The McGill CYR S series cam follower is a roller bearing designed to follow the profile of a cam or a linear guide. Its inch configuration and robust construction make it suitable for transmitting motion precisely in mechanisms where the load is radial and the speed is moderate. It is used in automation, conveying and production machinery. MR Accesorios Industriales supplies this line as a brand for the Argentine market.

The CYR S designation is read as follows: CYR identifies the inch cam follower family; the number that follows, expressed in fractions of an inch, indicates the outside diameter of the roller, as in CYR 1 1/2 S or CYR 1 1/4 S. The final letter S indicates a construction variant within the series, usually linked to the type of sealing or the shape of the stud. The examples CYR 1 S, CYR 1 1/8 S and CYR 1 3/4 S show how the size changes without altering the logic of the part number.

In Argentine industry, these followers appear in machine tool cams, indexing systems, chain conveyors, presses and packaging equipment. They are also found in rolling guides of textile, food and plastics machinery, where the cam rotates at moderate speed and the load is mainly radial. Their inch format is common in imported or US-designed equipment that already uses this series.

To select a CYR S properly, take into account the outside diameter your cam needs, the roller width and the type of stud. The S variant defines the sealing: verify that it is compatible with the environment (dust, chips, humidity). Installation requires careful shaft alignment and adequate lubrication; in high-load applications, check the internal clearance and the stud fastening. A misaligned cam shortens the life of the follower.

Inch cam followers are interchangeable between manufacturers if the outside diameter, width, stud diameter and length, and type of sealing match. It is not enough for the designation to be similar: the dimensions and load capacity must be compared. If your equipment has a McGill part number, the safest option is to request that same part number or its verified dimensional equivalent. MR Accesorios Industriales can help you with that comparison.
