National 510033 Wheel Bearing

National 510033 is a front inner wheel bearing built for precise fitment and dependable wheel support. It is designed to meet or exceed OE quality standards and is manufactured to exacting tolerances for lasting performance and extended bearing life.

Key Features

  • Double row angular contact wheel bearing design
  • FWDB series construction for front wheel applications
  • 34.000 mm bore and 68.000 mm outside diameter
  • 37.000 mm width for proper bearing seating
  • OE-style dimensions for accurate replacement fit
  • National 510033 part number for easy identification

Detailed Description

This National wheel bearing is engineered for front inner placement and matches the dimensional requirements listed for the application. With a double row angular contact design, it is built to handle combined radial and axial loads commonly seen in front wheel assemblies. It is a direct-fit replacement for select 1990-1993 Geo Storm, 1991-1993 Isuzu Stylus without Lotus Suspension, and 1990-1992 Isuzu Impulse without Lotus Suspension. This part also cross-references SKF FW187 for the same application.

What It Helps Address

  • Wheel noise from a worn front inner bearing
  • Excessive play or looseness in the wheel assembly
  • Rough rotation caused by bearing wear
  • Uneven front-end feel related to bearing deterioration
  • Replacement needs during driveline and axle service

Installation Notes and Tips

Verify bore, outside diameter, and width before installation to confirm proper seating in the hub assembly. This bearing is listed for front inner use on the specified Geo Storm, Isuzu Stylus, and Isuzu Impulse applications, so match the vehicle configuration carefully, including the Lotus Suspension note where applicable. Clean the mating surfaces thoroughly and inspect related hub and seal components before assembly.

Quality Assurance

National manufactures this bearing to meet or exceed OE quality standards, using controlled production methods intended to support consistent fit and long service life. The 510033 is built to the dimensional and design requirements expected for a premium replacement wheel bearing.
