CLA CONSTRUCTION

PISTON RODS are

1

/4" or 5/16" diameter on all CLA cylinders dependent on bore size. They are super-finished stainless steel for maximum corrosion resistance.

CYLINDER TUBES are high-tensile aluminum alloy tubing, hard anodized finish.

PISTONS are aluminum, secured by a roll pin. HEADS are accurately machined from aluminum bar stock. SPRINGS employed in the spring return models exert the

following forces to return the piston and rod: The

3

/4" bore models have a spring which exerts a 4 lbs. force as installed and a 9.4 lbs. force when compressed by stroke. The 11/8" bore models rate is 51/2lbs. installed and 9 lbs. compressed. All spring forces are approximate.

BRONZE BUSHING oil impregnated, for good lubrication and long life.

CYLINDER ASSEMBLY is held together with high-tensile steel tie rods. This is recognized by industry to be the best way to provide pre-stressed construction for rough service.

ROD SEAL is a self-adjusting modified U-cup. PISTON SEALS are self-adjusting modified U-cups. TUBE SEALS are flat gaskets, retained type, to prevent any

possible extrusion. PORTS are

1

/8" N.P.T.

MOUNTING may be accomplished by attaching the head, the cap, or side mounting by holes provided in the universal mount. Tie rod holes tapped thru 8-32 or 10-32 for face mounting. Pivot or clevis mount may be made by attaching brackets with cap screws provided (See Accessories Brochure). Stud may be threaded into mounting plate, or secured by use of jam nut provided.

CLH CONSTRUCTION

PISTON RODS are of adequate size, of approximately 100,000 psi yield steel. They are ground, polished and hard chrome plated for maximum wear and corrosion resistance. Wrench flats are standard.

CYLINDER TUBES are high-tensile aluminum alloy with hard anodized finish.

PISTONS are steel for strength and wear resistance, fastened to the rod by a self-locking nut.

HEADS are cold rolled steel to provide best strength characteristics and black oxided for corrosion resistance.

SPRINGS employed in the spring return models exert the following forces to return the piston and rod: Installed force is

12.8 lbs. Compressed by stroke force is 27.5 lbs. All spring forces are approximate.

BRONZE BUSHING oil impregnated, for good lubrication and long life.

CYLINDER ASSEMBLY is held together with high yield steel tie rods. This is recognized by industry to be the best way to provide pre-stressed construction for rugged service.

ROD SEAL is a self-adjusting modified U-cup. PISTON SEALS are self-adjusting modified U-cups. TUBE SEALS are O-rings located to prevent any possible

extrusion. PORTS are

1

/4" N.P.T.

MOUNTING may be accomplished by attaching the head, the cap, or side mounting by holes provided in the universal mount. Tie rod holes tapped thru for face mounting. Pivot or Clevis mount may be made by attaching brackets with cap screws provided (See Accessories Brochure).

PRESSURES of 250 psi pneumatic and up to 1500 psi hydraulic service.

CLA SERIES Dimensions

CLA SERIES cylinders are available in

3

/4" and 11/8" bores, double acting and spring return, universal and stud mounts, and in all strokes including fractions of inches. A full line of accessories is offered. (See Page CL-3)

CLA SERIES cylinders are rated for pneumatic service up to 150 psi. They are pre-lubed and do not require supplemental lubrication. Like all Sheffer pneumatic cylinders, this offers the unique advantage of continued operation when the lubricator is located too distant from the cylinder, when it has not been refilled, or becomes inoperative. Sheffer prelubed cylinders are also ideal for instrument air systems, food handling equipment or other applications where it is not practical or desirable to employ a lubricator or exhaust oil laden air into the environment.

CLA SERIES cylinders have been specified for years on automated conveyor systems, automated tool changing machinery, auto washing equipment, plastic forming presses, stamping machines, toggle locking mechanisms, and all types of clamping operations.

CLH SERIES Dimensions

CLH SERIES cylinders are available in a 1

1

/8” bore, doubleacting, spring return, universal mount and stud mount. All strokes are offered including fractions of an inch.

CLH SERIES cylinders are rated for pneumatic service up to 250 psi. Used as a pneumatic cylinder, this series is constructed to satisfy HEAVY DUTY applications. Slightly higher in cost than the CLA Series, the CLH is an economical answer to severe operating conditions. See separate Accessories Brochure.

CLH SERIES cylinders are rated for Hydraulic Service up to 1500 psi providing a low cost solution to small bore, hydraulic cylinder requirements.
