1. Prelubricated with special grease
2. No lubrication maintenance required.
3. Easy installation and handling
Type PB 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.
Specify right (RH) or left hand (LH) inner race drive viewed from the end marked by the arrow.Check if the rotation of the clutch is correct before being run-in.
Key to be used should be in accordance with JIS B1301-1959. 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.

Installing the PB CAM Clutch correctly is imperative for optimal performance and longevity. The installation process involves several key steps, each requiring careful attention to detail.
1. PB Series Cam Clutch is used for inner race overrunning applications. PB Series Cam Clutch is used for indexing applications.
2. For attaching a pulley, a gear, or sprocket to the clutch, insert the clutch into the hub of the device, and screw the bolts (high tension) into the tapped holes on the clutch end. The tolerance bore of the hub should be H6 or H7 of JIS standard.
3. Recommended shaft tolerances are as follows:
4. The key should be in accordance with JIS B1301-1959. However, for PB and above models, a key is attached.
5. Use only a parallel key to secure the clutch. Never use a tapered key.
6. If the clutch receives shock loads or is designed for use at full torque capacity, it is better to use a hardened key and shaft.
7. Allow for a clearance between the top of the clutch keyway and the top of the key for pressure ventilation of the clutch in the case of PB Series. A pressure ventilation hole is provided on the keyway of the clutch inner race.
8. When mounting the clutch on a shaft, apply pressure to the inner race, but never to the outer race .
9. Thrust load should be taken up by other devices, not by the Cam Clutch.
10. When using PB Series at medium and high speeds, pay attention to heating. Longevity is shortened if the temperature of Cam Clutch outer race rises to over 70°C. In case of continuous over running Please contact SUMA. In this case, use a different model or provide an oil bath or forced lubrication.
11. Oil is not sealed in at the time of shipment. Supply an appropriate amount of oil before use.
12. When placing an order for PB Series Cam Clutch model PB5 and above, please inform SUMA of the overrunning speed you use.
13. For vertical mounting, please consult SUMA.
Ensuring secure fastening of the PB CAM Clutch to the shaft or mounting surface is vital. Incorrect or loose fastening can lead to misalignment, reducing the clutch's effectiveness and potentially causing damage to both the clutch and the machinery.
Utilize solely a parallel key for securing the clutch to the shaft, avoiding the use of a tapered key.
When installing the clutch onto the shaft, exert pressure on the inner race exclusively, avoiding any pressure on the outer race. Refer to the illustration on the right for guidance.
For vertical installations, kindly seek guidance from SUMA TEAM .
Select a key that adheres to the specifications outlined in ISO R773 (DIN 6885.1).
Regular maintenance is paramount to prolonging the life of the PB CAM Clutch and maintaining optimal performance. Implementing a proactive maintenance schedule involves several key practices.
Prelubricated with special grease, No lubrication maintenance required.
The operating environment can significantly impact the performance of the PB CAM Clutch.
Factors such as temperature, humidity, and exposure to contaminants can influence the clutch's effectiveness. Implementing measures to mitigate these environmental factors, such as installing protective covers or seals, contributes to the longevity of the clutch.
The permissible temperature range is between -5°C and 40°C.
