Nut/carriage Component – Machinery and Equipment Manufacturing

Q: What is the difference between a nut/carriage and a ball screw assembly?

Nut/carriage assemblies typically use acme or trapezoidal threads for cost-effective applications with moderate precision, while ball screw assemblies use recirculating balls for higher efficiency and precision in demanding applications

Q: How do I select the right nut/carriage for my application?

Consider load requirements, speed, precision needs, environmental conditions, and maintenance requirements. Consult manufacturer specifications for dynamic load ratings, backlash tolerance, and lubrication requirements

Component Specifications

Definition

A mechanical assembly consisting of a nut that engages with a lead screw and a carriage that provides mounting and guidance, designed to convert the rotary motion of a motor-driven screw into precise linear movement in industrial machinery

Working Principle

The nut contains internal threads that mesh with the external threads of a lead screw. When the screw rotates, the nut travels linearly along the screw axis. The carriage provides structural support, maintains alignment, and often includes guidance features to ensure straight-line motion with minimal deflection

Materials

Nut: Bronze (C93200), Steel (AISI 4140), or Polymer composites; Carriage: Aluminum alloy (6061-T6) or Steel (AISI 1045); Fasteners: Grade 8.8 or higher steel

Technical Parameters

Backlash <0.05 mm
Thread Pitch 2-10 mm
Travel Speed 0.1-2 m/s
Load Capacity 500-5000 N
Repeatability ±0.01 mm
Operating Temperature -20°C to 120°C

Standards

ISO 3408, DIN 69051, JIS B1192
