Types of Wheel Hub Units — Generation 1, 2 and 3

Wheel bearings are commonly categorized into three generations, with matching repair kits available for selected vehicle applications. The appropriate design depends on how the bearing is mounted to the steering knuckle and whether the hub flange and ABS encoder are integrated into the assembly.
TP supplies Generation 1, Generation 2, and Generation 3 wheel hub bearings, along with related repair kits, covering a wide range of passenger car and commercial vehicle applications.

Generation 1

Wheel Bearing (press-fit)

A sealed double-row unit — angular contact ball or tapered roller — pressed directly into the steering knuckle. Hub and flange stay separate. Compact, proven and the lowest cost per piece, which is why it is still a volume seller in the aftermarket.

Typically fitted to: Older passenger cars and light-duty vehicles; many Japanese and European models from the 1990s to the early 2000s.

Generation 1 hub bearing
Generation 2

Wheel Bearing (flanged)

A mounting flange is integrated into the outer ring, so the unit bolts to the knuckle instead of being pressed in. Fewer loose parts, faster fitting, and preload is better retained than in a pressed assembly.

Typically fitted to: Mid-size and larger passenger cars, SUVs and light trucks; common on VW, Audi and BMW platforms from the 2000s onward.

Generation 2 wheel hub unit bearing
Generation 3

Hub Assembly (bolt-on)

Inner and outer flanges are combined into one unit, so bearing, hub and flange arrive as a single bolt-on assembly. No press needed, preload is set at our factory, and an ABS encoder ring can be integrated for wheel-speed sensing.

Typically fitted to: Standard on most vehicles built after 2010, and on anything with ABS or ESC where the bearing carries the speed sensor.

Generation 3 wheel hub assembly

Wheel Bearing Types Compared

Type What you get Installation Hub flange ABS encoder Unit cost
Generation 1 Sealed bearing only Press-fit into knuckle Separate No Lowest
Generation 2 Bearing + outer flange Bolt-on to knuckle Separate Optional Mid
Generation 3 Bearing + hub + flange Bolt-on, ready to fit Integrated Common Highest
Repair kit Bearing, seals, nuts, circlip Replaces worn parts only n/a n/a Lowest per repair

Not sure which generation your platform uses? Send us the OE number or the vehicle and year — we will confirm it. For a fuller explanation see What is a wheel hub unit and what types are there, or browse Wheel Bearings & Kits and Truck Bearings & Hub Units.

Applications & Vehicle Coverage

A wheel hub unit supports vehicle load, maintains wheel positioning, and, in Generation 3 designs, integrates ABS wheel-speed signal solutions. As a critical safety-related component, hub unit performance depends on precise bearing clearance, reliable sealing, and consistent manufacturing quality to ensure smooth operation and long service life.

TP wheel hub units cover European, North American, Japanese, Korean, and Chinese vehicle applications, including passenger cars, pickups, buses, medium- and heavy-duty trucks, and agricultural vehicles. With more than 200 hub references available, TP continues to expand its range according to market demand and customer requirements.

For distributors, TP provides interchange verification, private-label packaging solutions, warranty support, and technical assistance to help identify the correct application and simplify product sourcing across different vehicle models and production years.

Manufacturing & Quality

TP wheel hub unit production line

Two Plants, One Quality System

Founded in 1999, Trans Power (TP) manufactures hub bearing products under its own brand. Wheel hub units and wheel bearings are among TP's core product lines, alongside driveshaft center support bearings, clutch release bearings, hydraulic clutch systems, pulleys, and tensioners.


Manufacturing is carried out at our production facilities in Zhejiang, China, and Thailand, established in 2023. A 2,500 m² logistics centre in Shanghai supports inventory management and efficient global order fulfillment. The two-site production structure provides customers with more flexible sourcing options and stable supply capability.


TP's technical centre supports product design, drawing review, application verification, and interchange matching. OE and aftermarket reference information is provided where available, helping distributors identify equivalent TP products and efficiently match their existing inventory.

Wheel Hub Unit FAQ

What is the difference between a wheel bearing, a hub unit and a hub assembly?
They are the three generations of the same component. A Generation 1 wheel bearing is a sealed unit pressed into the knuckle, with the hub separate. A Generation 2 hub unit has a mounting flange built into the outer ring so it bolts on. A Generation 3 hub assembly combines bearing, hub and flange — and usually the ABS encoder — into one bolt-on part. See the comparison table above.
How do I know which type of wheel hub my vehicle takes?
Send us the OE number, or the make, model and year. We will confirm the generation, whether an ABS encoder is required, and the matching TP reference. Guessing from photographs is the commonest cause of a wrong order in this category.
Do your hub units include the ABS encoder ring?
Where the platform requires one, yes. Encoder pole count and polarity are platform-specific and cannot be substituted, so always quote the OE number when enquiring — a hub that is dimensionally correct but has the wrong pole count will throw an ABS fault.
What is your MOQ and lead time for hub units?
MOQ starts at 50 pcs per reference, which is lower than most China hub suppliers. Lead time depends on whether the reference is held at our Shanghai logistics centre or scheduled for production, and whether you ship from China or Thailand. Send your reference list for a per-line quotation.
Can I choose whether my order ships from China or Thailand?
Yes, subject to which references each plant runs. Buyers in markets where tariff treatment differs by country of origin use this regularly — tell us your destination market and we will advise which site is the better route.
Do you supply hub unit repair kits as well as complete assemblies?
Yes. Repair kits containing the bearing, seals, nut and circlip are available for the references that support them — often the more economical option for a workshop replacing a worn bearing rather than a damaged hub.
Can you produce hub units under our own brand?
Yes — OEM and ODM are both supported, including logo-printed bags, custom boxes and outer cartons, plus non-standard designs built to your drawing. Drawing confirmation happens before production starts.
Can I test samples before placing a bulk order?
Yes. We recommend it for every new reference — bench-check fitment, running noise and seal performance yourself before committing. Samples are available on request.

What Is Inside a Wheel Hub Assembly

Eight parts make up a Generation 3 wheel hub assembly. For a distributor, two of them decide your warranty return rate: the seal design and the grease specification. Everything else is dimensional.

Hub flange Carries the wheel studs and takes the clamping load from the wheel bolts.
Inner & outer races Hardened, ground raceways that set running accuracy and noise behaviour.
Ball or roller elements Double-row angular contact balls, or double-row tapered rollers where the load case is heavier.
Cage Keeps the elements evenly spaced so load shares correctly across the row.
Grease charge Sealed-for-life lubrication matched to the operating temperature range.
Seals Contact or low-friction seals that keep water, salt and road grit out of the raceway.
ABS encoder ring Magnetic pole ring read by the wheel-speed sensor. Pole count and polarity are platform-specific.
Mounting flange Bolts the unit to the steering knuckle on Gen 2 and Gen 3 designs.

Ask us for the seal type and grease specification on any reference before you commit — it is the fastest way to compare two quotations that look identical on dimensions.
