Question by: Neil H on Mar 2, 2026, 10:55 AM

got a setup that can’t use any fancy adjusters or ratcheting, is this SM Series unit the plain-jane style?

Answer by: Customer Support on Mar 3, 2026, 5:28 PM

Built as a straightforward SM Series cylinder, it does not have an adjustable end and it does not include a ratcheting mechanism, so it fits systems that need consistent operation without those add-ons.

What size is the bore on this cylinder? Just want to make sure it'll fit my setup.

It's got a 1-1/8 inch bore, so you'll want to double-check that lines up with what you're replacing.

Part number SM-1-1/8X2, that's the one without the check valve, right? Just want to make sure before I order a handful of these for our line.

Correct, no check valve is included on this unit. The SM Series with that part number is built for systems where you need clean, straightforward pneumatic or hydraulic actuation without any additional valve components in the circuit. If your system already handles flow control upstream, this fits that setup well.
