3'' Stem ESD Swivel Caster With Brake
- Electric conductivity (ESD) caster
- 3 inches (74 mm) diameter wheel
- 150 pounds (68 kg) loading capacity
- 2.5M/h 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 2.5M/h. 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)
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.

- Ensure you have the following parts:
- 1x EW-3ESB
- 1x 28mm pipe of your choice
- 1x Wrench
- 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.
- Engage the wheel brake to lock the wheel.
- Tighten the nut located on the top of the stem for the rubber bushing to expend until it barely fits inside the pipe.
- Insert the wheel rod completely inside the pipe. Help yourself with a mallet if needed.
- Rotate the wheel clockwise until it grips firmly inside the pipe.
