Product Overview

Extra Heavy Duty Linear Guide in the HBH-HA series is designed for machine axes requiring high load capacity, rigidity, and stable linear movement under demanding operating conditions. It adopts a square carriage structure with four-row ball circulation and arc-shaped raceways arranged at a 45° contact angle, allowing the carriage to support loads from multiple directions.

Manufactured by Zhejiang Jinshanmen Transmission Technology Co., Ltd. (JSM TRANSMISSION), this series is produced for industrial equipment manufacturers and distributors requiring reliable linear motion components. JSM specializes in the development and manufacturing of linear guide rails, carriages, ball screws, and related transmission components, supported by its own production facility and OEM/ODM capabilities.

The HBH-HA series is available in sizes from HBH20HA to HBH65HA, allowing customers to select suitable configurations according to load requirements, installation space, and machine design.

Technical Specifications

Product Features

Four-Direction Load Support

The HBH-HA structure supports loads from vertical and lateral directions, making it suitable for machine axes where the guide system is exposed to combined loading conditions.

Extended Carriage Design for Higher Load Capacity

The HA version features an extended carriage design that provides higher dynamic and static load ratings for heavy-duty applications. The longer carriage structure helps improve load distribution while maintaining stable linear motion.

Selectable Preload for Rigidity Requirements

Z0, ZA, and ZB preload grades are available for non-interchangeable HB assemblies, allowing rigidity to be matched to accuracy grade and operating condition rather than fixed at a single setting.

Applications

The HBH-HA series is commonly selected for industrial equipment requiring high load support and positioning stability, including

CNC machining centers and heavy milling machines

Grinding, boring, and precision measuring equipment

Large-format automation and gantry-type equipment

Material handling systems and transfer platforms

Frequently Asked Questions

Q: 1. Can I purchase rails or blocks separately, or must they be ordered as a set?

A: Separate purchase is available for supported JSM interchangeable configurations. Specify the complete product code, accuracy grade and preload when ordering. Non-interchangeable HB assemblies should be ordered as matched rail-and-block sets.

Q: 2. Can I use this guide to replace an existing guide from another brand?

A: Replacement requires a comparison of the installation dimensions and performance specifications. A matching nominal size does not confirm compatibility. When requesting a review, clarify whether you intend to replace the complete assembly or retain the existing rail and replace only the block. Cross-brand rail-and-block compatibility should not be assumed.

Q: 3. What information is needed for model selection?

A: Please provide the working load, load direction, stroke length, operating speed, required accuracy grade, number of blocks, and installation conditions. JSM can review these parameters and assist with product selection.

Q: 4. Can this guide replace another brand's product directly?

A: Compatibility should be checked against technical drawings. A similar size designation alone does not confirm matching assembly height, mounting-hole positions, accuracy grade, or preload requirements. JSM can review the specifications before replacement.

Q: 5. Does JSM support OEM and ODM orders?

A: Yes. JSM provides OEM and ODM services for industrial customers. Logo requirements, specifications, and order details can be discussed according to project requirements.
