Special manually operated instruments with an electronic digital readout:
Model 4165L

The model 4165L set is intended to be used when selecting the outer and inner races of bearings in order to obtain the needed radial clearance in the assembled bearing.

The set consists of an electronic unit and any number of twin measuring devices (for races of different standard sizes) that are in turn connected to the electronic unit.

A distinguished feature of the set is as follows: when the set measures the outer and inner races of a bearing, on the electronic unit’s display one reads the the value of the radial clearance depending on the combination of the diameters of the races and rollers.The latter are sorted out into size groups with the aid of model 4155L Instrument of the ROBOCON company.


The Instrument has been certified by the State Standard Committee of the Russian Federation.
