PB-K Backstop Clutch Precision Formed Cams High Torque For General Purpose
Production introduction
1. PB-K Series clutches feature precision formed cams which
provide higest torque capacities with excelent wear life.
2. Do not use the PB clutch as a coupling
3. Specify right(R.H) or left hand (L.H) inner race drive(not free)
viewed from direction of arrow mark when ordering.
4. Model PB5K~PB14K Series have 3 pcs of filler except PB-3K
which has one only.
5. These units can be operated in ambient temperature
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.
