4 inches swivel stem caster with brake and a loading capacity of 250 pounds (113 kg) and a maximum speed of 2.5mph. 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 W-4ESB casters.

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

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

4 inches casters are made for:

  • More or less long trips (30 to 50 feet)
  • Frequent use (20 to 50 times a day)
  • Carts weighting less than 400 pounds 
  • Narrow carts (between 16 and 24 in. wide)

W-4ESB has an electric conductivity version (ESD) : EW-4ESB

For more frequent use or longer trips, we recommend considering the W-6PSB 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 W-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. Flip the structure for a better access to the bottom pipes.
  4. Engage the wheel brake to lock the wheel.
  5. Tighten the nut located on the top of the stem for the rubber bushing to expend until it barely fits inside the pipe.
  6. Insert the wheel rod completely inside the pipe. Help yourself with a mallet if needed.
  7. Rotate the wheel clockwise until it grips firmly inside the pipe.
