How to Choose a Hydraulic Shop Press: A Tonnage Guide

A hydraulic shop press handles the jobs that hand tools can't — pressing bearings and bushings in and out, straightening bent components, and forming metal. The most important buying decision is tonnage, and it's easy to get wrong in both directions. Here's how to match it to the work you actually do.

What Tonnage Actually Means

Tonnage is the maximum force the press can apply. Too little and the press can't complete the job, or you risk stalling it at its limit; far more than you need costs more and takes more floor space. The aim is a press comfortably above your typical heaviest job — not one you'd be running at its limit every time.

Comparing the Main Options

Air and Manual Operation

All three models support both air-powered and manual operation. Air operation is faster and less tiring for repeated pressing; manual operation means the press still works where no compressed air is available. Having both is practical for a workshop that may not always have the compressor running.

What You Can Use a Shop Press For

• Bearing and bushing installation and removal — controlled, even force instead of hammering.
• Straightening — correcting bent shafts, axles, and similar components.
• Bending and metal forming — shaping stock without a dedicated bender.
• General assembly — pressing together interference-fit components.

Safety and Setup

A press stores a lot of force, so treat it accordingly. Always use the press within its rated capacity, centre the load, use appropriate eye protection, and keep hands clear of the pressing area. The TMG-SP100 includes a protective grid guard as part of its design. Check that the floor and workspace can support the press's weight and that you have room to move around it.

Frequently Asked Questions

What size shop press do I need for a home garage? For occasional bearing work and light straightening, a 50 ton press is generally enough. If you expect to work on larger or heavier components, step up in tonnage so you're not running at the limit.

Do I need a compressor to use an air/manual shop press? No. These presses support both air and manual operation, so they work without compressed air; a compressor just makes repeated pressing faster.

Is a bigger press always better? Not necessarily. A higher-tonnage press costs more and takes more space. Pick the capacity that comfortably exceeds your typical heaviest job rather than the largest option available.

Final Word

Match tonnage to the heaviest work you do regularly, leave some headroom, and pick the operation mode that suits your workshop. Browse the full range in the Shop Presses collection, or get in touch with the TMG Industrial Australia team if you're unsure which size fits.Jacob
