Product Description Cam Follower Bearing: English IntroductionOverviewA Cam Follower Bearing (also known as a Track Roller or Yoke Roller) is a specialized type of roller bearing designed to follow tracks, cams, or guide rails in machinery. It consists of a thick-walled outer ring, a precision needle roller or cylindrical roller set, and an integral stud (pin) that serves as the mounting shaft. These bearings are engineered to withstand high radial loads, shock loads, and oscillating or linear motions, making them ideal for applications where space constraints and heavy-duty performance are critical. Key FeaturesHigh Load Capacity:The internal needle/roller design provides a large contact area, enabling exceptional radial load capacity despite a compact cross-section.Durability:Hardened and ground outer ring (typically case-hardened steel or stainless steel) reswear, brinelling, and corrosion.Sealed variants protect against contaminants like dust, dirt, and moisture.Versatile Configurations:Crowned Outer Ring: Compensates for misalignment and reduces edge stress (e.g., CR/CF series).Flat Outer Ring: Suited for precise linear guidance (e.g., NATR series).Stud Options: Male threads (e.g., M8, M10, M12) or female threads for easy mounting and adjustment.Lubrication:Pre-lubricated with high-temperature grease for lifelong operation or designed for relubrication via grease nipples.

ApplicationsCam followers are widely used in:Material Handling: Conveyor systems, packaging machinery.Automation: Linear guides, robotic arms, pick-and-place units.Automotive: Welding fixtures, assembly lines.Printing Presses: Paper guidance systems.Textile Machinery: Yarn tension control systems. Why Choose Cam Followers?Space Efficiency: Ideal for compact designs where radial space is limited.Shock Resistance: Robust construction handles high-impact loads.Low Maintenance: Sealed and pre-lubricated options reduce downtime.Precision: Ground surfaces ensure smooth motion and accurate tracking. Material OptionsOuter Ring: Case-hardened chromium steel (SUJ2/52100), stainless steel (440C).Stud: Hardened steel or stainless steel.Rollers: Precision-ground needle rollers or cylindrical rollers.Seals: Nitrile rubber (NBR) or fluoroelastomer (FKM) for high-temperature resistance.
