Adjustment Screw/Spindle Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

A threaded screw or spindle designed specifically for pressure adjustment mechanisms, enabling precise calibration of force, tension, or compression in industrial equipment through controlled linear displacement.

Working Principle

Utilizes screw thread mechanics to convert rotational motion into precise linear movement, adjusting the position of connected elements to modify pressure settings within the mechanism.

Materials

Typically made from alloy steel (e.g., AISI 4140), stainless steel (e.g., 316SS), or hardened carbon steel with corrosion-resistant coatings like zinc plating or black oxide.

Technical Parameters

Length 50-200 mm
Diameter 6-20 mm
Tolerance ISO 2768-m
Thread Type Metric (e.g., M8x1.25) or Unified (e.g., 1/4-20)
Thread Pitch Fine (0.5-2.0 mm)
Load Capacity 500-5000 N
Surface Finish Ra 1.6-3.2 μm

Standards

ISO 965, DIN 13, ISO 898-1

Frequently Asked Questions

What is the difference between an adjustment screw and a regular screw?

Adjustment screws have finer threads, tighter tolerances, and are designed for precise linear positioning rather than just fastening.

How often should adjustment screws be maintained?

Lubricate every 500 operating hours and inspect for wear every 6 months, depending on usage intensity.

Can adjustment screws be used in high-temperature environments?

Yes, when made from heat-resistant alloys like A286 stainless steel with appropriate coatings.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
