The NTN NUKRT series cam follower is a cylindrical roller bearing with a crowned outer profile, designed to withstand high radial loads in cam and linear guidance applications. It mounts on a shaft through its inner bore and rolls directly on the cam surface or raceway. Its robust construction and ability to withstand combined loads make it suitable for demanding machinery. MR Accesorios Industriales sells this series with NTN quality.

The NUKRT series designation is read in parts: NUKRT identifies the cam follower family with cylindrical rollers and a crowned outer profile; the number that follows indicates the outer diameter in millimeters (for example, 30, 35, 40 or 47). The AS suffix indicates a sealed execution with lifetime lubrication. In examples such as NUKRT 30/3AS or NUKRT 47X/3AS, the letter X may indicate a dimensional or mounting variant, while the number after the slash (3) refers to the width or construction type. Know the complete part number for an accurate selection.

These rollers are used in actuating cams, linear guides, conveyors, machine tools, presses and automation equipment. In Argentina, they are common in the automotive, metalworking, food and packaging industries, where a compact bearing that withstands radial loads and tilting moments is required. Their sealed design makes them suitable for environments with dust or moderate humidity, reducing maintenance.

To select the correct roller, take into account the radial and axial load it must withstand, the rotation speed and the environmental conditions. The AS seal protects against contaminants and retains lubricant, so it does not require frequent relubrication. Mounting must ensure precise alignment between the roller and the raceway; excessive misalignment accelerates wear. Verify that the shaft has the appropriate tolerance and that the rolling surface is ground and hardened.

NTN NUKRT series cam followers can be interchanged with equivalent products from other brands that follow the same dimensional nomenclature. If you have another brand's part number or an unidentified part, send us the data and we'll indicate the compatible equivalent. Interchangeability depends on the outer diameter, width, bore diameter and seal type; do not rely on the series number alone.
