(1) The data is suitable for the on-off frequency less than 1000 cycles per hour.
If your system is over 1000 cycles per hour, please contact us.
(2) 1000 times during the service life.
(3) Applied to the output shaft center at a speed of 100 rpm.
(4) Noise level measured of ratio 5, input speed 3000 rpm, distance 1m, and idle running.
* If your system operates 24hrs per day, please contact us.
* If the ratio you need is not included in our catalogue, please contact us.
