The CF-2-SB is an inch-series stud-type track roller bearing—often referred to as a cam follower—featuring an outer diameter of 50.8 mm (2 inches). Designed with a full-complement needle roller configuration, it serves as a critical component in high-load, precision motion mechanisms.
Key Features
High Load Capacity: The thick-walled outer ring, combined with a full-complement needle roller design, maximizes the number of rolling elements. With a dynamic radial load rating of approximately 36.1 kN, it offers excellent impact resistance, making it ideal for low-speed, high-load, or oscillating applications.
Easy Installation: The stud-type track roller bearing features an integrated stud and roller design, replacing the traditional inner ring. It features a standard 7/8-14 thread for direct mounting, and a hexagonal socket in the stud end facilitates assembly and secure tightening, eliminating the need for a separate bearing housing.
Effective Sealing and Maintenance: Equipped with a standard "Lubri-Disc" seal, it prevents dust ingress and grease leakage. An internal lubrication channel within the stud allows for the replenishment of grease, thereby extending the bearing's service life.
Structural Stability: The integral raceway of the stud-type track roller bearing is hardened, and the outer ring is axially guided by needle rollers; it can accommodate certain bidirectional axial loads and offers high tolerance for misalignment.
Typical Applications
- Conveyor systems, rail-guided mechanisms, and positioning devices in automated production lines.
- Heavy-duty oscillating or linear-tracking components, such as those found in machine tool tool-changers and industrial fixtures.
- Cam-driven systems and pressure-roller assemblies in packaging and printing machinery.
- Support rollers for heavy-duty door mechanisms, lifting platforms, and auxiliary metallurgical equipment.
With its compact design, high rigidity, and ease of installation, the CF-2-SB excels in low-speed, high-load environments—particularly in mechanisms that require precise rolling motion along a track or rail.
