A cam follower from the NTN KR series combines a roller bearing with a threaded stud, letting you mount it straight onto a machine frame and run it along a cam profile or a linear guide. The stud carries the radial load with high rigidity, so the unit works well in cam mechanisms, conveyors, machine tools and automation equipment. MR Industrial Accessories supplies the KR series to customers throughout the United States and in several Latin American countries, and can help you pin down the correct part number.

Reading a KR code is straightforward once you know the pattern. The letters KR mean a cam follower with a threaded stud. The number that follows, as in KR16FX, KR19FX, KR22FX or KR26FX, relates to the roller's outer diameter. The FX suffix marks a construction variant inside the series, typically tied to the seal type and the end shape. Before you order, have the outer diameter, the stud diameter and the mounting thread on hand.

Typical duties include cam tracks on automatic machines, conveyor guides, cutting and bending systems, and packaging or bottling lines. The roller either transfers cam motion or acts as a rolling support in a guide. Mounting is simple thanks to the threaded stud, and in many designs lubrication can be renewed through the axial passage.

Selection comes down to the radial and axial load, the rotation speed and the working environment. The FX seal keeps out dust and moisture, which makes it a sensible choice where particles are present. The support surface must be flat and perpendicular to the stud, and alignment needs care so lateral loads do not build up. Pick a lubricant that suits the speed and the seal type; relubrication through the stud passage is often possible.

Cam followers can be swapped between manufacturers when the key dimensions line up: outer diameter, stud diameter and length, thread and seal type. When comparing brands, check that load capacity and seal design are equivalent. If you only have another brand's part number or an unidentified part, send it over and we will identify the matching NTN option or the one that suits your application best.
