Rubber Wheels
Solid rubber wheels offer a durable ride with no possibility of tread separation. Sleeve bearings in these wheels prevent wear to the wheel bore but don't roll as easily as other bearings.
Soft wheels are shock absorbing and provide good traction on rough surfaces. Hard wheels are impact resistant and roll easily on smooth surfaces, but can be noisy and damaging to floors.

Oil-Resistant Rubber Wheels
These neoprene rubber wheels won't degrade when they come into contact with oil, mild acids, and solvents. They are just as shock absorbing as other rubber wheels but are more resilient. Use them on smooth or rough surfaces.
Sleeve bearings prevent wear to the wheel bore but don't roll as easily as other bearings. Ball bearings are the easiest to roll.
Shielded bearings protect from dust and debris.

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.
