- 1. Do not use oil that contains EP additives.
- 2. In the case of the above grease lubrication, the operating ambient temperature range in which the cam clutch can function properly is -5°C to 40°C. For temperature conditions exceeding this, please contact us.
- 3. Genuine lubricating oil (grease) for cam clutches is available, so please use it.
| Genuine lubricating oil (grease) | capacity | Application |
|---|---|---|
| Genuine lubricating oil for cam clutches | 1L | Overrunning or Backstop Applications (1/3 or less of allowable rotation speed ) |
| Genuine lubricating oil for cam clutches (For indexing applications ) |
1L | Indexing |
| Genuine lubricating grease for cam clutches | 500g | Ambient operating temperature -5℃～40℃ |
Lubrication type and maintenance
For oil lubrication series, lubricant is not included at the time of shipment, so please apply the appropriate lubricant before use.
| Series | Lubrication method | Maintenance | |
|---|---|---|---|
| MZ・MZ-G・LD MA・BB・ML |
Grease lubrication | Grease is pre-filled at the time of shipment. When using BB series with oil lubrication, use an oil bath and the oil level height should be above the shaft center. | |
| 200・PB | Grease lubrication | Clean the inside once every 6 months and replace with new grease. | |
| Oil lubrication | Lubricate oil bath type. Change the oil every three months. | ||
| MG・MI・MI-S・MR | Oil lubrication | Refill the oil every 100 hours, and once every three months drain the old oil, clean the inside, and then replace with new oil. | |
| MX | Oil lubrication | Every 300 hours, drain the old oil, clean the inside, and replace with new oil. | |
| MG-R | Oil lubrication | Refill every 300 hours, and once every three months drain the old oil, clean the inside, and replace with new oil. | |
| BR | Package Type | Grease lubrication | Grease is pre-filled at the time of shipment. Refill every 3 months. |
| Open type | Grease lubrication | Refill every 3 months. | |
| Oil lubrication | Once every six months, drain the old oil, clean the inside, and then replace with new oil. | ||
| BS | 30～135 | Grease lubrication | Grease is pre-filled at the time of shipment. |
| 160～350 | Grease lubrication | Once a year, drain the old grease, clean the inside, and then inject new grease. | |
| 425, 450 | Oil lubrication | Refill every 3 months, and once every 6 months to 1 year, drain the old oil, clean the inside, and replace with new oil. | |
| Cam Clutch Boxes | Oil Bath Screw pump and impeller Screw pump and oil bath External forced lubrication |
We will discuss the details when specifications are finalized, but in general, no maintenance is required for one year. | |
Lubricant injection method
1. How to lubricate the MG, MR series
- 1. In principle, the amount of lubricant should be up to the height of the shaft center for overrunning and backstopping.
- 2. The outer race of each series has 2 to 4 plugs.
- 3. For those with four plugs available, place each plug in the top, middle, and bottom positions, remove the top and middle plugs, oil from the top, and fill until oil comes out of the middle plug.
- 4. For those with three plugs available, one plug should be at the bottom and the top two plugs should be removed and oiled from one of them. Rotate either of the upper plug positions to the height of the shaft center to check the oil level.
- 5. For those with only two plugs, remove only the upper plug and refuel from that plug. Further rotate the plug 90° and check if oil has entered up to the shaft center.
2. How to lubricate the MI, MI-S, MX series
- 1. Fill the tank almost to full capacity.
- 2. There are plugs on the outer circumference or on the side.
- 3. For those that have 3 or 4 plugs available on the outer circumference, tilt the plug position slightly and oil the plug until oil comes out of the adjacent plug.
- 4. For those with two plugs available, insert the tip of the oil jug into the plug and oil the plug until it overflows with oil.
- 5. For those with side plugs available, open both plugs with the side with the two plugs side by side facing up, fill with oil from one side and fill until it spills from one side.
3. How to lubricate the MG-R series
- 1. In principle, the amount of lubricating oil should be up to the height of the shaft center. Check with the round oil level gauge attached to the oil reservoir.
- 2. The outer race has 4 to 3 plugs Install one of them directly below so that it can be used as an oil drain plug. Also, oil should be supplied through the oil supply plug in the oil reservoir. Therefore, install the oil reservoir so that the oil feed plug is positioned directly above.
4. Special lubrication methods
When cam clutches are used inside machinery and equipment, special lubrication methods are required because normal maintenance is difficult. An example is shown on the left. This method provides a through-plug on the shaft for forced lubrication through the rotor seal.
