10x F4-9M Miniature Planar Bearing Micro Thrust Axial Ball Bearing 4x9x4mm

"Specifications: Color:silver,yellow Weight:14g Material: bearing copper, steel Model: F4-9M Inner diameter: 4mm Outer diameter: 9mm Thickness: 4mm Package list: 10 x Bearings Ring 10 x Washers Ring 10 x Rolling Ring Note: The material of the cage is copper. The plane thrust ball is a separable bearing with a contact angle of 90. It can be installed separately and can only bear axial load. The thrust bearing has a low limit speed, and the steel ball is centrifugally squeezed to the outside of the raceway, which is easy to scratch, but is not suitable for high speed operation. The one-way thrust bearing can withstand one-way axial load, the two-way bearing can withstand two-way axial load, and the thrust ball bearing with spherical race has self-aligning performance, which can eliminate the influence of installation error."
