Precision crossed roller bearings are high-precision mechanical components characterized by cylindrical rollers arranged perpendicularly (at 90°) to each other between the inner and outer rings.This unique structure allows a single bearing to simultaneously withstand radial loads,axial loads,and overturning moments without needing multiple bearing combinations.They feature an extremely slim cross-section,miniaturized and lightweight design,consistent with the high-precision philosophy of thin-section bearings.Made with bearing steel,stainless steel,or ceramic materials,they are manufactured to precision grades ranging from ABEC 1 to ABEC 7,with tolerances as tight as P5/P4 level through precision cold ring rolling and super-fine grinding processes.With low friction,high rigidity,and minimal rotational runout,they are widely used in high-end precision equipment.
A precision rotary table is a high-accuracy rotary positioning platform designed to achieve stable,precise rotation and micron-level positioning accuracy.It serves as a core motion unit in precision machinery,requiring extremely high standards for rotational stability,positioning repeatability,and space utilization.Precision rotary tables are widely used in scenarios such as precision measuring instruments,semiconductor manufacturing equipment,optoelectronic systems,aerospace devices,medical machinery,and industrial robots.They need to maintain stable rotation under limited space and complex loads,while ensuring long-term operational reliability and consistent performance-all of which place strict demands on their core supporting components.
Precision crossed roller bearings are the core foundational components of precision rotary tables,and their performance directly determines the table's precision,rigidity,and service life.
High composite load capacity:The crossed roller structure enables the bearing to carry radial,axial,and moment loads at the same time,replacing complex combinations of multiple bearings to simplify the rotary table structure and reduce assembly errors.
Ultra-high rotational accuracy:With micron-level rotational runout and optimized raceway grinding,they ensure the precision rotary table achieves stable,low-deviation rotation and high-precision positioning,meeting the strict accuracy requirements of precision machining and measuring equipment.
High rigidity and anti-overturning performance:Line contact between rollers and raceways delivers high rigidity,effectively suppressing deflection and overturning under offset loads or heavy working conditions,keeping the rotary table stable during operation.
Compact and space-saving:The slim cross-section design matches the miniaturization and lightweight requirements of precision rotary tables,saving installation space while maintaining excellent performance.
Smooth operation and long service life:Low-friction geometry reduces torque,heat,and energy consumption.Combined with strict quality control and precision manufacturing,the bearings deliver stable performance and a long service life for the rotary table.
