⚙️Product Description:

The JU065XPO / CSXU065-2RS (165.1 x 184.15 x 12.7 mm / 6.5 x 7.25 x 0.5 in) is an extra-lightweight, high-precision thin section four-point contact ball bearing (“X” type Gothic arch raceway) engineered specifically for robotic articulation joints and space-constrained rotary bases. Designed within the ultra-slim 12.7mm (1/2 inch) cross-sectional profile, a single JU065XPO unit replaces multi-bearing arrangements by simultaneously sustaining complex radial loads, double-direction axial forces, and heavy overturning moment loads. Available in open type (JU065XPO) or sealed type (CSXU065-2RS) with low-friction contact seals, we supply these space-saving thin section bearings under our proprietary RMO brand while facilitating multi-brand OEM direct sourcing for global industrial robotics, semiconductor arms, and medical automation builders.

RMO brand JU065XPO thin section bearings

⚙️Product Features:

  • Gothic Arch Four-Point Contact Geometry: Unique 4-point raceway contact angle allows a single compact bearing to sustain combined radial, thrust, and heavy moment loads simultaneously.
  • Ultra-Slim 12.7mm Constant Cross-Section: Maintains a minimal 1/2-inch cross-sectional height across a large 165.1mm (6.5 in) inner bore, drastically saving robotic joint space and mass.
  • Multi-Bearing System Consolidation: Replaces traditional pairs of angular contact or tapered roller bearings, simplifying housing design and assembly alignment.
  • Sealed & Pre-Lubricated Options: CSXU065-2RS contact seals retain long-life synthetic grease and shield precision raceways against cleanroom dust and particulate entry.

⚙️Product Application:

Engineered for compact robotic integration, moment load resistance, and low mass inertia, the JU065XPO thin section bearing is widely specified in:

  • Industrial robotics & automation: 6-axis robot waist & shoulder joints, SCARA arm bases, and collaborative robot (cobot) rotators.
  • Semiconductor & cleanroom equipment: wafer handling robotic arms, vacuum chamber rotators, and liquid crystal transfer gantry joints.
  • Medical & optical platforms: surgical robot manipulator arms, CT scanner rotating gantry mounts, and satellite optical trackers.
  • Precision rotary stages: hollow rotary indexing tables, radar antenna mounts, and multi-axis gimbal camera rigs.

⚙️Precautions:

1. Keep clean2. Use with caution3. appropriate tool4. Hot-loading5. Be careful of rust
Dust will have a bad effect on the bearing, so keep the surrounding clean.Strong impact during use can easily cause scratches and indentations.Avoid replacing existing tools, and use appropriate tools.Bearings are precision parts, so hot installation is recommended.Sweat on your hands during operation will cause rust, so it is best to wear gloves.
