Product Introduction

The DG409026 is a specialized automotive bearing engineered to deliver exceptional performance in high-stress wheel hub and transmission environments. Measuring 40 x 90 x 26 mm, this bearing is designed to handle demanding radial loads and moderate axial thrust. Manufactured from premium, high-carbon GCr15 chromium steel and featuring advanced deep-groove or specialized internal geometry, it ensures a prolonged operational lifespan with minimal frictional loss. It is a critical replacement component for international auto parts distributors focusing on drivetrain and chassis reliability.

Applications

Specific passenger car and light truck wheel hubs.
Automotive manual and automatic transmission systems.
Aftermarket drivetrain rebuilds and chassis maintenance.

FAQ

Q: What does the "DG" prefix stand for?
A: In automotive bearing nomenclature, "DG" typically denotes a specialized Deep Groove ball bearing design optimized for auto hub or transmission applications.
Q: Can this bearing be used in high-temperature environments?
A: Yes, it is factory-lubricated with a high-temperature synthetic grease designed to withstand the heat generated by friction and braking.
