6300 and 6400 Series Deep Groove Ball Bearings are heavy-duty single-row bearings designed for applications requiring higher radial load capacity, improved durability and reliable operation under demanding working conditions.

Compared with standard 6000 and 6200 series bearings, the 6300 and 6400 series feature larger cross-sectional dimensions, allowing them to support higher loads while maintaining smooth rotation and long service life.

For global distributors, OEM manufacturers and industrial equipment suppliers, selecting heavy-duty deep groove ball bearings requires careful consideration of load capacity, operating speed, sealing performance, lubrication, dimensional compatibility and long-term supply reliability.

We supply high-quality 6300 and 6400 Series Deep Groove Ball Bearings with open, ZZ shielded and 2RS sealed configurations, supporting standard replacement applications and customized OEM requirements.

Product Overview of 6300 and 6400 Series Bearings

6300 and 6400 series bearings are designed with deep raceway grooves and optimized internal geometry, enabling them to handle mainly radial loads while accommodating moderate axial loads.

Key advantages include:

• Higher load carrying capacity

• Stronger structural rigidity

• Stable operation under continuous loads

  Long service intervals

• Standardized dimensions for easy replacement

These bearings are widely used in machinery where reliability and durability are more important than compact size.
