H-Block Series

Heavy-duty H-Block (HB) Series Guided Pneumatic Cylinder

This guided pneumatic slide cylinder accepts linear ball bearings with case hardened steel guide rods to provide high load capacity, low deflection, and low friction. Ideal for automated systems, manufacturing operations and other demanding load-bearing applications, this guided air cylinder can alternatively accept composite slide bearings with larger diameter chrome plated 1050 steel guide rods and bearing material. It’s the perfect heavy-duty pneumatic cylinder to handle impact, vibration, and weighty loads.

Nason always delivers on their promises. They guarantee delivery and price, and because of that, we can always be sure we’ll hit the mark for our customers.
They are a smaller company which makes communication simple and my job a lot easier. Their team has strong engineering capabilities and attention to detail on every project. I have the upmost admiration for these guys and the job they’re doing.

Bob Bewalda — Durable Controls Inc.

Nason cylinders are solutions. They are built to fit a design, not to make a design fit the cylinder. Nason will tailor the product to fit any configuration needed for your application. They’ll even take a competitive cylinder and redesign it better than the original. And not at a custom price.
The key thing with Nason is they design a high-quality cylinder that isn’t going to fail. They are good partners in the design process because they rely on me to give them as much information as I can. And their turnaround time is one of the best I’ve seen.

Mike Schapoehler — Airline Hydraulics

Nason produces high-quality cylinders at a very competitive price. Everyone is working with a tight budget and an even tighter timeframe. Every bit of savings is valuable.
Nason is also willing to produce small quantities of non-standard components to satisfy a customer’s needs and requirements. And I have never had an issue with defective quality or workmanship in a cylinder that we’ve purchased.

Dave Maurer — Air Engineering & Supply

Everything at Nason starts with a ‘yes’. They have a can-do attitude and a quicker response time than anybody else. They do the things that nobody else will do. If you’re in a jam and need something quickly, they are the best people to call.
Nason is so easy to do business with and that’s why we work with them.

Keith Elphick — Airline Hydraulics & Automation

Nason manufactures cylinders to each customer’s specifications. They ensure all of their customers get exactly what they need for each application. They are a small company, so you always get personalized attention.

Any application where I have a customer that wants to do something outside of the box and they need something right away I go to Nason.
