About cams & cam followers
Cams and cam followers translate rotary motion into linear motion or provide intermittent motion control. This category encompasses cam followers, track rollers, yoke rollers, and cam plates. Cam followers, often referred to as stud-type cam followers, integrate a stud for mounting, with common series including inch-dimensioned (e.g., CF, CYR) and metric-dimensioned (e.g., KR, NUKR) variants. They are characterized by bore diameter, overall length, stud diameter, and dynamic/static load ratings. Track rollers (e.g., LR, LFR series) and yoke rollers (e.g., NUTR, PWTR series) are bearing assemblies designed for linear guidance, typically mounted on an external shaft or stud. Key selection parameters for these include outer diameter, inner diameter, width, and load capacity. Cam plates, or cam profiles, are the active components that interact with followers to generate specific motion profiles. Materials commonly include hardened bearing steel (e.g., 100Cr6, SAE 52100) for rollers and studs, with options for corrosion-resistant stainless steel or surface treatments like black oxide or zinc plating. Seals, such as contact or non-contact types, are crucial for retaining lubrication and excluding contaminants, impacting operating temperature and service life.
How to choose
Selecting the appropriate cam or cam follower involves a sequential decision process. First, define the motion profile and load requirements: Does the application require intermittent indexing, linear guidance, or precise motion translation? This determines whether a cam plate with a specific profile or a linear track roller is needed. Second, consider mounting constraints: Is a stud-type (cam follower) or yoke-type (yoke roller) mounting preferred, or is an external shaft used (track roller)? This dictates the basic component type. Third, determine the required load capacity and operating speed, which influences the roller diameter, bearing type, and lubrication. Fourth, specify environmental conditions, such as temperature, moisture, or chemical exposure, to select appropriate materials (e.g., stainless steel), seals, and lubrication. Finally, verify dimensional compatibility with existing components and available space.
