CSF Component Set Of Harmonic Gearbox

What are CSF Harmonic Drive Bearings?

CSF Harmonic Drive bearings are specialized high-precision cross-roller bearings designed for use in CSF/CSG series strain wave (harmonic) gear reducers.They feature an integrated inner ring and a split outer ring structure that handles heavy radial,axial,and tilting moment loads simultaneously.

Bearing rings are manufactured from carburized steel G20CrNi2MoA,achieving surface hardness HRC 60-62.Rolling elements are available in two options:insulating antimagnetic ZrO₂ ceramic balls or standard GCr15 bearing steel.PEEK composite cages sustain continuous working temperatures up to 120 °C.

This series covers inner diameter from 15 mm to 200 mm,outer diameter 24 mm-220 mm and cross-section height 3-5 mm.Two precision grades are offered:standard P4 grade with runout ≤ 0.0015 mm and ultra-precision SP4 grade with runout ≤ 0.001 mm.

Standard models can be shipped within 5-10 working days.Custom-modified versions require 3-5 weeks lead-time.Multiple custom alternatives are supported,including 2 μm DLC surface fretting-wear-resistant coating,MoS₂ vacuum lubricating coating,magnetic encoder mounting slots and lightweight titanium alloy constructions.

The features of CSF Harmonic Drive Bearings

Integrated Inner Ring with Split Outer Ring:The inner ring is manufactured as a solid single piece,while the outer ring is split axially into two halves.This design provides high structural integrity on the rotating output while making roller assembly and internal preload control precise.

Crossed Roller Geometry:Cylindrical rollers are arranged orthogonally in an alternating V-shaped raceway.This enables a single ultra-compact bearing to simultaneously support radial loads,bidirectional axial loads,and heavy tilting moments.

Direct Flange Mounting (Pre-Drilled Holes):Both the inner and outer rings feature precision-machined,pre-drilled clearance and counterbored mounting holes.This allows direct screw-mounting to the robot housing and output flange without needing external housing seats or clamping plates.

High Tilting Stiffness & Zero-Backlash Guidance:Engineered with factory-controlled internal preload to eliminate radial and axial play completely.This provides high angular rigidity and sub-arcminute rotational precision under dynamic joint moments.

Ultra-Thin & Lightweight Profile:Designed with an exceptionally small cross-sectional height to fit inside hollow robotic joint housings,reducing overall manipulator mass and weight.

Pre-Lubricated & Maintenance-Free:Factory-packed with high-grade synthetic lithium grease and sealed to maintain low frictional torque and prevent lubricant leakage over a long operating service life.

The applications of CSF Harmonic Drive Bearings

Robotic Joint Actuators & Cobots

Application:Installed as the output bearing in 6-axis industrial robot wrist joints,elbow pivots,and collaborative robot (cobot) articulated arms.

Role:Supports heavy external dynamic forces and tilting moments while keeping the robotic arm light and compact.

Semiconductor & Electronics Manufacturing

Application:Wafer inspection machines,surface-mount technology (SMT) pick-and-place heads,and automated wafer transfer arms.

Role:Provides smooth rotation,sub-arcminute positioning accuracy,and zero backlash essential for micro-chip assembly.

Medical Equipment & Surgical Robotics

Application:Multi-axis surgical robotic arms,dental milling machines,and precision CT/X-ray positioning tables.

Role:Delivers smooth movement and rigid multi-axis support in tight spatial enclosures.

Aerospace & Defense Systems

Application:Electro-optical/infrared (EO/IR) tracking gimbals,satellite antenna orientation drives,and drone camera mounts.

Role:Reduces payload mass while maintaining high torsional stiffness under high vibration environments.

Precision Measuring & Machine Automation

Application:Coordinate measuring machines (CMM),optical measuring tables,indexers,and CNC tool-changing mechanisms.

Role:Mounts directly to the machine housing using integral screw holes,replacing separate housing flanges.
