E25 Series

Boston Gear E25 Series, stainless steel body, disposable air cylinders have been designed using materials specifically selected

for optimum performance and long service life! Each component is precision machined, assembled and tested for exacting quality

standards using state-of-the-art equipment and cylinder technology.

The E25 Series cylinders are dimensionally interchangeable with many other manufacturers. See guide on pages 38 & 39.

Material Specifications

1. HEAD/CAP: Precision machined from 2011-T3 solid aluminum alloy for strength and durability. “V” grooves in the face of the

head and cap provide maximum air flow for fast response.

2. CYLINDER BODY: Type 304 stainless steel with a drawn and polished internal diameter which ensures smooth performance

and outstanding cycle life. The body is secured to the head and cap using double rolled in construction.

3. PISTON ROD: Type 303 stainless steel which is hard chrome plated, ground and polished for extended rod seal life; nonrotating

rod cylinders use a carbon steel piston rod.

4. ROD THREADS: Roll-formed for superior strength and resistance to wear or breakage.

5. WRENCH FLATS: Broached wrench flats are standard on most models.

6. PISTON: Solid aluminum alloy (2011-T3) which is strong yet lightweight for low inertia. The piston is spin riveted to roll formed

piston rod threads for maximum strength.

7. PISTON SEALS: Lip type nitrile seals are pressure energized and wear compensating. Excellent lubricant retention characteristics

reduce seal friction, ensuring long life.

8. BEARING: Oil impregnated sintered bronze provides exceptional rod support, smooth rod movement and optimum cycle life.

9. ROD SEAL: Lip type nitrile which is pressure energized and wear compensating.

10. PRESSURE PORTS: Full, unrestricted porting for maximum air flow.

11. SPRINGS: The springs used on single acting models are manufactured from music wire and are designed for literally
