M Series

Round Line, Non-Repairable Cylinder Line

The M Series is a stainless steel body air cylinder line that is the perfect solution for tight design budgets. This cylinder is reliable and is designed and
built to maximize performance. It will exceed all of your light-duty cylinder application requirements. The M Series comes standard with a multitude of
value-added features such as stainless steel piston rods, roll-formed threads at both ends of the piston rod, and pre-lubed for non-lube added service.
Furthermore, Numatics has the design capabilities to customize a product for your specific application. These are just a sample of things that make the
M Series the Superior Interchangeable round body air cylinder line.

Piston Rod

The type 303 stainless steel piston rod is ground, polished, and roller burnished
for a mirror finish to ensure corrosion-free longevity.

Rod Thread

Roll-formed rod threads (at both ends) ensure a durable customer-end
connection as well as piston to rod connection.

Rod Bushing

Oil impregnated sintered bronze rod bushing provides excellent wear resistance
and anti-friction qualities for smooth operation and long life.

End Caps

The end caps are made from a high strength aluminum alloy.

Ports

Unrestricted (full-flow) ports in conjunction with rectangular slots on the
piston-mating surface (at both ends) enable the air to work on a larger piston
area for effortless breakaway (even at low pressures).

Tube

The type 304 stainless steel tube, drawn and polished to a micro-inch
finish on the I.D., enables low friction and longevity.

Crimp

The cylinder body is attached to the end caps using
innovative assembly equipment that ensures a consistent
and reliable double rolled-in crimp.

Piston

High strength aluminum alloy piston with blow-by flats
(double acting only) ensure proper and rapid seal inflation.
Piston rod connections are threaded (roll-formed threads),
sealed with Loctite Threadlocker®, torqued, and staked for a
solid, leak-proof connection.

Piston Seals

Low friction Buna N “U” cup piston seals (optional low and high temperature
seals) are wear compensating for millions of maintenance free cycles.

Magnet

Magnetic band position indication is optional in 9/16” – 3” bore sizes. The
magnet does not affect the overall length of the cylinder 3/4” – 3” bore sizes
(double acting only) but does add .250” to the overall length of the 9/16” bore
cylinders.

Rod Seal

The low friction Buna N “U” cup rod seal (optional low and high temperature
seals) is wear compensating to ensure longevity.

Pre-Lubricated

Pre-lubricated with our specially formulated oil based compound for extensive
maintenance free performance.
