F Series 7•14MPa
Tie Rod Type Cylinder
FEATURES :
● Excellent Dependability
The sliding part of the rod is of high-quality chrome-plated construction and a soft bronze casting is
used for the rod bushing to prevent scarring of the rod with high performance U-shape packing used as
the rod packing. These features provide reliability and durability while protecting against oil leakage.
● Perfect Cushion Construction
Tapered cushion construction is incorporated into our standard cylinders and results in an approximate reduction of 50% of surge pressure as compared to conventional cylinders. This cushion construction provides ideal smooth stoppage over a very short time.
● Switch Adjusted
Our high-performance reliable dustproof switches (magnetic proximity switches) are standard. Because of their unified compact construction, there is no need to attach external sensors, thereby making cylinder installation very efficient.

K Series 3.5MPa
Tie Rod Type Cylinder
FEATURES :
● Excellent Dependability
The rod is prevented being damaged by using a soft high-strength brass on the rod sliding
surfaces for the chrome plating and rod bush of the high quality. An efficient U packing was adopted in Rod Packing. The gasket with the back pressure prevention ditch was adopted in piston packing. High reliability and durability to the oil leakage have been achieved.
● Certain, steady operation
The piston uses a wear ring to prevent seizure, ensuring improved reliability. The cushion mechanism provides high accuracy, enabling reliable operation. Back-pressure preventive grooved packing is used for the piston packing.
● Switch Adjusted
As a standard feature, the KR series is equipped with the reliable high-performance switch (magnetic proximity switch), which provides excellent dust-proof structure. The compact, integrated structure enables efficient installation of the cylinder, without necessity of an external detector. With the LED indicator lamp, you can easily check operating status.

T Series 21MPa
Tie Rod Type Cylinder
FEATURES :
● Excellent Dependability
To prevent damage to the rod, the rod sliding surface is plated with high-quality chromium, and soft high
strength brass is used for the rod bush. Also, high-performance U-packing is used for the rod packing .
Back pressure preventive grooved packing is used for the piston packing. Thus, the T-series provides high reliability against oil leak and durability.
● Certain, steady operation
The piston uses a wear ring to prevent seizure, ensuring improved reliability. The cushion mechanism provides high accuracy, enabling reliable operation.

C Series 10•14•16•21MPa
Compact Type Cylinder
FEATURES :
● Easy Maintenance
The packing can be changed by simply loosening the rod bushing without having to remove the main unit or disconnecting lines – the ultimate in easy maintenance
● Innovations that make installation a breeze
The attachment holes have been recessed to hide the cap bolts in the cylinder main unit. They can be attached from either the front or the rear. A parallel key has been attached in the Foot type, thereby eliminating the need for positioning.
