Three-point contact, shake tentacles pass
Reverse death, guide is spline style,||t The bearing can be preloaded with load, and can be used as a radial follow-up bearing. Each variable speed bearing has a retractable ball. The bearing can do reciprocating and rotating motion at the same time. The ball does not retract, the travel is limited, the seat is high, the storage system efficiency is low, and it can withstand medium loads. The outer shell is a composite bearing with high precision and good performance. It is often used in stamping this guide. The linear bucket usually has a limited stroke, the ball does not travel in a circular motion, and can bear medium loads. The fluid body and the guide shaft and the outer stage are all in contact with each other, with large bearing capacity, good rigidity, and can be used for straight or straight motion. The rolling body is a recirculating ball surface bearing, which can be used for linear and reciprocating motion, with unlimited stroke, and can bear strong, light, and medium loads.TR/T 10835-2002
