  • 2.5 mph maximum speed

Electric conductivity (ESD) 3 inches swivel stem caster with pedal brake and a loading capacity of 150 pounds (68 kg) and a maximum speed of 2.5 mph. The stem-mount is made with a rubber bushing that expands into a 28 mm steel pipe to keep the wheel in place. See the Installation Steps tab for more information on how to install EW-3ESB casters.

Bolt size M12 (12 mm) Length 2 1/4" (57.15 mm)

Use the F-BUS component when this caster is used with the EP-96-ST pipe.

3 inches casters are made for:

  • Small trips (25 to 30 feet)
  • Infrequent use (10 to 20 times a day)
  • Carts weighting less than 400 pounds
  • Narrow carts (between 16 and 24 in. wide)

EW-3ESB has a non-electric conductivity version: W-3ESB

For more frequent use or longer trips, we recommend considering the EW-4ESB caster.

For carts that will go outside, roll on ramps or damaged floors, it's preferable to use 6 inches casters.

All casters are equipped with a precision ball bearing.

  1. Ensure you have the following parts:
    • 1x EW-3ESB
    • 1x 28mm pipe of your choice
    • 1x Wrench
  2. Ensure that the structure is levelled when supported by the pipes that will be wheeled. Otherwise, the height difference might cause the structure to sway.
  3. Engage the wheel brake to lock the wheel.
  4. Tighten the nut located on the top of the stem for the rubber bushing to expend until it barely fits inside the pipe.
  5. Insert the wheel rod completely inside the pipe. Help yourself with a mallet if needed.
  6. Rotate the wheel clockwise until it grips firmly inside the pipe.
