Air Bearings Air bearings use a thin film of pressurized air to separate bearing surfaces, delivering near frictionless linear motion with stiffness. They support precise positioning with minimal wear, enabling longer life and lower operating costs in demanding applications. Key benefits Ultra low friction and smooth motion for fast response and repeatability stiffness and load retention under dynamic conditions Very low wear, enabling long service intervals and stable results No contact seals or lubrication required in many configurations, reducing maintenance and contamination risk Compact, modular design that integrates with standard machine tools and stages Broad compatibility with common mounting patterns and interfaces used in precision equipment Consistent performance over the designed temperature range What to expect Function: provides frictionless support and guidance for linear motion with geometric accuracy Compatibility: available in multiple mounting footprints and interface options to suit standard precision equipment Size: offered in a range of sizes to match load, travel, and footprint requirements Material: precision machined metal components with polished bearing surfaces designed for durability Performance: low friction, stiffness, low runout, and predictable behavior under load Use scenarios Precision metrology and optical alignment stages where micron level repeatability is required precision CNC slides and milling or grinding equipment for smooth, rapid positioning Semiconductor wafer handling and microassembly in controlled environments needing low wear and stability Selection tips Identify required load rating, travel distance, and stiffness; select a model with adequate capacity for your machine Check mounting patterns and interface compatibility with your existing stage or tool Consider environmental conditions and cleanliness; ensure sealing and materials meet application needs Plan integration with control systems; confirm availability of feedback options if needed Maintenance and care Keep air supply clean and dry; ensure filters are maintained to protect the bearing surfaces Inspect surfaces and seals regularly for signs of wear or contamination Follow manufacturer guidelines for installation, alignment, and periodic maintenance
