The NTN NUKRT series is a cylindrical roller cam follower built with a crowned outer profile, made to carry high radial loads where the roller runs directly on a cam surface or raceway. It fits over a shaft through its inner bore, and its construction handles combined loads in machinery that demands a compact, durable bearing. MR Industrial Accessories LLC supplies this series to maintenance and purchasing teams in the United States and Latin America.

Reading the code helps you order the right roller. NUKRT is the family name for cam followers with cylindrical rollers and a crowned outer profile. The digits that follow give the outer diameter in millimeters, such as 30, 35, 40 or 47. The AS suffix marks a sealed execution with lifetime lubrication. In references like NUKRT 30/3AS or NUKRT 47X/3AS, the X can denote a dimensional or mounting variant, and the number after the slash (3) refers to the width or construction type. Always quote the complete part number.

Typical applications include actuating cams, linear guides, conveyors, machine tools, presses and automation equipment. Plants in the automotive, metalworking, food and packaging sectors rely on them when space is tight and the bearing must absorb radial loads and tilting moments. Because the sealed design keeps dust and moderate humidity out, maintenance intervals stay manageable.

Selection comes down to the radial and axial load the roller will see, the rotation speed and the working environment. The AS seal blocks contaminants and holds lubricant in place, so frequent relubrication is not required under normal conditions. Correct mounting matters as much as the part number: the roller and raceway must be aligned precisely, since excessive misalignment speeds up wear. Check that the shaft tolerance is right and that the rolling surface is ground and hardened.

NTN NUKRT cam followers can be interchanged with equivalent products from other manufacturers that use the same dimensional nomenclature. If you only have another brand's number or an unidentified part, send us the data and we will point you to the compatible equivalent. Interchangeability depends on outer diameter, width, bore diameter and seal type, so the series number alone is not enough.
