Thin Section Four-Point Contact Ball Bearing CSXA040 101.6×114.3×6.35mm for Precision Robotics

Thin Section Four-Point Contact Ball Bearing CSXA040 101.6*114.3*6.35mm for Precision Robotics & Medical Equipment

The CSXA040 Thin Section Four-Point Contact Ball Bearing is engineered for high-precision, space-critical applications requiring minimal weight and maximum structural rigidity. Featuring an extremely compact cross-section relative to its diameter, this single-row four-point contact design allows a single bearing to accommodate axial, radial, and moment loads simultaneously in both directions. It is widely used in advanced robotic joints, aerospace components, semiconductor manufacturing, and diagnostic medical equipment where space-saving envelopes and exceptional running accuracy are strictly required.

• Ultra-Thin Space Saving Envelope: Delivers top-tier mechanical stiffness within a compact 1/4" (6.35mm) cross-section, drastically lowering housing weight.
• Multi-Directional Load Management: Unique four-point contact geometry behaves like paired configurations, managing complex combined radial and thrust loads.
• High Operational Accuracy: Premium-grade manufacturing controls eliminate run-out, ensuring smooth rotation and uniform precision torque.
• Premium GCr15 Steel Composition: Advanced induction hardening increases core toughness and fatigue resistance under demanding work cycles.
• Rigid Sheet Metal Brass Cage: Specialized low-friction brass cage guides rolling elements reliably while minimizing rotational noise and vibration.

• Q1: Can the CSXA040 bearing replace a pair of standard angular contact bearings?
  Yes. Due to its specific four-point contact geometry, a single CSXA040 bearing can support combined loads (radial, axial, and moment) from both directions simultaneously. This allows it to replace a traditional face-to-face or back-to-back duplex bearing pairing, saving considerable space and weight.
• Q2: Does your factory provide alternative configurations for the CSXA040 model, such as stainless steel or ceramic balls?
  Yes. For highly specialized environments, we can custom-manufacture this model using stainless steel rings (for corrosive settings) or equip it with silicon nitride ceramic balls (hybrid ceramic configuration) for lower friction and ultra-high-speed cleanroom requirements.
• Q3: What quality certificates does your factory hold for international automation shipments?
  Our production facilities are fully certified under ISO 9001:2015 global quality management guidelines. We implement rigid dimensional traceability control loops to verify that every thin-wall batch strictly adheres to uniform tolerance limits.
• Q4: How do you safeguard thin-section bearings like CSXA040 from bending or damage during transit?
  Thin-section bearings require gentle handling since their slim rings are more sensitive to distortion. We place every bearing inside custom-cut shock-absorbing protective foam plates, vacuum-seal them in anti-static moisture-barrier bags, and crate them in structural plywood cases.
