Product Introduction: Deep Groove Ball Bearings

The most versatile and widely used type of rolling bearing, our Deep Groove Ball Bearings are engineered for high performance and reliability. The simple yet robust design features a smooth raceway geometry that allows them to handle not only heavy radial loads but also bidirectional axial loads with ease.

Designed for a vast range of applications—from electric motors and pumps to gearboxes and industrial machinery—these bearings ensure quiet operation, low friction, and suitability for high-speed rotation. We offer various configurations to meet your specific needs, including open types for high-speed applications, and shielded (2Z) or sealed (2RSR) variants that are pre-lubricated and provide lifelong maintenance-free operation by protecting against contaminants.

Choose our Deep Groove Ball Bearings for a solution that delivers durability, efficiency, and exceptional value in every rotation.

Deep Groove Ball Bearing Series Overview

Series	Bore Diameter (d)	Common Applications & Features
6800 Series	Ultra-small to small	Ideal for compact motors, instruments, and office automation where space is limited.
6900 Series	Small	Offers higher load capacity than the 6800 series for applications like power tools and small appliances.
16000 Series	Small to medium	Thin-section design suitable for applications with limited axial space.
6000 Series	Small to medium	The most popular series, versatile for electric motors, pumps, and general machinery.
6200 Series	Medium	Designed for higher radial load capacity, commonly found in gearboxes, conveyors, and agricultural equipment.
6300 Series	Medium to large	Features the largest load capacity within standard single-row bearings, used in heavy-duty industrial gearboxes and fans.

 

Common Suffix Codes for Configuration:

· 2Z / ZZ: Sheet steel shields on both sides for protection with low friction.
· 2RSR / 2RS1 / 2RSH: Rubber seals on both sides for superior contamination protection in dirty or moist environments.
· N / NR: Snap ring groove on the outer ring, allowing for simple axial location and compact housing design .
· M / MA: Machined brass cage for high-strength and high-speed applications .
· C3: Greater than normal internal radial clearance for applications involving interference fits or high temperature differences .
