MG/MI700 Cam Clutch: Engineered for High-Performance Overrunning and Indexing

In high-demand industrial power transmission, the MG/MI700 cam clutch serves as a critical component for systems requiring precise overrunning, indexing, and backstopping capabilities. Manufactured by LST Sprag Clutch, the MG/MI700 is engineered to provide consistent torque transmission and reliable protection against reverse rotation in heavy-duty machinery.

Core Functionality: Overrunning and Indexing

The MG/MI700 is designed to facilitate seamless transitions between driving and free-wheeling states. In overrunning applications, the clutch allows the driven member to rotate freely at speeds higher than the driving member, protecting motors and gearboxes from damage. For indexing applications, the clutch converts reciprocating motion into intermittent rotary motion with extreme precision, making it essential for automation lines, packaging machinery, and textile equipment.

Project Support and Procurement

At LST Sprag Clutch, we understand that standard parts do not always meet every unique site requirement. We offer:

• Stock Availability: Standard series (AV, ASNU, MG, MZ, FSO, BS, TFS, DC, BWC, RSBW, CSK, HF, HFL) are maintained in stock for rapid dispatch.
• Customization: If the MG/MI700 does not match your specific space constraints or load requirements, we offer non-standard size manufacturing.
• Lead Time: Optimized supply chain management ensures a standard lead time of one week.
• Sampling: We provide samples for validation purposes (freight collect).

Frequently Asked Questions (FAQ)

1. What are the lead times for non-standard MG/MI clutch sizes?

While our standard models are kept in stock with a one-week lead time, custom non-standard sizes require a tailored production schedule. Contact our engineering team with your specific dimensions for a refined timeline.

2. Does the MG/MI700 series require specific lubrication?

Proper lubrication is essential for the longevity of all cam clutches. Please refer to the technical manual provided with your order for specific oil/grease compatibility based on your rotational speed and duty cycle.

3. Can you provide custom manufacturing for small batches?

Yes, LST Sprag Clutch specializes in both high-volume supply and custom non-standard configurations to meet the unique structural requirements of your machinery.

Installation and Usage
MG Series Cam Clutch is used for inner race overrunning applications. MI Series Cam clutch is used for indexing applications.
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. See the installation illustration on page 70.
Recommended shaft tolerances are as follows:
The key should be in accordance with JIS B1301–1959. However, for M750 and above models a key is attached.
Use only a parallel key to secure the clutch. Never use a tapered key.
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.
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 MG Series. A pressure ventilation hole is provided on the keyway of the clutch inner race.
When mounting the clutch on a shaft, apply pressure to the inner race, but never to the outer race.
Thrust load should be taken up by other devices, not by the Cam Clutch.
When using MG 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℃. In case of continuous over running Please contact Tsubaki. In this case, use a different model or provide an oil bath or forced lubrication.
Oil is not sealed in at the time of shipment, Supply an appropriate amount of oil before use.
When placing an order for MG 750 and above, please inform TSUBAKI of the overrunning speed you use.
For vertical mounting, please consult LST company.
