Abstract

A guide carriage is configured for use with an guide rail. The guide carriage has at least one row of rolling bodies received in a circulatory channel. The circulatory channel has a load-bearing section and a return channel connected together at their ends by a deflection channel. The load-bearing section is delimited by a carriage raceway on the guide carriage and a rail raceway on the guide rail. At least one sealing lip is arranged in sealing engagement with the guide rail when the guide carriage is mounted on the guide rail. At least one separate rolling-body guide part, composed in one piece of an elastomer, has two deflection sections, between which at least one guide section, extending longitudinally, is arranged. An associated sealing lip is arranged on the guide section. At least one radially inner deflection surface of a deflection channel is arranged on each deflection section.
