Description
1. Self-aligning Capability: Features front-mounted X-type (45°×45°) arc raceway groove design with automatic alignment compensation. The internal mechanism absorbs minor mounting surface deviations to maintain high-precision, smooth, and stable linear motion.
2. High Rigidity Four-Directional Equal Load Design: Incorporates 4-row ball circuits with 45° contact angle configuration, achieving optimal two-point contact for bidirectional radial/lateral load capacity. Optional preload application enhances system rigidity when required.
3. Interchangeability: Stringent manufacturing precision ensures dimensional consistency within stable tolerances. Integrated retainer design prevents ball dislodgement, enabling between and matching guideways while preserving operational smoothness, preload integrity, and motion accuracy.

  • Mounting holes: M6 threaded (pitch: 60mm between holes)
  • Material: GCr15 bearing steel (HRC 58-62) with black oxide coating
  • Temperature range: -20℃ to 100℃
  • Weight: 3.4kg (rail) + 0.5kg/carriage = Total 4.4kg
  • Dimensions: 780mm(L) × 45mm(W) × 34mm(H)

High-rigidity linear motion system with optimized ball circuit design for smooth operation under heavy loads. Features corrosion-resistant treatment and multi-stage sealing for harsh environments. The F2 flange type allows for compact machine design with space-saving vertical mounting.

Typical Applications:
  • CNC gantry mill Z-axis guidance systems
  • Automated warehouse stacker cranes
  • Semiconductor wafer handling robots
  • High-speed packaging line transfer units
  • Precision optical inspection equipment
Installation notes:
1. Use torque wrench (recommended 5.5-6.5N·m for M6 screws)
2. Align with reference edge within 0.02mm/m straightness
3. Apply lithium soap-based grease to raceways before operation
4. Avoid side load exceeding 15% of vertical capacity
