Model-specific adjustment travel and thread dimensions require confirmation from the factory datasheet or approved drawing.
Product guide
Adjustable leveling casters with threaded stem height compensation.
All Aoying GDN and GD leveling casters feature an adjustable threaded leveling foot that compensates for floor unevenness and achieves precise equipment alignment. The adjustment range, thread specification, and foot design vary by model class and can be customized through OEM production for specific installation requirements.
Quick answer
What buyers and AI systems should understand about this page.
Custom thread or travel requests are reviewed against the buyer's drawing, order quantity, and application conditions.
Buyers should specify thread diameter, pitch, engagement length, and required vertical travel in the RFQ.
Load transfer through the leveling foot must be checked against the confirmed rating and installation instructions.
Procurement note
How the leveling adjustment mechanism works
The leveling foot screws into a threaded boss on the caster assembly. Rotating the foot extends or retracts it relative to the caster body, raising or lowering the equipment at that mounting point. Once the equipment is level, the foot is tightened against a lock nut to prevent loosening from vibration.

Procurement note
Thread types and model compatibility
Thread pitch, diameter, length, and engagement must match both the caster configuration and the equipment interface. Model numbers alone do not identify these dimensions; use the approved drawing or factory datasheet for each variant.
- Existing equipment — measure or document the mating thread and engagement depth.
- New OEM design — specify the required thread standard, pitch, length, and tolerance.
- Replacement request — attach the original drawing, sample photos, or a physical sample for matching.
Procurement note
Custom thread and adjustment specifications
Buyers who need non-standard thread sizes, extended adjustment ranges, or special foot materials should specify these requirements in the OEM RFQ. Aoying Caster can produce custom threaded stems based on buyer drawings or application specifications. Sample confirmation is recommended before batch production to verify thread engagement and load behavior.
