PB Series small pneumatic cylinders

Complies with JIS standards
Belongs to the mini/compact cylinder category; features a compact structure, small size, and light weight.
The piston rod offers high guidance accuracy, and the guide bearing requires no additional lubrication.
Cylinders with 4mm and 6mm bores can only be mounted via the front cover, whereas cylinders with 10mm, 12mm, and 16mm bores can be mounted via either the front or rear cover.
The piston rod and cylinder barrel are made of stainless steel, enabling the cylinder to operate in mildly corrosive environments.
With a small bore and rapid response, it is suitable for high-frequency operating environments.
The PBR series mini pen-style cylinders feature mounting holes in the front and rear caps, allowing for direct mounting without the need for additional mounting accessories.

PB Series small pneumatic cylinders consists of miniature pen-style cylinders featuring a slender, pen-like profile and a stainless steel barrel and piston rod. Compact in size and capable of high-frequency reciprocating motion, they are the standard choice for short-stroke, precision pushing and lifting applications.

Various mounting accessories: FA front flange, LB axial mounting bracket, and CJ foot mount.

Standard front-cover mounting is used, but front-cover mounting types (PSBR, PTBR) are also available as options.

Multiple rear cover configurations are available: CB (double clevis), U (radial air inlet), and R (axial air inlet).

Various cylinder specifications available:
PB Pen-type cylinder (double-acting)
PSB Pen-type cylinder (single-acting, push type)
PTB Pen-type cylinder (single-acting, pull type)
PBD Pen-type cylinder (double-rod, double-acting)
PBJ Pen-type cylinder (double-rod, double-acting, adjustable stroke)
PBR Pen-type cylinder (double-acting, front-cap mount)
PSBR Pen-type cylinder (single-acting, push type, front-cap mount)
PSBR Pen-type cylinder (single-acting, pull type, front-cap mount)
