This metal-ball family offers material-named selections including 201, 304, 316 and 440 stainless steel. Confirm the size and finish for the chosen material.
Choose the actual ball material
The option is named Color but contains material descriptions, including tantalum, copper, tungsten steel, titanium and bearing steel. Keep the selected material explicit; a property of one option should not be assigned to every ball.
- Four named stainless grades are selectable.
- Fine polishing is a surface description.
- Diameter is not a separate selectable option.
Confirm diameter and surface treatment
The title references 16, 20, 25, 30 and 35mm. Request the actual diameter, tolerance and any plating requirement rather than assuming all material choices have those sizes and finishes.
Evaluate the intended mechanism
Bearing, screw-rod and guide-rail contexts need assembly-specific acceptance criteria. Hardness is not specified numerically, and corrosion or wear resistance requires evidence for the chosen material and surface condition.
