Lynair Mill Type Cylinders

Lynair's Mill-Type cylinder series include: Series MTA Mill-Type Air, Series MTH , MHH, and M3H Mill-Type Hydraulic, Series TMA Torpedo Mill-Type Air, and TMH Torpedo Mill-Type Hydraulic.
Air and MTH Hydraulic Cylinders
Typical Construction Features:

PRESSURE RATING

Series “MTA” Mill Type air cylinders are rated for 250 P.S.I. service. “MTH” models are rated for hydraulic service pressures of 1000 P.S.I. for 2 thru 10 bores, and 500 P.S.I. for 12 thru 20 bores.

ADJUSTABLE CUSHION OPTION

Cushions are optional at either one or both ends of the cylinder. When provided, close fit- ting surfaces of mating components trap oper- ating fluid to decelerate the piston before it reaches the “end of stroke” position. Rod end cushions are self-compensating to adjust for minor alignment variations. Flush fitting Cushion Screw permits adjustment in decel- eration rate while interchangeable Ball Check aids start up upon reversal of travel direction.

CYLINDER TUBE WITH \ WELDED FLANGE RINGS

Heavy wall steel tubing is honed to 15 micro inch finish after welded flange rings are attached. Surface of bore is hard chrome plated to resist wear and promote optimum seal life.

O-RING TUBE END SEALS

Seal located on pilot diameter between tube and head provides leak-free seal at maximum operating pressure levels.

CYLINDER PORTS

N.P.T.F. Ports are unobstructed permitting use of maximum flow area.

PISTON ROD

Precision ground, polished, and hard chrome plated piston rods made from high yield strength steel are offered with the choice of standard male or female thread options. Male rod threads thru 11/2 diameter are rolled for maximum strength and uniformity. Four wrench flats are provided to aid in making the rod end connection. The rod surface is reduced in size in area of flats to eliminate contact with seals at assembly.

ROD BEARING / REMOVABLE RETAINERS

Precision machined bronze bearing supports and centers rod to maintain concentricity with bore while providing support for V-ring seal set. Two-piece bearing with inner section that provides rod support during seal replacement is used when design permits. Retainer construction allows bearing removal without disassembly of head retaining bolts.

ROD SEAL

Pressure energized multiple lip packing set consists of four fabric reinforced Buna-N V- ring seals plus male and female adapter rings. Seal set is self compensating to adjust for nor- mal wear while providing long lasting, trouble free service.

ROD WIPER

Double Lip Wiper cleans rod surface of cont- aminants and prevents entry of harmful par- ticles into sensitive bearing and seal areas. Integral cup form on inboard side of wiper serves as secondary seal to insure leak-free performance.

INTERIOR MATERIALS / EXTERNAL FINISH

Front Head, Rear Head, and Flange Rings are accurately machined from carbon steel plate. Cylinder Tubes, Bearing Retainers, and mountings are constructed of steel for maxi- mum strength and durability. Cylinders have enamel finish on exterior with mounting and machined surfaces protected by anti-rust film lubricant at time of ship- ment.

PISTON/SECURELY LOCKED

One piece high tensile cast iron piston with wide surface area contacting cylinder bore stabilizes rod and reduces bearing loads. The piston is pilot fitted onto rod and secured by self-locking nut when sizes permit.

PISTON SEALS

Low friction, self compensating cup type seals provide long, trouble free service. Cylinder sizes thru 6” Bore have seals of lubricated (sil- icone) urethane material. Other bore sizes are equipped with seals of Buna-N. Piston seals are elastic and snap into piston grooves for easy installation.

RUGGED RETAINING BOLTS

High tensile alloy bolts with self-locking hex nuts are used to secure the cylinder assembly.

SPECIAL CYLINDERS

Variations in construction involving the use of non-standard dimensions, materials, or cylin- der feature modifications are available upon request. Full engineering and manufacturing facilities are available to produce the exact cylinder to meet design requirements.

1000 psi Mill Type Hydraulic Cylinder

PRESSURE RATING

Series “MTA” Mill Type air cylinders are rated for 250 P.S.I. service. “MTH” models are rated for hydraulic service pressures of 1000 P.S.I. for 2 thru 10 bores, and 500 P.S.I. for 12 thru 20 bores.
