The SKF cam follower of the NATR PPXA series is a cylindrical roller bearing with an integrated stud, designed to withstand high radial loads in cam and linear guidance movements. Its robust construction and side sealing make it suitable for demanding applications where lubrication must be retained and contamination kept out. It mounts directly onto the shaft and is secured with a nut or retainer, which simplifies assembly and maintenance in industrial equipment.
The NATR designation identifies a support roller with an inner stud and cylindrical rollers, for general use in cams and raceways. The number that follows, as in NATR 20 PPXA, indicates the shaft diameter in millimeters. The PPXA suffixes indicate a special seal: double contact lip with lifetime grease, designed for dusty or humid environments. Knowing this nomenclature allows you to order the exact replacement without ambiguity.
These rollers are used in machine tool cams, chain and belt guides, lifting systems, presses, packaging and conveying equipment. In Argentine industry they appear in automotive production lines, food plants and plastics factories, where precision and wear resistance are critical. Their ability to withstand combined loads and moderate speeds makes them versatile in reciprocating motion mechanisms.
To select the correct roller, verify the shaft diameter and the radial load it must withstand. The PPXA seal comes pre-lubricated and requires no additional maintenance, but it is important that the raceway is ground and has the appropriate hardness. During mounting, ensure precise alignment to avoid parasitic axial loads. Axial fixing is achieved with the elements provided by the manufacturer, and the internal clearance is not adjustable.
SKF rollers of the NATR series are interchangeable with those of other brands that follow the same dimensional and load standard. When looking for equivalents, compare not only the shaft diameter but also the overall width, the outer diameter and the type of seal. MR Accesorios Industriales carries this official brand and can advise you on the best option for your application, guaranteeing compatibility and performance.
