Product Overview
A recirculating ball linear guide in the JSM HB series uses four rows of circulating steel balls between a profiled rail and bearing block. Its 45° contact arrangement supports loads in radial, reverse-radial and lateral directions.
The series offers square, low-assembly square and flange blocks for different installation layouts. Buyers can select interchangeable components or matched assemblies according to the machine's accuracy requirements and maintenance arrangements.
Product Features
Rigidity to suit the equipment
Preload can be selected to meet the rigidity requirements of the moving assembly. The choice should also consider operating resistance and installation conditions.
Flexible mounting arrangements
Block configurations accommodate different mounting footprints and bolt access directions. This helps match the guide assembly to the available machine structure.
Protection for the working environment
Standard wipers and bottom seals help limit contaminant entry. Additional scraper and double-wiper arrangements can be specified for conditions involving chips or dust.
Application Scenarios
CNC Machining Centers
For worktable and feed-axis guidance, with selection based on cutting forces, moving mass and load position.
Injection Moulding Equipment
For guided movement of machine assemblies, taking operating loads and cycle frequency into account.
Grinding and EDM Machines
For positioning axes where running accuracy and installation quality affect machining results.
Automation and Transfer Units
For transfer slides and positioning mechanisms, including layouts requiring checks on off-centre loads and overturning moments.
Manufactured by JSM
Zhejiang Jinshanmen Transmission Technology Co., Ltd. manufactures linear motion components at a 20,000 m² factory in China. Our production facilities include precision grinding equipment and CNC machining centers, with an annual output of 800,000 meters of linear guide rails.
JSM's manufacturing and quality management are supported by ISO 9001, ISO 14001 and ISO 45001 management systems. We work with equipment manufacturers, distributors and industrial buyers to review recirculating ball linear guide requirements for specific machine projects.
FAQ
Q. Can this guide directly replace another brand's product?
Matching nominal sizes do not establish compatibility. Provide the existing part number and dimensional drawing so mounting dimensions and assembly requirements can be checked before replacement.
Q. Can the guide carry a vertical axis without an additional holding mechanism?
The guide supports and directs movement; it does not hold the axis in position by itself. A vertical installation requires a separately engineered drive and holding arrangement.
Q. How should matched rails and blocks be handled during installation?
Keep the supplied matching and reference markings identifiable. Follow the assembly instructions rather than mixing components between matched sets.
Q: What should I do if a block must be removed from the rail?
Follow the handling instructions and use a suitable transfer rail where required. Avoid pulling the block off without support or dismantling its circulation components.
Q: Are special inspection reports or order-specific documents available?
List the required documents in your enquiry. Their availability, inspection scope and any related charges should be confirmed before placing the order.
