CJT Series Standard Hydraulic Cylinders (7/14/21 MPa)

CJT Series Standard Hydraulic Cylinders (7/14/21 MPa)

Excellent low-speed performance with high motion accuracy.

Smooth cushioning effect.

Product Description

Designed to meet the wide-ranging needs of general industrial machinery, especially machine tools, the CJT series offers a variety of mounting types.

The cushioning mechanism has been specifically improved to achieve minimal cushioning impact and smooth stopping performance.

Additionally, a version with a sliding proximity switch mounted on the cylinder body is available, enabling easy position detection. This CJT series with proximity switch has been fully standardized.
