KIM developed the SG Type Roller screw consisting of a shaft, nut, roller, etc., and has the largest diameter among existing roller screws.

KIM provides an eco-friendly energy solution through the use of an electric mechanical actuating system which is an alternative system of an hydraulic system.
An hydraulic system usually requires a number of additional facilities, but our roller screw makes the system drive compactly with a motor and a roller screw. 

In particular, the roller screws has strengths in high load, precise operation, and fast speed, so it can be used in the marine drilling industry as a product that can withstand more than equal loads compared to hydraulic systems.
