The INA NATR series cam follower with PP sealing is a heavy-walled cylindrical roller bearing designed to take high radial loads in guidance, cam and direct rolling movements on a track. Its solid outer ring allows the rolling track to be the roller itself, with or without an inner ring depending on the mounting. MR Accesorios Industriales supplies this line for automation, handling and machine tool equipment in Buenos Aires, Argentina.

The series designation is read in blocks: the letters NATR identify the INA family cam follower, the number that follows indicates the series size and the PP suffix indicates sealing on both sides. In the examples NATR5-PP, NATR6-PP, NATR8-PP, NATR10-PP, NATR12-PP, NATR15-PP, NATR17-PP and NATR20-PP this progression is visible: the higher the number, the larger the outer diameter and the greater the load capacity within the same family. When the mounting requires it, the variant with an inner ring is designated with additional letters before the sealing.

These rollers are used in cam guides, packaging machine carriages, handling and transfer systems, presses, bending machines and cutting equipment. In the Argentine market they appear in food, automotive and metalworking production lines, where direct rolling on a cam or a guide replaces a conventional bearing. They are also chosen in repetitive positioning applications, because the solid outer ring withstands track wear without deforming.

To select correctly, three things must be considered: the type of track on which the roller runs, the expected radial load and the sealing. The PP suffix protects against dust and moisture, so it is advisable in dirty environments or with frequent washdowns. Lubrication must be suitable for the working speed and temperature, and the mounting must guarantee alignment between the shaft and the track: misalignment accelerates outer ring wear. If the roller works on a cam, check the profile and contact before fixing the position.

Equivalences between brands are handled by dimensions and roller type, not by the commercial part number: a cam follower from another company with the same outer dimensions, width and sealing type can perform the function, but tolerances and load capacity must be compared. Replacing by similarity of nomenclature is not advisable. If you have the equipment's original part number or the housing dimension, send it via WhatsApp to MR Accesorios Industriales and we will help you identify the equivalent option within the INA line we supply.

In machines with several rollers on the same guide, check the clearance and the condition of the track before changing a single unit: a new roller on a worn track works poorly and does not last long. To request a quote, send us the complete part number, for example NATR12-PP, or the roller dimension and the mounting type. With that we verify the variant and reply promptly.
