Product Overview
Low Profile Roller Linear Guide from JSM is an EBW-series low-assembly-height linear guide manufactured by Zhejiang Jinshanmen Transmission Technology Co., Ltd. (JSM), a China-based manufacturer of linear motion components. Designed for compact automation equipment, precision machinery, and applications with limited installation space, the EBW series uses four rows of recirculating steel balls in a square guide structure to support loads from multiple directions while providing smooth linear movement.
The EBW series is available in sizes 15, 20, 25, 30, and 35, with medium- and heavy-load configurations. Depending on the selected model, different fixing methods, precision grades, preload levels, dust-protection configurations, materials, and surface treatments are available. The low combined height of the guide and slider makes the series suitable for machine structures where vertical installation space is limited.
Technical Specifications
Product Features
Low Assembly Height
The EBW structure reduces the combined height of the guide rail and slider, making it suitable for compact machine structures and motion axes where vertical installation space is limited.
01
Four-Row Ball Raceway
Four rows of steel balls arranged with 45° contact angles support loads in four directions. The recirculating ball structure provides continuous rolling motion along the guide rail.
02
Self-Alignment Capability
The circular raceway geometry provides a self-aligning effect that can absorb a degree of mounting-surface error, helping maintain smooth and stable linear movement during installation.
03
Two Load Classes per Size
Each EBW size is available in an S medium-load configuration and a C heavy-load configuration. The corresponding S and C models are listed with the same basic component dimensions for each size, allowing the load class to be selected according to the machine requirements.

Compact Automation Equipment
For pick-and-place mechanisms, inspection modules, assembly machines, and automated equipment where the overall height of the linear motion system needs to be controlled.
Precision Measurement and Semiconductor Equipment
The EBW format can be integrated into metrology equipment and semiconductor-related machinery where installation space and controlled linear motion are important design considerations.
High-Speed Material Handling
Suitable for transfer units, feed mechanisms, packaging machinery, and repetitive linear movement systems requiring a compact guide arrangement.
Laser Engraving and Compact CNC Equipment
Suitable for compact motion axes used in laser engraving, positioning, light machining, and related equipment, subject to the load, speed, accuracy, and environmental requirements of the machine.

As a manufacturer of both linear guide rails and sliders, JSM offers OEM/ODM options for projects requiring specific configurations. For the Low Profile Roller Linear Guide, customers can select the appropriate EBW size, rail length, number of sliders, fixing method, precision grade, preload, dust-protection configuration, material, and surface treatment according to the machine structure and operating conditions. The EBW series is available in interchangeable and non-interchangeable configurations, allowing the rail and slider arrangement to be selected according to the requirements of the machine assembly. JSM can also work with application factors such as load direction, stroke, installation space, required rigidity, operating speed, and working environment when selecting the suitable guide configuration.
When requesting a quotation, please provide the guide size, rail length, number of sliders, mounting method, load conditions, accuracy requirement, stroke, and working environment. These details allow JSM to identify the appropriate EBW configuration for your equipment instead of treating every project as the same standard application.
About JSM
JSM, officially Zhejiang Jinshanmen Transmission Technology Co., Ltd., is a China-based linear guide manufacturer with almost ten years of experience in linear motion components and systems. The company operates a 20,000 m² self-owned manufacturing facility in Lishui, Zhejiang, equipped with ultra-precision, intelligent multi-sensor 3-axis grinding machines and CNC precision machining centers. JSM has an annual production capacity of 800,000 meters of linear guide rails and manufactures a range of linear motion components, including guide rails, sliders, ball screws, and related products.
JSM provides OEM/ODM services for customers requiring product-specific configurations and application-oriented linear motion solutions. Its products have been supplied to customers in Italy, Brazil, Argentina, Turkey, Australia, and other international markets. For buyers sourcing a Low Profile Roller Linear Guide from a direct manufacturer, JSM combines in-house manufacturing with technical support and product customization, providing a direct source for OEM projects, equipment manufacturers, and long-term industrial supply.
Quality Assurance
JSM applies an ISO 9001 quality management system across its linear motion component manufacturing, with ISO 14001 and ISO 45001 certifications supporting its environmental and occupational health and safety management. Raw materials and finished products are subject to controlled inspection, and each part batch is tested three times to verify accuracy and consistency.
For the EBW series, quality control covers key stages from incoming material inspection and in-process checks to finished-product inspection. JSM's quality team uses equipment such as coordinate measuring machines, guide rail and slider accuracy testing equipment, roughness testers, and hardness testers. Finished products are inspected before storage and undergo a final random inspection before shipment.
Packaging & Shipping
JSM packages linear guide rails and sliders according to export requirements. Sliders are individually bagged and packed in plastic boxes and cartons, while guide rails are individually protected and placed in wooden crates. Customized packaging is also available for different product and shipping requirements. For sea freight, reinforced protection can be added to reduce the risk of deformation during transportation.
FAQ
Q: 1. What sizes are available for the EBW series?
A: The EBW series covers sizes 15, 20, 25, 30, and 35. The appropriate size should be selected according to the applied load, available installation space, stroke, and operating conditions.
Q: 2. What do the S and C codes mean in the EBW model numbers?
A: In the EBW series, S indicates the medium-load configuration, while C indicates the heavy-load configuration.
Q: 3. Can the rail and slider use different fixing directions?
A: Yes. JSM provides top-locking and bottom-locking installation configurations for the EB series, depending on the selected model and structure.
Q: 4. Are stainless steel and surface-treatment options available?
A: Yes. Stainless steel versions are available within the EB series, while JSM also lists hard-chrome and chemical black-chrome treatment options for suitable configurations.
Q: 5. What is the typical delivery time for the EBW series?
A: General delivery is usually 7–15 days after order confirmation, while in-stock items may ship in 1–2 days. Actual timing depends on the selected model, configuration, and order volume.
