Static-Control Rubber Wheels
 |  |
These wheels dissipate static to protect sensitive electronic equipment from electrostatic discharge. The soft rubber wheels are shock absorbing and provide good traction on rough surfaces. Sleeve bearings prevent wear to the wheel bore but don't roll as easily as other bearings. Wheels meet FF-C-77 and FF-C-86 which requires an average electrical resistance of less than 250,000 ohms.
