40BWD08A Automotive Wheel Hub Bearings 40X76X33mm Angular Contact Ball Bearings

Product Introduction

40BWD08A Automotive Wheel Bearing – 40X76X33mm Double Row Angular Contact Ball Bearing

The 40BWD08A is a precision‑engineered double‑row angular contact ball bearing, specifically designed for automotive wheel hub applications where compact design, high rotational accuracy, and reliable load support are essential. With its dimensions of 40 mm inner diameter × 76 mm outer diameter × 33 mm width, this bearing offers an excellent balance of load capacity and space efficiency for modern passenger car suspension and steering systems.

Manufactured to P0 precision class, the  40BWD08A ensures smooth rotation, precise alignment, and consistent performance across a wide range of speeds and operating temperatures. It features 2RS‑type rubber seals on both sides, which provide effective protection against water, dust, and contaminants while retaining the factory‑applied grease for reduced maintenance and extended service life. The bearing is constructed from high‑grade GCr15 chrome steel for both rings and balls, delivering exceptional hardness, wear resistance, and fatigue strength. A durable nylon cage minimizes friction, reduces operating noise, and ensures stable performance even under high‑speed conditions.

As a single‑row angular contact design, this bearing efficiently supports combined radial and axial loads, making it particularly suitable for wheel hub positions where space is limited but precise load handling is required. It is an ideal replacement choice for front wheel hub assemblies in a wide range of sedans, compact cars, and light vehicles, contributing to improved steering responsiveness, reduced vibration, and enhanced overall driving safety and comfort.
