The NTN KR FLLH series is a cam follower: a roller bearing on a threaded stud that mounts straight onto a cam, guide or rail. It handles radial loads in reciprocating motion, and its sealing suits dusty or chip-filled areas where lubrication must stay in place. Typical uses include cam drives, conveyors, machine tools and automated equipment. MR Industrial Accessories quotes these by exact part number or size.
Read the code in sections. KR marks the threaded-stud cam follower; the digits after it give the outside diameter in millimeters, so KR22FLLH/3AS is 22 mm and KR26FLLH/3AS is 26 mm. FLLH covers the seal and cage arrangement, and /3AS points to the surface treatment and factory fill. Those suffixes are what separate an open unit from a sealed or coated one, so order by the complete number.
Cam followers of this type show up in actuating cams, linear guides, chain conveyors, packaging machinery, presses and automation, as well as in metalworking, food and automotive plants that need a compact bearing for radial loads and tilting moments. Since it is a precision part, match the sealing variant to the site: where abrasive dust or chips are present, the FLLH seal helps hold lubricant and keep contaminants out.
Selection comes down to outside diameter, stud diameter and pitch, and overall width. Confirm the running surface is hardened and ground and that the thread fits the housing. When mounting, line the follower up with the track to prevent side loads, tighten to the torque given for that size, and apply initial lubrication. For high speeds or combined loads, check internal clearance and cage type.
NTN cam followers can interchange with other European and Asian brands using similar basic nomenclature (KR, KRV, NUKR and so on), but sealing and treatment suffixes differ. When replacing a part, the diameter alone is not enough; compare the full part number or the critical dimensions. If you have another brand's number, MR Industrial Accessories can identify the equivalent and quote the option that fits your application.
To get a quote, send the exact part number by WhatsApp (for example, KR22FLLH/3AS or KR26FLLH/3AS) or give us the dimensions of the part you are replacing. MR Industrial Accessories replies promptly and helps you choose so the cam follower performs as your equipment requires.

Frequently asked questions
- What does the FLLH suffix mean on an NTN cam follower?
- FLLH denotes a specific seal and cage configuration. In practice it means the cam follower has seals that keep lubricant in and contaminants out, along with a particular cage design. Always check the full part number to avoid mixing up variants.
- How do I choose between a sealed and an open cam follower?
- If the environment has dust, chips or moisture, go with a sealed cam follower such as the KR FLLH series. In clean applications with controlled lubrication, an open cam follower may be sufficient. The decision depends on contamination and how often you relubricate.
- Can I replace a cam follower from another brand with an NTN one?
- Yes, provided the critical dimensions match: outside diameter, stud diameter and pitch, and width. The KR nomenclature is common to several manufacturers, but the suffixes vary. Send us the original part number and we will tell you the NTN equivalent.
