CF-SFU-R SERIES

THK Cam Follower Model CF, CF-SFU, CF-SFU-R SERIES represents a specialized category of linear motion components engineered for applications involving high-load capacity, shock resistance, and precise guidance along cam profiles or guide rails. These cam followers feature a stud-type design with a thick outer ring and needle roller construction, optimized to withstand heavy radial loads, moment loads, and intermittent impact forces in demanding industrial environments. The series includes variations such as the standard CF type, the CF-SFU with a screw plug for easy lubrication, and the CF-SFU-R with a slotted hole in the stud for simplified adjustment and alignment during installation.

Technical features of the CF SERIES highlight robust construction and enhanced durability. The outer ring is manufactured from high-carbon chromium bearing steel (SUJ2) and subjected to precision grinding and heat treatment, resulting in a hardened surface that resists wear and extends service life. The needle roller assembly ensures smooth rotation under high-speed conditions, while sealed versions incorporate contact or non-contact seals to prevent contamination from dust, debris, or moisture. The CF-SFU model includes a screw plug on the outer ring, allowing direct grease replenishment without disassembly, which minimizes maintenance downtime. For the CF-SFU-R type, the slotted stud hole enables fine positional adjustments along the mounting surface, accommodating misalignments and simplifying assembly in constrained spaces.

Performance advantages of these cam followers include exceptional load-bearing capacity, with dynamic load ratings often exceeding conventional ball bushings, making them suitable for heavy-duty applications. Their low friction coefficient and high rigidity contribute to precise motion control, reducing vibration and noise during operation. The sealed designs enhance reliability in harsh environments, such as those with particulate contamination or exposure to coolants, while the lubrication options ensure consistent performance over extended periods. These attributes lead to reduced maintenance intervals, lower total cost of ownership, and improved machine uptime.

Typical applications span multiple sectors, including industrial machinery where CF SERIES components are employed in automated assembly lines, packaging equipment, and material handling systems for guiding moving parts along cam tracks. In automotive manufacturing, they serve in welding robots, transfer lines, and press feeds, handling high dynamic loads and repetitive motions with precision. Precision equipment applications include semiconductor manufacturing devices, printing machinery, and textile looms, where smooth, accurate linear motion is critical. The versatility of the CF, CF-SFU, and CF-SFU-R SERIES makes them indispensable in scenarios requiring reliability under extreme conditions, ensuring efficient and long-lasting performance across diverse industries.
