Product summary
618/7: miniature bearing, brand SKF. Bore diameter d 7 mm, outside diameter D 14 mm, width B 3.5 mm. Dynamic load rating C 0.956 kN, static load rating C0 0.4 kN, limiting speed 63 000 rpm, weight 0.002 kg.
The same principle as a deep groove ball bearing, in sizes from tenths of a millimetre.
Where it is used
Micro motors, cooling fans, encoders and sensors, medical and dental instruments, hand-held power tools, feed drives, precision positioning mechanisms. Often made of stainless steel or with ceramic rolling elements for humidity and high speeds.
When not to use
Do not select by the bore diameter alone: metric and inch series sit side by side in this class (for example 6.35 mm and 6.00 mm). A mistake gives either an interference fit that jams the bearing and takes up its clearance, or a ring that creeps on the shaft.
