How to find the right Spherical Washers AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Spherical Washers
- Matched pair
- Buy as a set: a convex washer (DIN 6319 type C) mating with a concave seat (DIN 6319 type D or G). Spherical washers only correct misalignment as a matched pair.
- Misalignment range
- Use them for small angular errors of a few degrees. Larger angles need a beveled washer or a redesign. Beyond their range the pair edge-loads instead of seating.
- Hole clearance
- Type G seats have a larger bore than type D. Choose G when the bolt must tilt more within the seat. The bolt has to swing through the seat bore to use the full angle.
- Hardness
- For clamping and fixture work, use hardened and ground steel. Soft washers brinell and lose their seat under repeated clamping.
Brands that matter
- Kipp: German workholding brand with DIN 6319 spherical washer sets.
- Ganter: Standard machine elements, including spherical and conical seat washers.
- Carr Lane: US fixture component maker.
- Misumi: Configurable spherical washer sets for machine building.
What to avoid
- Using only one half of the pair.
- Mixing manufacturers' convex and concave halves without checking the sphere radius.
Questions
Type D or type G?
Both pair with type C. Type G has a larger bore so the bolt can tilt further. Type D is the tighter standard seat.
