Installation and Maintenance

1.NYD Backstop mainly used to prevent conveyor or pump running reversely in low-speed .

2.Before installation, be sure the inner race rotation direction ( direction of arrow marked on the inner race) conforms to the conveyor belt rotation direction.

3.Install the torque arm of backstop tightly by using a 11T or higher grade bolt. Please be sure torque arm surface is aligned with the side of outer race and free from any dust.

4.Recommended shaft tolerance is h7 or h8.

5.When mounting the clutch onto the shaft, apply pressure to the outer race only. Do not use a hammer to beat inner race, outer race ,or dust cap directly. No any force put to the dustproof end plate .

6.Use only a parallel key to secure the clutch to the shaft. Do not use a tapered Key.

7.When mounting NYD160 or larger size clutch ( Grease lubrication type),place one of the two oil holes at the bottom. It is convenient to discharge the grease and clean the clutch.

8.When shaft rotates, the end of the torque arm would move to some direction. Limiting the torque arm only in the rotation direction, but be sure there is some space for torque arm to rotate freely. The inside clutch would be warped if torque end is fixed completely. And it would damage the elements .

9.The backstop clutch torque arm is standard ones.

Lubrication

NYD95-135 are delivered with grease, no need more maintenance; NYD160-450 use oil lubrication, need to be changed every two years. When adding oil, loosen the outer race rings, open the bottom oil hole bolt, let the oil out, then add oil by ring hole.
