SMC KJ20D, Piston Rod Ball Joint 80 mm, 100 mm

The SMC KJ20D is a piston-rod ball-joint accessory engineered for the C96/CP96 series ISO cylinders with 80 mm and 100 mm bores. Its construction uses a precision-hardened chrome-plated bearing steel inner and a fluororesin liner for built-in, lubrication-free movement. Designed for use in automation systems, the KJ20D ensures smoother rod movement, reduced side-loads on cylinders, and extended mechanism life.

Standout Features and Benefits of Choosing the SMC Piston Rod Ball Joint

• Spherical bearing design allows self-centring movement and reduces lateral stress.
• Compatible with 80 mm and 100 mm bore cylinders (C96/CP96 series).
• Hard-chrome plated bearing steel materials ensure wear resistance and durability.
• Fluororesin liner enables smooth operation without additional lubrication.
• Allows an allowable inclination angle of up to 19° (model-dependent) for flexible mounting.
• Compact design supports tighter installation spaces in automation setups.

Reliable Motion Control

This ball-joint rod end improves alignment and absorbs side loads in pneumatic cylinder systems. By decoupling rod misalignment from angular loads, it improves the service life of the cylinder and the mounted mechanism. Its robust materials and lubrication-free liner reduce both maintenance overhead and downtime.

Wide Application Range

• Industrial automation equipment.
• Material-handling systems.
• Packaging machines with rod extensions.
• Robotics or pick-and-place frames.
• OEM machine builds where ISO-standard cylinders (C96/CP96) must meet extended service-life demands.
