Type-A thin-section angular contact ball bearings are ultra-slim,constant cross-section rotary components featuring inclined raceways. Engineered to simultaneously handle combined radial and unidirectional axial loads,they are ideal for compact,lightweight,high-precision equipment with space constraints.
Semiconductor and precision automation equipments are high-end ultra-clean manufacturing and testing equipment applied in chip fabrication,wafer processing,electronic component assembly and precision measurement industries. Core equipment covers wafer transfer robots,EFEM loadports,lithography exposure machines,etching & deposition vacuum chambers,semiconductor inspection turntables,SMT precision placement machines,optical inspection automation lines,multi-axis precision indexing tables and micro-component sorting automation equipment. All rotary joints,rotating platforms and manipulator arms of these devices work in strict ultra-clean or high-vacuum environments,with extremely demanding operating standards:zero particle shedding,ultra-low outgassing,nanoscale repeated positioning accuracy,minimal rotation vibration and long-term stable continuous operation. In the production process,rotary bearings need to bear alternating radial self-weight of manipulators,unidirectional axial thrust of micro servo motors and frequent small overturning loads. Ordinary standard bearings have large wall thickness,heavy mass,high dust generation and large rotation backlash;tiny vibration or lubricant volatilization will scratch silicon wafers,pollute optical lenses and lead to mass chip scrapping. Therefore,thin section angular contact ball bearings become the core rotary supporting parts for all semiconductor and precision automation equipment.
Constant Cross-Section Design
Space & Weight Saving:Unlike standard ISO series bearings-where cross-sectional height increases as bore size increases-thin section bearings maintain a fixed,extremely narrow cross-section regardless of the shaft diameter.
Compact Footprint:This constant geometry drastically reduces envelope dimensions,overall assembly weight,and rotational inertia without sacrificing shaft diameter size,reserving large hollow inner holes for clean gas pipelines,optical fiber and internal signal wiring of semiconductor manipulators.
High Axial (Thrust) Load Handling in One Direction
Contact Angle Geometry:The inner and outer ring raceways are displaced relative to each other along the bearing axis,typically creating a 15°,25° or 40° contact angle.
Combined Loads:This geometry enables the bearing to support high thrust loads in one direction,alongside concurrent radial loads.
Duplex Configurations:To support bidirectional thrust loads or increase joint rigidity,these bearings are frequently mounted in back-to-back (DB),face-to-face (DF) paired arrangements inside vacuum rotary stages and robot wrist modules.
Precision & High Rigidity
Preload Capability:Thin section angular contact bearings can be ground for light,medium or heavy preloading. Preloading removes internal clearance and mechanical backlash,eliminating arm wobble during wafer slow-speed positioning and optical scanning.
Smooth Rotational Accuracy:Ultra-precision mirror superfinishing ensures minimal rotational runout,realizing micron-level repeated positioning required for wafer pick-and-place and electronic component inspection.
Low Friction & Low Torque
Small Rolling Elements:Miniature steel or ceramic balls cut centrifugal force and rolling resistance greatly.
High-Speed Efficiency:Low friction generates little heat during long-cycle reciprocating rotation,effectively reducing grease volatilization and particle precipitation inside sealed vacuum chambers to meet cleanroom production standards.

Ultra-Thin Lightweight Structure Optimizes Miniaturized Equipment:Layout Semiconductor equipment internal cavity space is extremely limited,with dense optical components,vacuum pipelines and sensor cables. Thin section angular contact ball bearings reduce component weight by over 40% compared to same-bore standard bearings,greatly shrink radial installation space,simplify the integrated structural design of wafer manipulators and vacuum rotary tables,and shorten equipment R&D and prototype trial production cycles.
Low-Outgassing & Low-Particle Performance Avoid Wafer Contamination:Custom 440 stainless steel and ceramic hybrid bearing bodies,matched with special vacuum low-outgassing clean lubricants,will not volatilize harmful substances or shed tiny particles in high-vacuum and Class 1 ultra-clean environments. Fully non-contact shielding structures block internal abrasion dust,fundamentally eliminate wafer scratch and chip pollution risks,and effectively improve semiconductor product yield.
Preloaded Zero-Backlash Design Guarantees Nanoscale Position Accuracy:Wafer transfer and chip inspection require ultra-stable rotation without jitter. Preloading technology completely eliminates bearing internal clearance and micro-play,restrains tiny vibration generated by high-frequency reciprocating movement,ensures consistent motion track of manipulators,and realizes sub-micron repeated positioning to meet the ultra-high precision demands of lithography and wafer detection processes.
Composite Load Bearing Simplifies Modular Mechanical Design:A set of paired thin bearings can simultaneously bear radial manipulator weight,axial servo thrust and small overturning moment during wafer transfer,replacing multiple groups of separated radial and thrust standard bearings. It reduces the quantity of mechanical parts inside rotary modules,lowers equipment assembly and calibration difficulty,and cuts manufacturing and after-sales maintenance costs of automation equipment.
Wide Environment Adaptability Fits Vacuum & Constant-Temperature Workshops:Special customized low-temperature stable clean grease adapts to 20-26℃ constant-temperature semiconductor workshops and high vacuum sealed chambers,with no grease failure after long-term uninterrupted production. Stainless steel material resists trace corrosive process gas,extending the continuous service life of bearings in etching and deposition equipment.
Excellent Anti-Fatigue Performance Reduces Production Line Downtime:Raceways and rolling elements adopt deep hardening treatment with surface hardness HRC55-62,possessing outstanding anti-wear and anti-fatigue performance,capable of enduring tens of millions of wafer transfer cycles without precision attenuation. Frequent equipment shutdown for bearing replacement is drastically reduced,maximizing the operating efficiency of semiconductor production lines.
