Adjustment Screw / Mechanism: Load Capacity 500-2000kg

Component Specifications

Definition

A threaded mechanical component designed to provide fine, controlled linear or angular adjustments to the position of rollers within a straightening bank. It enables precise calibration of roller spacing, pressure, and alignment to ensure uniform material processing and dimensional accuracy during straightening operations.

Working Principle

Utilizes screw thread mechanics to convert rotational motion into precise linear displacement. Turning the screw advances or retracts the mechanism, adjusting roller position relative to the machine frame. Fine-pitch threads provide high resolution for micro-adjustments, while locking mechanisms maintain position under operational loads.

Materials

High-strength alloy steel (e.g., AISI 4140, 4340) with surface hardening (HRC 45-50) for wear resistance. Corrosion-resistant coatings (zinc plating, black oxide) or stainless steel (AISI 304, 316) for harsh environments.
