Air Presses & Arbors

Air presses and arbors support common shop, maintenance, and production work. Pneumatic presses use shop air for repetitive crimping, heat sealing, bending, forming, pressing, swaging, riveting, and burnishing operations, while motor shaft arbors and buffing spindles provide mounting points for abrasive or soft-centered buffing wheels on compatible shafts.

Helpful Buying Guide

Choose air presses and arbors for the job at hand

This category includes two distinct product types: air-powered presses for repeated press operations and arbors or spindles for mounting wheels on compatible motor or threaded shafts. Begin by identifying whether the application needs pressing force or a wheel-mounting connection, then compare the stated shaft, thread, wheel-width, capacity, and stroke details.

Use Cases

Match the tool to the task

Use pneumatic presses for repeated crimping, heat sealing, bending, forming, pressing, swaging, riveting, and burnishing. Use shaft arbors for abrasive-wheel mounting, and use the buffing spindle for soft-centered buffing wheels.

How to Choose

Start with the connection

For arbors, match the shaft type and diameter first: smooth 1/4, 3/8, 1/2, 5/8, or 3/4 inch shafts, or a 5/8-11 threaded shaft. Then select the required right-hand or left-hand thread direction.

Applications

Compare work setup requirements

Type D arbors have a wider shoulder that provides clearance and room to position workpieces around the wheel for buffing and polishing setups. Standard nut-lock arbors provide a wheel-mounting point on compatible smooth shafts.

Additional Info

Check stated capacities and details

Available press configurations include a 3/4-ton column press with a 4-inch bore and 2-inch stroke, plus a 1-3/4 ton arbor press with a 6-inch stroke. Some arbors state wheel-width capacity up to 1-1/4 or 2 inches.

Planning Guide

Plan the right fit before choosing

Press selection

Compare capacity, stroke, and press format

Pneumatic presses connect to an existing shop air supply and do not require electrical wiring, pumps, or motors. Choose the press configuration that aligns with the stated force and travel needed for the operation.

  • 3/4-ton column press with a 4-inch bore and 2-inch stroke
  • 1-3/4 ton pneumatic arbor press with a 6-inch stroke
  • Both formats are intended for repeated production and shop pressing operations
Arbor and spindle selection

Match shaft fit, threading, and wheel setup

Motor shaft arbors are designed around specific smooth shaft diameters, while the screw-lock arbor fits compatible 5/8-11 threaded shafts. Thread direction is an essential comparison point, with both right-hand and left-hand options represented.

  • Smooth-shaft fits include 1/4, 3/8, 1/2, 5/8, and 3/4 inch sizes
  • Right-hand and left-hand threaded arbor configurations are available
  • Socket set screws help secure compatible arbors to smooth shafts
  • The screw-lock arbor can use a hex adapter with longer screws for thicker abrasive wheels
Wheel-mounting considerations

Review wheel width and clearance needs

Where wheel width is stated, select an arbor that accommodates the intended wheel. For buffing and polishing work where workpiece positioning is important, Type D arbors provide a wider shoulder for added clearance.

  • One left-hand 1/2-inch shaft arbor accommodates abrasive wheel widths up to 1-1/4 inches
  • Selected 3/8-, 5/8-, and 3/4-inch shaft arbors accommodate wheels up to 2 inches wide
  • The 1/4-inch left-hand buffing spindle is a quick-change option for soft-centered buffing wheels and changes without washers or nuts
FAQ

Common questions before buying

What are pneumatic presses used for?

The listed pneumatic presses are designed for crimping, heat sealing, bending, forming, pressing, swaging, riveting, and burnishing operations.

What shaft sizes are represented by the arbors?

The summaries include arbors or a spindle for compatible 1/4, 3/8, 1/2, 5/8, and 3/4 inch smooth shafts, plus an arbor for 5/8-11 threaded shafts.

Why does thread direction matter on an arbor?

The available arbors include right-hand and left-hand threaded designs, so the arbor should match the required wheel-mounting application.

Which options provide added workpiece clearance?

The Type D arbors have a wider shoulder that provides clearance and room to position workpieces around the wheel for buffing and polishing setups.
