What is a Hub with plain bore

A plain bore hub is a rolling system in which the wheel rotates directly on a bushing inserted into its central bore.

Thanks to its simple design, it is a reliable and cost-effective solution for a wide range of industrial applications, providing a good balance between load capacity, rolling performance and ease of maintenance.

Features and applications of the plain bore hub

Suitable for applications involving non-continuous movements and limited loads.

The relative sliding friction coefficient range is b= 0.003 - 0.005.

The plain bearing can be joined directly to the wheel bore. The axle set is made with a calibrated and machined tube to create a homogeneous and precision bearing coupling surface. Acting like a spacer, the tube is inserted into the bearing and tightened to the bracket using a screw and nut up to the predefined torque setting; the bearing slides freely on the tube. Axle sets can be supplied in the galvanised steel or stainless steel version. The centre of model P64 C/B is specifically dimensioned to obtain the variations for spline and key housing in the precision hole, in order to make this a drive wheel.
