Star Flex ALS-R (ALS-055-R-18B-20B)

Star Flex ALS-R ALS-055-R-18B-20B

MIKI PULLEY

MIKI PULLEY

Element hardness 97JIS A used, designed to use preliminary compression with no backlash. Supports a wide range of applications, from simple servo to general purpose motor with high torque.

[Features]
· Polyurethane elastomer used for element. So, the transmission torque is more than twice that of conventional jaw coupling.
· Design to distribute pre-compression, and so can be used with no backlash. (ALS-Y/R type)
· Power transmission through polyurethane elastomer with rubber elastic force. It has excellent vibration and impact absorption.
