Lightweight and mountable on the goBILDA® pattern, these yellow acrylic disc wheels are excellent for robots running on smooth surfaces!
Their rubber traction ring has a 70 shore A durometer which maximizes traction. Since it stretches over the wheel core with a deep cavity, you can be sure it won’t slip off during use!
When you know the RPM of this 4" wheel, you can calculate its linear speed in different units of measurement. Just use our handy formulas below!
Millimeters per Second:
Formula: RPM x 5.32
Example: 20 RPM x 5.32 = 106.4 mm/s
Meters per Second:
Formula: RPM / 188
Example: 20 RPM / 188 = 0.11 m/s
Kilometers per Hour:
Formula: RPM / 52
Example: 20 RPM / 52 = 0.38 km/h
Inches per Second:
Formula: RPM / 4.78
Example: 20 RPM / 4.78 = 4.2 ips
Feet per Second:
Formula: RPM / 57.3
Example: 20 RPM / 57.3 = 0.35 fps
Miles per Hour:
Formula: RPM / 84
Example: 20 RPM / 84 = 0.24 mph
