ABSTRACT:
An industrial wheel for trolleys, carts, pulleys. And the like with a self lubricated bearing of fuoroplastic, or the like, that slants at an angle from the center of the wheel out to the rim, so as to have a larger surface area, with consequent lower force or friction. The slanted bearing also locates the wheel in the center, eliminating the need for retaining devices along sides of the wheel.
