3. Key Advantages
  • Three-piece separable split design, convenient independent disassembly, installation and regular maintenance inspection
  • Only bears pure unidirectional axial thrust load, delivers high axial rigidity under continuous static & light impact load
  • Precision deep raceway grooves lock steel balls evenly, reduce sliding friction and stable low-noise operation
  • Compact thin overall height saves axial installation space for small vertical mechanical structures
  • Standard metric ISO size, fully interchangeable with universal aftermarket replacement thrust bearings
  • Optional upgrades: stainless steel anti-rust version, P6/P5 high precision grade, self-aligning housing washer

Eliminates axial shaft floating and improves positioning stability of vertical rotating equipment

4. Appliions
