China 6310 Deep Groove Ball Bearing Suppliers - High Precision Factory Bearings for Industrial and Medical Applications
Deep Groove Ball Bearings Introduction
Deep groove ball bearings mainly take radial load as well as moderate axial load. With a low coefficient of friction, high limiting speed, wide size range, and versatile structural combinations, they are suitable for tractors, electric motors, automobiles, motorcycles, and other standard machinery as an essential component in the machinery industry.
These bearings are suitable for high-speed or even extremely high-speed operations and offer high durability without requiring frequent maintenance. Widely applied across precision instruments, low-noise motors, automobiles, and general engineering, they represent the most common bearing type in modern industrial systems.

Frequently Asked Questions (FAQ)
What are the boundary dimensions and load ratings for the 6310 bearing?
The 6310 deep groove ball bearing features an inner diameter of 50 mm, outer diameter of 110 mm, and a width of 27 mm. It offers a basic dynamic load rating (Cr) of 62,000 N, a static load rating (C0r) of 38,000 N, and a limiting speed of 6,200 r/min.
Which seal types and cage materials are available for custom orders?
We provide Open, ZZ (metal shields), and 2RS (rubber seals) configurations. Cages can be customized using brass, pressed steel, nylon, and other materials depending on your application temperature and operational speed.
What material grade and hardness standard are used?
Our bearings are manufactured from high-quality Chrome Steel GCr15 heat-treated to an optimal hardness range of HRC 61 - 65, ensuring high wear resistance, fatigue strength, and extended service life.
What precision and internal clearance grades are available?
We supply precision grades across P0, P6, P5, P4, and P2, with radial internal clearance options including C0 (standard), C2, C3, C4, and C5 to match exact equipment tolerances.
What are the standard delivery lead times for bulk purchases?
For orders of 1 to 300 pieces, estimated delivery time is approximately 2 days. For volume orders exceeding 300 pieces or custom OEM requirements, lead times are scheduled and negotiated according to specific production plans.
How should deep groove ball bearings be maintained to prevent premature wear?
Maintain concentric alignment during installation without forced fitting, replenish suitable grease or oil periodically, and routinely track operating temperatures, vibration, and noise levels to prevent early fatigue or contamination issues.
