Product detail


1. Low noise

2. Self locking

For the place require for minor holding force, save the cost of baking device, such as in slope conveyor.

3. Fast stop

The ordinary gear reducer available in market requires 5-10 seconds stop time. But NRV series product need only 2-5 seconds to reach state of still.

4. High accommodation

You may select from hollow shat, uni-direction output shaft or dal output shaft, easy to modify, only one ninute to complete the dissemble and assemble of shat.

5. High safety

Use transmission different from conventional method, no sprocket pulley is needed, no exposed transmission structure, reduce the possibility of operator.

6. Good protection

Water, dust proof, the protection class P55 possesses, good isolation to dust and moisture.

7. Allow multiple sides installation, no restriction in angle

8. Good cooling effect

One formation aluminum alloy for casing, quick heat dissipation extended life for worn lever, worn gear, good durability (worm-casing during running is normal )

9. Easy maintenance

Different from conventional mounting method, you need not the dissemble the sprocket, pulley but only dissemble mounting base of the reducer to complete the modification easily.

10. No restriction on brand

Match with 15W-20W panes or domestic product available in market without further processing.

11.Occupied no space

The space requirement for the installation of output shaft is considerably large while assembling motor or red of hollow type reducer may form right angle with motor, thus facilitate miniaturize of the machine.

Gear ratio:7.5, 10,15, 20, 25, 30, 40, 50, 60, 80, 100

Weight without motor: 1.2kg
