Deep Groove Ball Bearings: Features, Classification, Models & Applications

Deep groove ball bearings are the most widely used rolling bearings in the mechanical industry. With simple structure, low friction, high speed performance and strong versatility, these standard bearings can bear both radial load and bidirectional axial load. Available in open and sealed types with complete series models, they suit nearly all general mechanical and daily equipment scenarios.

1. Main Features

•Simple & Versatile Structure: Consists of outer ring, inner ring, steel balls and cage. Easy to install and maintain, suitable for most general industrial applications.

•Dual Load Capacity: Supports radial load and certain bidirectional axial load with low friction coefficient and high limiting speed for stable high-speed operation.

•Multiple Sealing Options: Open type for clean environments; dust-proof (ZZ) type with stamped steel plate to block solid dust; oil-proof (2RS) contact seal prevents grease leakage and resists moisture.

•Strong Adaptability: Various structures and clearance grades fit different speed, temperature and environmental working conditions.

2. Product Classification

•By Row Number: Single row series (6 series), Double row series (4 series)

•By Sealing Structure: Open type, ZZ dust-proof sealed type, 2RS oil-proof sealed type
