PB Sprag Type Overrunning Cam Clutch
Production introduction
A spherical plain bearing is a spherical plain bearing. Its sliding contact surface is an inner spherical surface and an outer spherical surface. It can rotate and swing at any angle during the movement. It is made by various special processing methods such as surface phosphating, pits, pad embedding, and spraying. The spherical plain bearing has the characteristics of large bearing capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubricity, etc
Installation
1. Concentricities of the inner race and the outer race are maintained by the plain bearing located between the outer race and the shaft. Radial load which works on the outer race is also supported by this plain bearing. The shaft must therefore be extended through the clutch outer race end.
2. Specify right (RH) or left hand (LH) inner race drive viewed from the end marked by the arrow in the illustration Above.Check if the rotation of the clutch is correct before being run-in.
3.Key to be used should be in accordance with JIS B1301-1959
4.The bore of the driven member, such as the sprocket on the clutch outer race, should meet H6 or H7 tolerance of the JIS standard.
5. For indexing use, oil lubrication is recommended.
