💡 Why choose thrust ball bearings?
Because they’re built for strength under pressure:
- Ideal for applications with heavy axial loads but minimal radial force
- Provide smooth, stable movement under compression
- Commonly used in gearboxes, turntables, and rotating machinery

Compact, tough, and reliable, these 12x21x5mm thrust bearings keep your motion systems stable when the pressure’s on.
