Standardized Bladders Simplify Design

Aug. 5, 2004
The Pneuma-Seal line of inflatable elastomeric bladders has been standardized to simplify the design and fabrication of devices using pneumatic actuators and seals.

STANDARDIZED BLADDERS SIMPLIFY DESIGN

The bladders come in lengths of 6, 9, and 12 in. with two-day delivery. Width is 1.25 in. and uninflated thickness is 0.625 in. Fully inflated, they are 1-in. thick, providing a 0.375-in. range of motion. All sizes have a 6-in. flexible-hose air connection terminated by a 1/8-27-NPT

pneumatic fitting. Rated service temperature range is 25 to 250°F. Chemical resistance is the same as for EPDM. The bladders have been life-tested to 500,000 cycles at room temperature. All bladders are either unsupported or premounted in protective aluminum housings. Unsupported bladders provide soft, conformal clamping and sealing for applications ranging from workholding to material handling and cargo stabilization. Supported bladders provide “hard” mechanical actuation force, yet compensate for variations in alignment or clearance. Maximum rated pressure is 25 psi. They can be held in position with fitted housings or any EPDM-compatible adhesive.
