Description
NTN KR30X is a cam follower reference, within Bearings. Request a quote for KR30X via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The NTN KR series cam follower is a roller bearing with an integrated stud, designed to withstand radial loads and transmit motion directly on cams, guides and raceways. It is mounted with the stud fixed to the structure and the outer ring rotating on the contact surface. It is a compact and robust solution for lifting, conveying and automation mechanisms that require high load capacity and precise guidance.
The KR series designation is read as KR followed by a number indicating the outside diameter in millimeters, and the suffix X indicates a specific roller configuration. For example, KR30X, KR32X and KR35X correspond to rollers with outside diameters of 30, 32 and 35 mm respectively. The X suffix identifies a variant with particular sealing or profile shape characteristics, according to the manufacturer's coding. To select the correct roller, take into account the outside diameter, the width and the type of mounting your application requires.
These rollers are used in a wide variety of industrial applications in Argentina: conveying and lifting systems, machine tools, packaging equipment, robotics and automation, presses, and cam mechanisms in general. Industries such as food, automotive, metalworking and logistics use them for their ability to withstand combined loads and their wear resistance. MR Accesorios Industriales sells the NTN KR series to cover these needs with the quality of a leading manufacturer.
To select the right roller, consider the radial and axial load it must withstand, the rotation speed, the environmental conditions and the type of lubrication. Mounting must ensure correct alignment of the stud with the raceway to avoid eccentric loads that reduce service life. Check the sealing: rollers with lip seals are suitable for dusty or humid environments. Lubrication may be permanent or require periodic greasing depending on the design. Follow the manufacturer's recommendations for tightening and securing the stud.
Regarding equivalences, cam followers from different manufacturers can be interchanged if the main dimensions (outside diameter, width, stud diameter) and load capacities match. Brands such as SKF, INA, NSK or Timken offer similar products, but it is essential to verify the complete designation and tolerances. If you need to replace a roller from another brand, send us the part number and dimensions; at MR Accesorios Industriales we will indicate the compatible NTN alternative or another brand that fits your requirement.

At MR Accesorios Industriales we will quote it promptly and advise you so you choose the right option for your application.
