Instruction manual - MN·MKN

About installation

Follow the instruction and note below to accurate installation of Mecha-lock.

Use the torque wrench for tightening screws.

Cleaning of Mecha-lock installation surface.

Wipe and clean the dust, rust and oil on shaft surface.
Spread the oil (operation oil 68) to shaft surface and bore of hub.

Do not use the oil which includes molybdenum and silicon due to reduce the grip of friction.


For normal application

Wipe the rust protection oil, which used at packaging before assembly. (MN)


How to increase the torque capacity.

Transmission torque can be stable by using recommended oil.
Spread the oil at the location below.

Recommended oil spreading location by ISEL.
·Out side of outer diameter.
·Taper part of inner ring, and outer ring.
·Screw head and screw of locking screw.


Note for clean circumstance application

·Circumstances is vacuumed.

  1. Application of dry condition without oil.
    Torque capacity will not be the same with catalogue without oil.
  2. Application of using vacuum grease.
    This grease may cause of shaft slipping or increasing the tightening toque, which over the yield point. Therefore we recommend of evaluation test.
This grease may cause of shaft slipping or increasing the tightening toque, which over the yield point. Therefore we recommend of evaluation test.
For the application of food industry machines, cleaning the oil may cause of the decreasing the transmission torque with stainless type.


Note for shaft installation.

The inner ring taper and outer ring taper are stacking together by transportation and hard to insert the shaft and hub, loose the locking screws and disassemble the taper pats of Mecha-lock by using uninstallation screw.


Amount of hub movement in shaft direction.

The hub moves by tightening the nut in Mecha-lock MN·MKN series due to their construction. Refer to move amount in table.
Amount of hub movement in shaft direction.


After installing Mecha-lock, confirm the hub edge perfectly attached to the nut and the shaft goes thru the Mecha-lcok. (Fig.1). Adjust the location and tighten gently by hand.
Tightening the nut lightly after positioning. And tighten again by torque wrench with certain torque. Finally, confirm that nut does not rotate after tightening.

If the installation is difficult by rotating together with shaft, fix the hub side first then turn the nut by hand to make no gap. Finally start tightening with torque wrench.

Uninstallation

Check your safety first before starting an uninstall operation.
Check thrust load or torque are not on Mecha-lock or check the drops.

Hub and nut connection will be unlocked by loosening 2 nuts. Outer ring will move to the nut and connection of outer and inner ring will be separated.
