Get a Robotics Bearing Selection PlanThe flexspline carries load through elastic deformation, requiring bearings with thin walls, high fatigue life and rotational accuracy.
Recommended: Flexible Thin-Wall Bearings · Crossed Roller Bearings · Four-Point Contact Bearings
Withstands impact and torque loads, requiring bearings with high rigidity, impact resistance and long service life.
Recommended: Tapered Roller Bearings
High torque density compact transmission; requires high load capacity, high rigidity, impact resistance and long life.
Recommended: Tapered Roller Bearings · Deep Groove Ball Bearings
Joint slewing support requiring compound load capacity, zero backlash and high positioning accuracy.
Recommended: Flexible Thin-Wall Bearings · Crossed Roller Bearings
High-speed rotary drive requiring low noise, low vibration and high-speed stability.
Recommended: Deep Groove Ball Bearings
Fingertip joints demand miniaturization, requiring extremely small size, low friction and high sensitivity.
Recommended: Miniature / Extra-Miniature Bearings (bore diameter from 1mm)
Crossed roller rotational accuracy ≤0.005mm, meeting P4 / P2 ultra-precision grades to ensure joint positioning and repeatability accuracy.
Crossed rollers arranged at 90° enable compound load capacity, simultaneously carrying radial, axial and moment loads with strong deformation resistance.
Precision-ground raceways and premium bearing steel deliver a low friction coefficient and minimal vibration, ensuring smooth servo response and controllable noise.
Batch-to-batch consistency control and fatigue life optimization meet the high-reliability demands of continuous, long-duration robot operation.
Flexible thin-wall bearings reduce weight by 30%-50% while maintaining rigidity, effectively lowering joint inertia and improving response speed.
