## Description

Rolling roller bearing units of the R88, R88U and R88Sh models are designed for use in rolling guideways. They allow smooth movement of the moving parts of a machine over a long stroke (practically unlimited) at speeds from 1 to 10 m/min. with low friction losses (reduced friction coefficients 0.002.....0.004) and take considerable loads acting perpendicular to the plane of movement of the moving part of the machine. The roller bearing units are intended for use in machines of normal and increased accuracy.Climatic version per GOST 15150-69-UHL4. Application: 6M610F11 , 2204VMF4, 3M642, 3B641 and others...
