The NTN KRVT series is a cam follower that combines a cylindrical roller bearing with a built-in stud. Bolting the stud in place lets the outer ring turn and carry radial loads with high rigidity, making the unit suitable for cams, linear guides and raceways.

The part number breaks down into clear blocks. KRVT marks the stud-type cam follower family. The digits that follow give the outside diameter in millimeters, so you will see references such as KRVT16, KRVT19, KRVT22 and KRVT26. An X placed after the digits points to an execution variant, while the /3AS ending identifies an NTN sealing and lubrication configuration. That is why KRVT16/3AS and KRVT16X/3AS share the same diameter but are built differently inside. When you pick a part number, match outside diameter, width and sealing type to your application.

These rollers show up across many industries. Typical uses include valve actuation cams, guides on packaging machinery, chain conveyors, printing equipment, textile machines and automation systems. You will also find them in presses, punching machines and indexing devices that call for a bearing with high load capacity and rigidity. The integrated stud makes mounting simpler and lets these cam followers replace ball bearings where loads are more demanding.

Selection comes down to a few points: radial and axial load, rotation speed and the surrounding environment. The /3AS seal keeps contaminants out and lubricant in, which suits dusty or damp locations. During installation, tighten the stud with a nut or screw and verify alignment with the raceway, since poor alignment speeds up wear. Depending on the variant, lubrication may be permanent or relubricable. When the roller runs against a cam, the contact surface should be ground and have the proper hardness.

Cam followers from different manufacturers carry similar designations, but letters and suffixes change from brand to brand. If you have a part number from another maker, send it over and we can point you to the NTN equivalent. Interchangeability hinges on the main dimensions (outside diameter, width, stud diameter) plus the sealing type, and not every variant swaps with another, so checking the full designation matters.
