Precision measurement, wafer inspection, positioning machining, assembly, laser cutting, and more. 🧬 Wire-Track Bearing Components (LEL/LED… series) These are Franke’s most core and fundamental products. They are not complete “finished bearings” but rather raceway assemblies made from spring steel wire—think of them as “bearing components.” LEL (High-Precision Type): Designed for demanding motion performance and accuracy, with installation clearances ranging from just 5.9 mm to 20.9 mm. LED (Heavy-Duty Type): An enhanced version of the LEL series, offering higher load capacity, larger internal ball sizes, and a sturdier overall structure. LER (Economy Type): Suitable for moderate speeds and accuracy. Compact cross-section and excellent cost-effectiveness. LEG (Innovative Type): Uses dual raceways to replicate the four-point contact functionality of traditional four-point-contact bearings, resulting in a more compact and simpler design. LDD (High-Speed Precision Type): Specifically engineered for high-speed, high-precision rotary motion. LDL (Double-Row Ball Type): Similar in design to the LDD, also optimized for high-speed, high-precision applications. LDV / LDH (Special-Structure Types): LDV often incorporates external gears for direct meshing with power drives, while LDH is typically tailored to meet specific geometric or load requirements. LEW (Crossed-Roller Type): Utilizes crossed cylindrical rollers, making it insensitive to shock and vibration while delivering high rigidity and load capacity. 🧩 Bearing Assemblies (LVC/LVD/LVE… series) You can think of these “assemblies” as “pre-packaged finished products.” They consist of the basic component encased in an aluminum or POM plastic housing, often with integrated gears, so they’re ready to install and use right out of the box. LVC (Steel High-Speed Type): Steel housing with a double-row angular-contact ball bearing design, enabling extremely high rotational speeds and outstanding dynamic performance. LVD (External-Gear Steel Type): Steel housing with external gears for direct drive, ideal for medium-speed, medium-accuracy applications. LVE (External-Gear Aluminum Type): Aluminum housing with toothed belt gears, featuring a lightweight design suited for medium-speed scenarios. LVG (High-Load Aluminum Type): Aluminum housing with double-row angular-contact roller bearings, optimized for maximum load capacity and rigidity. LVK (Plastic Economy Type): POM plastic housing, moderate speed, highly cost-effective, environmentally friendly, and practical. LVL (External-Gear Plastic Type): POM plastic housing with external gears, moderate speed, retaining all the cost-efficiency and environmental advantages of plastic housings. LVM (Gear Plastic Type): POM plastic housing with transmission gears, moderate speed, representing the highest level of integration within the plastic-housing series. 🛤️ Linear Guide Systems (FDA/FDB/FDC… series) Franke’s linear guide systems are also based on the “wire-track” concept, embedding hardened wire raceways within an aluminum profile frame. Their naming convention is straightforward: typically consisting of a “series code + version suffix,” such as FDA-K or FDC-R. FDA (Standard Type): Basic aluminum needle-guide rail, offering smooth and quiet operation. FDB (Economy Type): Economical aluminum roller guide, ideal for cost-sensitive applications. FDC (Corrosion-Resistant Type): Featuring stainless-steel raceways, highly resistant to corrosion, suitable for humid or chemically aggressive environments. FDD (Non-Magnetic Type): Non-magnetic design, perfect for medical equipment (such as MRI) and electronics manufacturing environments. FDE (Maintenance-Free Type): Maintenance-free design, eliminating the need for additional lubrication, making it ideal for food production or cleanroom applications. FDG (Corrosion-Resistant Economy Type): Combines corrosion resistance with cost-effectiveness, designed for cost-sensitive applications in harsh environments. FDH (High-Dynamic Type): Specifically engineered for high acceleration and high speed, delivering exceptional dynamic pick-and-place performance with accelerations up to 100 m/s². FDI (Vacuum-Compatible Type): Materials and design prevent outgassing in high-vacuum environments, making it suitable for vacuum equipment. 🍽️ Precision Workstations (LTA/LTB/FTB/FTC/FTD series) These products are more fully functional units, integrating not only drive mechanisms (motors, worm gears, lead screws, etc.) but also guiding and load-bearing functions into a single package, making them “plug-and-play” core components for building equipment. LTA / LTB (Rotary Tables): High-precision rotary positioning platforms, with LTB offering even higher accuracy, primarily used for measurement and inspection tasks. FTB / FTC / FTD (Linear Platforms/Modules): FTB: spindle-driven, ideal for measurement, testing, and positioning tasks requiring precise process control. FTC / FTD: belt-driven, specifically designed for high-speed, rapid positioning applications. 💡 Selection Tips Clearly define your integration approach: For maximum design freedom, choose bearing components (LEL/LER/LEW, etc.); for convenience and speed, opt for bearing assemblies (LVC/LVD/LVK, etc.). Focus on key performance criteria: For high precision/high speed, select the LVC, LDD, or LDL series; for heavy loads/high rigidity, go with the LED, LVG, or LEW series; for cost-effectiveness, consider the LER, LVK, or FDB series. Account for special environments: Choose FDC/FDG for humid/corrosive conditions; FDE for food/medical applications; FDD for strong magnetic fields like MRI; and FDI for vacuum environments. Leverage official resources: Franke’s website offers free CAD model downloads that can be imported into 3D design software to verify compatibility. Their engineering toolkits and product samples are also invaluable aids for selection. Are you currently preparing to design and select components, or are you just doing some preliminary research?
