Industry's First! (Patent no. 5578502)
The function of a shock absorber is built in a speed controller. Two-stage exhausting flow rate adjustment make the same control as a cylinder with a shock absorber possible.
No more cylinder mounting type shock absorber is necessary.
Two-stage exhaust flow rate adjustment is realized. By using 2nd stage exhaust speed to be as cushion (brake), controlling like a shock absorber is possible.
Speed control (EX1), shock absorbing (cushion) strength (EX2), and start timing of shock absorber (TIM) are separately adjustable.
e.g. Keeping a same cycle time for a cylinder with a shock absorber, however the shock can be reduced to 1/9.
Durability is about 3 times of a cylinder mounting type shock absorber.
Durability of BJSU is more than 3 times of a normal shock absorber, which is directly mounted on a cylinder. Thus, reducing the cost and the frequency of the maintenace are possible in long-run operation.
