Product description
High Reliability
ERSK linear shaft has very stringent quality control standards covering every production process. With proper lubrication and use,trouble-free operation for an extended period of time is possible.
Smooth Operation
The high efficiency of linear shaft is vastly superior to conventional shaft. The torque required is less than 30%. Linear motion can be easily changed from rotary motion.
High Durability
Rigidly selected materials, intensive heat treating and processing techniques, backed by years of experience,have resulted in the most durable linear shaft manufactured.
