Product Description Cam Follower Bearings (Yoke Rollers with Needle Roller Interiors)Overview:A cam follower bearing, also known as a yoke roller, is a highly specialized and robust bearing designed to follow tracks, cams, or guide rails. Its defining feature is a thick-walled, outer ring that acts as the rolling contact surface, mounted onto a integral stud (pin) which serves as the shaft. The internal rolling elements are needle rollers, which provide an exceptionally high load-carrying capacity within a compact cross-section. This design makes them ideal for applications with high shock loads, limited space, and demanding motion profiles.Key Design Features & Advantages:Exceptional Load Capacity: The internal needle roller construction allows these bearings to support very high radial loads-significantly higher than similarly sized ball bearing cam followers-due to the large contact area.Robustness & Durability: The thick outer ring is through-hardened and precision-ground to withstand high impact loads, shock loads, and resist brinelling. The integral stud is also hardened for strength.Compact Design: The needle roller design achieves maximum load capacity with a minimal cross-sectional height, optimizing space efficiency in machinery.Lubrication & Sealing: Most models feature built-in lubrication holes (through the stud or side holes) and are equipped with high-performance seals to protect the needle rollers and raceway from contaminants like dirt, dust, and moisture, ensuring long service life.Stud Integrity: The stud is designed with a tight tolerance fit between the thread and the body diameter to ensure precise alignment and prevent misalignment during operation.Common Types & Configurations:Standard Crowned (Type CR/CF):Description: The outer ring has a slightly crowned (convex) profile. This design helps compensate for minor misalignments and prevents stress concentration at the edges of the ring, promoting even wear and a longer lifespan.Example Models: CF 8 (Stud Thread M8x1.25), CR 12180 (12x18x12mm)Full Complement (Type CF…-LL):Description: Utilizes a maximum number of needle rollers without a cage, offering the highest possible radial load rating. Best suited for slow oscillating or rotary motions.Example Models: CF 12 LLStudded Track Rollers (Type NATR/NUKR):Description: Similar to cam followers but often feature two retaining lips to secure the needle roller and cage assembly axially. The outer ring has a flat or slightly crowned profile.Example Models: NATR 12 PPX (M12x1.5 thread)Standard Sizing & Model Numbers:Sizing is typically denoted by the stud thread size and the outer ring dimensions.Stud Thread: Common metric threads include M6, M8, M10, M12, M14, M16, M20.Outer Ring Dimensions: Given as Outside Diameter (D) x Width (C). Common sizes range from small (e.g., 16x12mm) to very large (e.g., 100x54mm).Example: A model CF 24 has a stud thread of M24x1.5.Primary Applications and Industries:Cam followers are essential components in machinery requiring precise tracking and high load support.Material Handling: Conveyor systems, cam-driven indexing tables, transfer lines, and packaging machinery.Automation & Robotics: Linear guide systems, pick-and-place units, and assembly automation.Printing Industry: Guides and supports in large printing presses.Automotive Manufacturing: Welding fixtures, lifting platforms, and production line conveyors.Textile Machinery: Guides for yarns and fabrics under tension.
