Product Overview

An Anti-Corrosion Linear Guide from JSM provides linear guidance for equipment operating in humid conditions or environments where exposed metal components face corrosion risks. As a manufacturer of linear guides and sliders, Zhejiang Jinshanmen Transmission Technology Co., Ltd. offers stainless steel and surface-treated configurations for review against your machine design and operating conditions.

Selection considers both mechanical requirements and environmental exposure. Send your installation drawing, load information and details of moisture or process chemicals to help identify a suitable configuration.

Material and Surface Treatment Options

JSM's catalogue includes coated rail and block configurations alongside stainless steel alternatives. The following codes identify material or treatment options within the applicable ordering systems.

Code	Catalogue Configuration	Ordering Consideration
S	Stainless steel	Confirm the material specification and component coverage for the selected assembly.
HC	Standard steel with hard chrome plating	Confirm availability for the required rail, block and accuracy specification.
NC	Standard steel with chemical black chrome treatment	Confirm treatment coverage and suitability for the operating environment.

These options are not interchangeable performance grades. The rail, block, rolling elements, screws and lubrication fittings should be reviewed as an assembly. Seals and other non-metal components also require compatibility checks where process liquids are present.

Configuration and Selection

An Anti-Corrosion Linear Guide should be specified around the exposure conditions as well as the required size. JSM's catalogue identifies stainless steel availability across selected HB, EB and MB models; the final configuration must be confirmed for the chosen series.

Please provide:

Required rail length, block quantity and mounting dimensions.

Moving load, load position, travel speed and duty cycle.

Accuracy, preload and interchangeability requirements.

Whether exposure involves humidity, condensation, splashing or direct liquid contact.

Names, concentrations and temperatures of any cleaning or process chemicals.

Corrosion-resistant materials do not remove the need for lubrication, drainage or appropriate machine guarding. These provisions should be included in the installation design.

Applications of Anti-Corrosion Linear Guide

Automation in Humid Production Areas
For transfer slides and positioning assemblies where condensation or airborne moisture can reach the guidance system.

Testing and Laboratory Equipment
For adjustment stages and moving fixtures where the expected atmosphere and any liquid exposure can be defined before selection.

Process Equipment Positioning Units
For guided mechanisms near processing operations. Suitability depends on the specific substances present and how frequently they contact the assembly.

Manufactured by JSM

JSM manufactures precision linear motion components in a 20,000 m² factory equipped with precision grinding machines and CNC machining centres. Our annual linear guide rail output is approximately 800,000 metres, supported by an ISO 9001 quality management system.

For OEM equipment projects, work directly with our manufacturing team to review the guide series, mounting arrangement and material or treatment specification. Include the agreed configuration in your purchasing documents to support consistent repeat orders.

FAQ

Q: Can I replace an existing guide using the same nominal size?

A: Nominal size alone does not confirm compatibility. Provide the existing model, assembly height, mounting hole pattern and rail dimensions. Replacement suitability also depends on the accuracy and interchangeability requirements.

Q: Can salt spray test results predict service life in my machine?

A: Salt spray testing provides comparative evidence under defined laboratory conditions. It does not directly establish service life in an operating machine. Request the applicable report and check its specimen configuration, test duration and acceptance criteria against your purchasing requirements.

Q: Can I shorten a coated rail after delivery?

A: Confirm this before ordering. Cutting can expose untreated material at the rail end and may require additional protection. Where possible, specify the finished rail length during the quotation stage.
