The NSK 28BWD01ACA is a double-row angular contact ball bearing specially designed for wheel hub applications in automotive systems. Built by NSK, a world-renowned manufacturer of high-precision bearings, this part provides stable, smooth rotation and reliable support for radial and axial loads typically encountered in wheel hub assemblies. This bearing is often used as an OEM-equivalent wheel bearing in competitive aftermarket applications.

Technical Specifications

Vehicle Compatibility (Fitment Examples)

Unlike some bearings that are sold with official OEM vehicle fitment lists, the NSK 28BWD01ACA designation is identified by its bearing dimensions and type (28×61×42 mm angular contact) rather than a specific published list from NSK. However, aftermarket hub bearing catalogs and VIN match data show that bearings with this size and design — often listed equivalently as NSK 28BWD01 / 28BWD01ACA / DAC286142AWCS40 — are used in a range of Toyota vehicles where the original equipment wheel hub bearings are specified in this dimension class.

Based on compatible hub designs and cross references for NSK 28BWD01, common vehicle applications include:

Toyota Vehicles (Typical Fitment Range)

• Toyota Corolla / Corolla Wagon – 1984 to 1992
• Toyota Corolla FX / Corolla AWD variants – mid-1980s to early 1990s
• Toyota Celica / Celica AWD – late 1980s models
• Toyota Paseo / Tercel / Tercel Wagon – 1980s to early 1990s
• Toyota Yaris (early generation) – late 1990s
• Toyota Carina, Corona, and other Toyota chassis with similar 28×61×42 hub bearing specs – various years

Fitment Notes: These vehicle examples come from aftermarket fitment data for 28BWD01A / 28BWD01 bearings of the same size and type, which share dimensions and load ratings with the 28BWD01ACA designation. Always verify the OEM hub bearing part number for your exact model, generation, and engine/transmission combination before purchase.

Cross-Reference & OEM Equivalent Numbers

To help verify correct application, bearings with the same dimensions and type are sometimes listed under these numbers:

NSK / Equivalent Part Designations:
• NSK 28BWD01 – angular contact double row wheel bearing
• DAC286142AWCS40 – equivalent designation used in some parts catalogs

Aftermarket bearing references (vehicle hub applications) in parts data often list 28BWD01A and similar angular contact bearings in compatibility tables, which helps identify the general vehicle usage.

Features & Benefits

• Angular Contact Design: Double-row ball bearing layout provides stable support for both radial and axial loads, crucial for wheel hub rotation and braking forces.
• Robust Dimensions: 28 mm bore × 61 mm outer × 42 mm width matches common hub bearing requirements where space and load conditions demand precision bearing design.
• High Durability: NSK’s precision manufacturing and quality control ensure long service life and reliable performance under typical automotive road conditions.
• Compact & Reliable: Designed for wheel hub rotation systems allowing smooth wheel movement and reduced noise.

Important Selection & Fitment Notes

• Match OEM Bearing Specs: Always check the original bearing’s part number or dimensions in your vehicle’s service manual or parts catalog before ordering.
• Verify Hub Type & ABS Sensor: Some vehicles use hub assemblies with integrated ABS tone rings or sensor components; confirm these features match your application before replacement.
• Professional Installation: Wheel hub bearings require correct press-fit and torque settings — professional installation ensures safe and long-lasting performance.

Where It’s Used

Automotive Applications:

• Front or rear wheel hub bearing assemblies (vehicles with this bearing spec)

• Rotary joints in suspension hubs where combined load support is needed

Industrial Applications:

• Rotating assemblies with similar size and load requirements (non-automotive may vary)
