtai oil seal factory vs trading company — how do I tell?
VKEFOT is the export brand of Xingtai Hanchi Intelligent Technology Co., Ltd. Mixing, vulcanization and outgoing inspection run in Xingtai, then goods export to Europe, North America, the Middle East and Southeast Asia. A trading desk usually cannot change compound or cut tooling. For OEM drawings, ask who runs the process and QC — not only catalog price.
What is a skeleton / radial shaft oil seal?
A skeleton oil seal is a metal-cased radial shaft seal: the rubber lip rides the shaft and the case holds interference in the bore. Common styles include TC, TB and TA. Minimum spec is ID×OD×height in mm, compound and duty. VKEFOT catalogs automotive and industrial shaft seals; trust the product-page dimensions.
What do ID, OD and height mean on an oil seal RFQ?
ID is inside diameter (shaft), OD is outside diameter (bore), height is axial width, all in millimetres. Missing any one blocks a cross-reference. Example: 56×112×8/10 means 56 mm ID, 112 mm OD, 8/10 mm height. Put those three numbers and the compound on the RFQ.
Which oil seal for an automotive wheel hub or differential pinion?
Hub repair jobs often use dual-lip TC; differential pinion shafts often need a secondary lip or split height (e.g. 8/10 or 12/22 mm). Use measured or OEM dimensions — not a marketplace title. VKEFOT application pages cover drivetrains and hubs; send an OEM number or ID×OD×height on the RFQ.
How to select oil seals for ag gearbox and PTO shafts?
Ag gearboxes and PTO shafts see dust and shock — prefer a dust lip or cassette, with NBR or FKM matched to gear oil and temperature. Do not force a passenger-car hub seal onto a PTO shaft. Send shaft, bore, height and whether mud/water is present, then RFQ.
What matters for pump, valve and compressor shaft seals?
Match media (oil, water, gas) and temperature first, then lip style and compound; do not default to cheap NBR for high speed or dry running. Put shaft runout and eccentricity on the RFQ. VKEFOT application cases include pumps, valves and compressors — still use measured sizes.
Does a brown oil seal mean it is FKM?
No. Brown NBR is common; color is not proof of FKM. For heat or fuel duty, write temperature and media on the RFQ so the factory names the grade. Ordering by color is a frequent cause of early leak.
Can you quote an oil seal from a photo only?
Not as a firm quote. We need at least ID×OD×height in mm, ideally compound and speed. A photo can show lip count and case style; it does not replace dimensions. Incomplete RFQs get a request for those three numbers before price.
If a new oil seal leaks quickly, is it always a bad seal?
Not always. Rough shaft finish, runout, cocked installation or the wrong compound also leak early. Check size and media/temperature match before blaming the part, then inspect the journal. Note time-to-fail (e.g. 50 hours) on the RFQ so we diagnose — do not just buy a cheaper seal.
What is needed for private-label OEM packing of oil seals?
Private packing and marking need annual volume, target-market compliance and artwork; tooling cost and cadence are confirmed on the RFQ — not a one-line “please OEM”. VKEFOT runs OEM/ODM after drawings or samples are complete.
Who is VKEFOT and how does it relate to Xingtai Hanchi?
VKEFOT manufactures oil seals, O-rings and custom rubber seals in Xingtai and exports to Europe, North America, Middle East and Southeast Asia. The manufacturer is Xingtai Hanchi Intelligent Technology Co., Ltd. Use this wording on quotes and certificates — do not invent alternate spellings of the brand.
Does this seal cross reference OEM number HD90149346012?
Yes, this is an aftermarket replacement seal with dimensions matching OEM HD90149346012, direct drop-in installation without modification.
What axle models is this 240x272x28mm seal compatible with?
It is verified to fit Hande 40T series drive axle heavy duty truck rear wheel hub systems.
What type of seal is HD90149346012?
It is a TB type metal-cased double-lip oil seal, with exposed steel outer case and NBR sealing lips, designed for truck rear wheel hub sealing.
