Cost Optimized PTH Series Semi Enclosed Screw Modules High Precision & High Rigidity

1.Product Overview

The PTH series semi-enclosed screw modules are linear transmission components designed for balancing precision and practicality. Adopting a semi-enclosed structure and precision ball screw technology, they integrate three core advantages: "flexible protection, high-precision positioning, and cost-effectiveness". While retaining sealed protection for critical components, the modules feature an open maintenance design to simplify upkeep, accommodating 20-200kg load requirements. They are widely applied in industrial scenarios with moderate environmental cleanliness demands but requiring precision, balancing performance and cost efficiency.

2.Core Selling Points

Semi-Enclosed Flexible Protection

IP54 dust and water resistance: Equipped with an integrally formed profile shield + single-side sealing design, it blocks large particulate dust and splashing liquids. Meanwhile, it facilitates quick disassembly and inspection of internal components, with maintenance efficiency improved by 40%.

High-Precision Stable Operation

Standard Class C7 ball screws (Class C5 optional) deliver a repeat positioning accuracy of ±0.01mm. Combined with a dual-guide-rail support structure, they ensure stability at an operating speed of 1000mm/s, meeting positioning requirements of mid-range equipment.

High Rigidity and Adaptability

Aluminum alloy profiles undergo T6 heat treatment, offering a maximum horizontal load of 200kg and vertical load of 100kg. With a stroke range of 100-2000mm, they support multiple installation modes (horizontal/side-mounted/vertical), adapting to diverse working conditions.

Cost-Optimized Design

Key components (screws, guide rails) adopt imported core parts, while non-critical components are locally adapted. This reduces costs by 20% compared to fully enclosed modules, making them suitable for bulk industrial equipment matching.

3.Application Fields

Industrial Automation: Material handling in assembly lines, positioning axes of screwdrivers – the ±0.02mm accuracy meets component alignment requirements.

Packaging Machinery: Sealing and cutting positioning in food/daily necessities packaging; the 150kg load capacity easily supports packaging molds.

Warehousing Equipment: Pick-and-place robotic arms for smart shelves – the 2000mm long stroke adapts to multi-layer goods position transfer.

3C Auxiliary Manufacturing: Feeding axes of mobile phone casing polishing equipment – the semi-enclosed design facilitates regular dust cleaning.
