what is a Hub with roller bearings

A hub with roller bearings is a rolling system in which the wheel rotates by means of roller bearings fitted inside the hub.

Thanks to its low rolling resistance and high radial load capacity, this solution provides smoother movement than simpler rolling systems and is particularly suitable for industrial applications involving frequent handling, heavy loads and consistent long-term performance.

Suitable for applications involving non-continuous movements and heavier loads respect to wheels with hub with plain bore, as it guarantees low friction coefficients even in the presence of heavy loads.

The indicative sliding friction coefficient is b=0.0025.

The bearing with steel cylindrical rollers or stainless steel rollers, with plastic cage is assembled in the seat specifically obtained on the hub. The axle set is made with a calibrated and machined tube to create a homogeneous and precision roller bearing coupling surface.

Acting like a spacer, the tube is inserted into the roller bearing and tightened to the bracket using a screw and nut up to the predefined torque setting; the roller bearing slides freely on the tube. Axle sets can be supplied in the galvanised steel or stainless steel version.
