Hub with ball bearings

This is the ideal solution for heavier loads and continuous movements.

The indicative sliding friction coefficient is b=0.0015.

The shielded ball bearings are placed inside the seats of the wheel hub. The tolerance of the seats ensures a proper coupling with the ball bearings. An internal spacer is also inserted between the ball bearings for a proper functioning of the ball bearings once the axle material has been fitted. The axle material can comprise the following components: Solution a): a machined axle bushing (to be inserted inside the ball bearings), two side spacers, a bolt and a nut. The axle material is tightened up by locking the nut on the bolt with a proper torque force. Solution b): two top hats (t-bushes), a bolt and a self locking nut. Each top hat is inserted inside each ball bearing bore. The side collar of the top hat works as a side spacer. The axle material is then tightened up by locking the nut on the bolt with a proper torque force. The axle components can be made of standard steel or stainless steel. The loose wheels and rollers can be ordered with bearing facilities only (please note that the internal spacer is not suppied along with the wheel without ball bearings).
