Product Overview
Flat linear guide assemblies in the JSM EB series provide guided motion for machinery with limited vertical installation space. Each assembly combines a profiled rail with recirculating ball blocks for use in compact moving tables, feed mechanisms, and positioning units.
The range includes EBH square blocks with a narrower footprint and EBW flanged blocks with wider mounting-hole spacing. These configurations accommodate different moving-plate layouts and available lateral clearance.
Technical Specifications
Product Features
Low mounting profile
The reduced assembly height helps integrate the guide beneath moving platforms and inside compact machine frames.
01
Four-direction load capacity
Four rows of balls with 45-degree contact angles provide equal rated load capacity in the radial, reverse-radial, and lateral directions.
02
Selectable preload
Preload options allow guide rigidity to be matched to the operating requirements. The appropriate option depends on the selected accuracy grade and assembly configuration.
03
Ball retainers
Retainers help prevent ball loss when the block is removed from the rail, making handling during installation and maintenance more convenient.
04
Application Scenarios
Compact Automation Equipment
For pick-and-place slides, assembly fixtures, and inspection modules with restricted installation space. The blocks support the moving tooling or workpiece platform along its travel.
Packaging and Transfer Mechanisms
For feed slides, product-transfer units, and positioning stations in packaging machinery. The guide supports repeated linear movement between loading, processing, and discharge positions.
Measurement and Semiconductor Equipment
For guided stages in measuring instruments and semiconductor-related machinery. Applications with specific cleanliness or lubricant requirements require a separately confirmed configuration.
Laser Engraving Equipment
For positioning axes in compact laser engraving machines, including moving worktables and guided head assemblies. The low-profile arrangement helps fit the motion components within the machine enclosure.
Zhejiang Jinshanmen Transmission Technology Co., Ltd. (JSM) manufactures linear motion components in its own 20,000 m² factory. Precision grinding equipment and CNC machining centers support an annual linear guide rail output of approximately 800,000 meters.
OEM support includes reviewing rail length, block arrangement, and special machining requirements against customer drawings. Proposed changes are assessed for the selected model before the order specification is finalized.
JSM conducts raw-material and product inspections under its ISO 9001 quality management system. The company also holds ISO 14001 and ISO 45001 certifications for environmental and occupational health and safety management.
Customers with specific acceptance criteria should identify the required dimensional checks, accuracy characteristics, and inspection records before ordering. The inspection scope and available documentation can then be confirmed for the project.
