Make sure that lubrication is essential for universal joint operation. Generally the most appropriate and safest way is to equip a joint boot with oil pack in it. Ensure lubrication especially in its early period of operation to prevent initial seizure.
| Lubrication Method | Remarks |
|---|---|
| Dropping or applying oil | Periodically or at a timing when it is needed |
| Joint boot | Grease or oil enclosed Recommended brand ●Oil Tellus (Shell)） FBK oil (Nippon Oil Corporation) Mechanic oil (Idemitsu) |
| Oil pack | ●Molybdenum disulfide oil (prepared by Miyoshikikai) ●Oil pad ●Joint boot Lubrication with above products is prepared. |
| Lubrication Method | Remarks |
|---|---|
| Oil mist spray method | |
| Oil bath method | |
| Grease filling K、KD(20～30） ＫＬ、ＫＦ、ＫＦＤ |
Guideline is; once a month for over 500/min application and once every other month for under 500/min application. Increase filling times of grease for applications at large torque fluctuation, frequent forward-reverse rotational change, or continuous operation.

High Speed Revolution
High speed revolution might become a possible cause to shorten the joint life. If the circumferential velocity of joint outer diameter is more than 0.15m/s, apply forced-feed lubrication or the one with oil pack
