Frequently Asked Questions

What cylinder types can I find at G&G Hydraulics?

Browse our inventory and you’ll discover single-acting, double-acting, and spring-return options. We don’t skimp on materials–only tough steel and aluminum cylinders make it to our shelves. Need specific capacities? Various stroke lengths? Different mounting styles? We’ve got ‘em all. Just filter by your specs on our site to narrow down choices fast.

Why pick aluminum cylinders instead of steel?

Weight savings is the big one–up to 65% lighter than steel models. This makes positioning way easier, especially in tight spots. Don’t worry about durability, though: our hydraulic cylinders for sale can handle corrosive environments. Many contractors choose aluminum for mobile applications or when frequent repositioning is needed. 

Can your cylinders handle serious industrial workloads?

Our cylinders are built like tanks, and everything we stock is designed to withstand the demands of an industrial worksite. You’ll find cylinders that keep performing through thousands of cycles. No weak components here, just serious industrial-grade hydraulics.

How do I choose the right industrial hydraulic cylinder to meet my needs?

When looking for hydraulic cylinders for sale, it’s important to match cylinder tonnage to your load plus a hefty safety margin (20% should be good). Consider duty cycle: occasional use versus continuous operation requires different designs. Check your spatial constraints and required stroke length. Think about your environment: high-temperature applications need special seals. Don’t forget the mounting style: clevis, flange, or side-mount options affect installations. You can always contact us with your specifics! 

What maintenance is required for hydraulic cylinders?

Inspect seals monthly for leaks – tiny weeps can eventually become floods! Keep rod surfaces clean; even small scratches can ruin seals. Check the mounting points for looseness (our hydraulic cylinders for sale are guaranteed not to have this problem!). Store cylinders with rods fully retracted when possible. Replace hydraulic fluid annually or after 1,000 hours of operation. Most importantly: document pressure ratings and never exceed them, even “just this once.”

What are the differences between single-acting and double-acting cylinders?

Single-acting cylinders use hydraulic pressure to extend but rely on gravity or springs to retract – perfect for simple lifting jobs. Double-acting models apply hydraulic force in both directions, giving precise control during both extension and retraction. Double-acting cylinders cost more but offer better control for positioning tasks. For pure lifting power, single-acting often does the trick.
