Moving Carriage/Platform for Linear Positioning Stages

Product Specifications

Technical details and manufacturing context for Moving Carriage/Platform

Definition

A moving carriage or platform is the core load-bearing element within a linear positioning stage system. It provides the mounting surface for tools, workpieces, or sensors and is precisely guided along linear rails or shafts by bearings. Its primary role is to translate the motion from a drive mechanism (like a leadscrew or linear motor) into accurate, repeatable linear positioning of the payload. The carriage is typically made from aluminum alloy, stainless steel, or carbon steel, with material selection based on rigidity, weight, and environmental requirements. Key parameters include load capacity (50–500 kg), stroke length (100–2000 mm), positioning accuracy (±0.01–±0.05 mm per ISO 230-2), repeatability (±0.005–±0.02 mm per ISO 230-2), maximum speed (0.5–2 m/s), and operating temperature (-10 to 60 °C). Drive types can be ball screw, belt, or linear motor, while guideway types include linear guide or dovetail. Protection class ranges from IP40 to IP65 per IEC 60529. The carriage weight varies from 10 to 150 kg. These values are reference ranges and must be verified with the manufacturer for specific models and applications. The carriage interfaces with the drive mechanism and guideway, and its design affects inertia and mounting requirements. Proper selection requires considering load, speed, precision, and environmental conditions. Maintenance signals include increased friction, noise, or play, indicating wear or lubrication issues. Failure boundaries include exceeding load capacity or operating temperature, which can lead to premature wear or failure. Always consult the supplier for model-specific specifications and compliance.

Working Principle

The carriage is rigidly attached to the drive mechanism's nut or motor forcer. When the drive mechanism is actuated, it applies a force to the carriage. This force is transferred through the carriage's integrated bearing blocks (e.g., linear ball bearings, crossed roller bearings) that ride on precision-ground guideways (rails or shafts). This bearing interface constrains motion to a single linear axis with minimal friction and play, allowing for smooth, precise translation of the mounted payload.

Frequently Asked Questions

What is the load capacity range for this moving carriage?

The load capacity is listed as 50–500 kg at rated speed and life. However, the actual capacity depends on the specific model, guideway type, and operating conditions. Always verify with the manufacturer for your application.

What drive types are compatible with this carriage?

The carriage can be used with ball screw, belt, or linear motor drives. The choice depends on speed, precision, and load requirements. Confirm compatibility with the supplier.

What is the positioning accuracy and repeatability?

Positioning accuracy is ±0.01 to ±0.05 mm, and repeatability is ±0.005 to ±0.02 mm, both per ISO 230-2. Higher accuracy may require ball screw or linear motor drives. Verify with the manufacturer for the exact model.

What materials are available for the carriage?

The carriage can be made from aluminum alloy, stainless steel, or carbon steel. Aluminum is lighter, while steel offers higher rigidity. The choice affects weight and performance. Confirm material options with the supplier.
