Precision measuring instruments are high-end equipment used to obtain accurate dimensional data,geometric tolerances and position parameters,mainly including coordinate measuring machine (CMM) rotary tables,optical and laser scanning devices,precision detection platforms and high-precision positioning measuring equipment.These instruments have ultra-strict requirements for rotating parts:nanometer-level positioning accuracy,zero backlash,ultra-low vibration and stable rotation,compact structure for limited space,and long-term stable operation.The precision of rotating bearings directly determines the final measurement accuracy of the whole instrument,and tiny deviations will lead to wrong measurement results.
RA crossed roller bearings are core rotary support parts of precision measuring instruments,and their performance is the key to ensuring measurement accuracy and stability.
Ultra-high rotational precision for accurate measurement:With P4-level precision and run-out tolerance ≤0.002mm,they achieve nanometer-level positioning,which directly improves the measurement accuracy of CMM rotary tables and ensures error-free detection data.
High rigidity to suppress deformation:The crossed roller layout maximizes contact area and reduces deformation,providing stable support to avoid deflection during measurement,which is critical for high-precision dimension detection.
Composite load capacity simplifies structure:They can bear radial,axial and overturning moment loads at the same time,replacing complex bearing combinations,reducing assembly errors and adapting to the compact design of precision measuring instruments.
Low friction and low vibration:Optimized roller end geometry reduces sliding friction and vibration,ensuring jitter-free rotation of mirrors and sensor mounts in optical and laser scanning devices,avoiding measurement interference.
Compact thin-section design:The thin-section structure (minimum section height 8mm) saves installation space,matching the miniaturized and integrated design of precision measuring instruments.
Long service life and stable performance:Homogeneous materials and surface hardening treatment (HRC 60-62) enhance fatigue resistance,meeting the long-term continuous operation requirements of precision measuring instruments.
