608 Miniature Deep Groove Ball Bearings are widely used micro bearings for small transmission equipment. With a standard size of 8mm inner diameter × 22mm outer diameter × 7mm width, the 608 bearing is a universal replacement bearing for various small equipment applications.
Available types include 608 OPEN (open type), 608ZZ (double metal shield), and 608-2RS (double rubber sealed). The bearing is made of GCr15 high carbon chromium bearing steel (equivalent to 100Cr6 steel), with a stamped steel cage for stable operation and deformation resistance.
Standard production uses P0 precision grade, with P6 precision high-speed versions available for customization. The bearing features standard clearance, low friction, high-speed rotation, and excellent compatibility.
Product Applications
608 OPEN (Open Type)
The open design has no dust cover or sealing ring, providing better heat dissipation and higher rotation speed. It is suitable for clean indoor environments, dust-free equipment, and precision high-speed transmission systems. The design also allows convenient secondary grease lubrication.
Common Applications
● Small motors and transmission equipment
● Precision mechanical devices
● Rollers and rotating components
● High-speed small equipment
● Various OEM replacement applications
Product Functions and Advantages
● High precision and low noise
The 608 bearing supports P6 precision grade with noise performance up to Z4V4, providing smooth and quiet operation for equipment requiring low noise performance.
● High-speed and stable rotation
The deep groove ball structure reduces friction and running resistance, ensuring smooth rotation without vibration or abnormal noise.
● Durable GCr15 bearing steel
Heat-treated GCr15 material provides high hardness, wear resistance, anti-fatigue performance, and long service life for continuous operation.
● Compact size and easy installation
The 8×22×7mm miniature design saves installation space and fits a wide range of small equipment.
● Maintenance-friendly sealed design
ZZ and 2RS versions are pre-lubricated with long-life grease, providing dust and moisture protection and reducing maintenance requirements.
