68 series bearings
68 series bearings were developed for applications where space limitations are of the utmost importance. For example, with the development of humanization design, more and more application for people need smaller and lighter, the difference between the inside and outside diameters of the rings has been minimized or thinned out. Of course this comes at a price by compromising load capacities compared with standard deep groove ball bearing. However, these bearings still accommodate a relatively light radial thrust or combined loads to reach the requirement of application conveniently.
The know-how and the advanced machines used in manufacturing allow our Bearings to reach thin dimensional limits. Our Thin section bearings facilitate the compact design of industrial robots, electrical tools, motor, electrical home appliance, automotive industry, audio-visual and office automation equipment.
