Chicago Dryer Air Cylinder, B490 x 3" Stroke, #3 Rod, 3/8-16 – 263290

The 263290 Air Cylinder is a Chicago Dryer pneumatic linear actuator identified as B490 series with a 3″ stroke and #3 rod configuration threaded 3/8-16. This air cylinder is used in flatwork ironer and folder assemblies where controlled linear motion is required for positioning, clamping, or transfer mechanisms.

The 3″ stroke provides mid-range travel, while the 3/8-16 threaded rod end supports direct mechanical linkage attachment. Proper bore size (B490 series designation), rod thread specification, and mounting configuration must match the existing installation to maintain correct actuation force and mechanical timing.

Maintenance Tip: Confirm rod thread engagement depth (3/8-16) during installation to prevent stripping or linkage misalignment.

CICUS supplies field-matched pneumatic motion components engineered for commercial flatwork ironer systems.
