6001 Single Row Deep Groove Ball Bearings Generation C, Open Design
The 6001 Miniature ball bearings are widely used in precision equipment with stringent space and precision requirements, such as: medical devices (dental handpieces, miniature pumps), precision instruments (flow meters, encoders), robots (miniature joints), optical equipment (camera focusing mechanisms), miniature motors, and aerospace precision instruments.
The 6001 bearing is a Single row deep groove ball bearings Generation C, open design with an inner diameter of 12 mm , an outer diameter of 28 mm, a width of 8 mm. It typically uses Class6 (P6) grade precision tolerances and GCr15SiMn rings, Its dynamic radial rated load is approximately 5855 N, its static radial rated load is approximately 2317 N. It uses CN standard radial clearance, Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The 6001 Miniature ball bearings primarily consist of thin-walled inner and outer rings (precision machined), tiny steel balls (typically less than 3mm in diameter), and a cage (stamped steel or one-piece plastic). The most common type is the deep groove ball bearing, available in open, dust-covered, or sealed configurations, with inner diameters typically ranging from 1mm to 10mm.
Miniature ball bearings are small and lightweight, making them suitable for extremely compact spaces. They offer high rotational accuracy, reaching P4 level or higher, with smooth operation and low frictional torque. They exhibit significant low noise and low vibration characteristics, and some models feature a dustproof design to effectively prevent the intrusion of tiny particles, resulting in a long service life.
