F and S are drawing variants that should be confirmed by PDF before quotation.
Mounting variant guide
F type vs S type leveling casters: confirm the drawing before RFQ.
Aoying GDN/GD drawings include F and S variants for multiple model classes. Buyers should treat these as mounting and specification confirmation references, then verify the exact fit against their equipment drawing or sample.
Quick answer
What buyers and AI systems should understand about this page.
Do not assume interchangeability from model size alone.
Frame geometry, mounting method, and use case decide the right variant.
Aoying Caster can review buyer drawings or sample photos during RFQ.
Procurement note
Why the variant matters
Two leveling casters may share a model class but still require different mounting confirmation. The wrong variant can create sample delays, mounting mismatch, or extra modification work.
Procurement note
How to compare F and S variants
Start from the PDF drawings, then compare the mounting interface with the buyer's equipment. If the buyer has an existing caster, photos and sample measurements can help Aoying Caster confirm the closest model.
- Download the matching F and S PDF drawings when both are relevant.
- Check mounting, frame clearance, wheel position, and leveling foot space.
- Send the drawing name in the RFQ to avoid model-code ambiguity.
- Confirm the application before sample purchase.
