JSH20H linear slide (high group)
Specification of JSH Sereis(High Assembly)
The flange part is produced with the threaded installation hole which can use the long screw bolt
Same cross section to JSH-W, engthened the block length, enhance the rated load capacity
Product Feature
• Interchangeability
For the tightly control of production precision, all the size can be maintained at a stable tolerance range.So the interchange type linear guide can keep the same smoothness, preloading and precision when the block arbitrarily assemble on the same type of rail. It is very easy to assemble and repair.
• High Positioning Accuracy
When machine that vectoring by linear guide .the friction coefficient will be 1/50 of sliding friction coefficient.as the friction method of linear guide is rolling friction, the disparity of dynamic friction and static friction will become smaller, when machine runs, there will be no slipping phenomenon and the positioning accuracy can reach very high
• Excellent Lubrication Design
Lubrication design patent, can evenly the lubricating grease injection Patent design of Lubricant oil-way can evenly inject lubricating grease to every loo and obtain the optimal lubrication effect under various installation method, it improves the overall running smoothness and service life to achieve the high precision.high reliability and smooth stability of linear motion requirements
• Four Direction Equal Load Capacity
JSH rail rolling body is to be designed with special pressure angle which make it can bear the same rated load of its radial, anti radial and horizontal direction.
• High Rigidity, High Load
JSH Linear guideway is designed with four columns arc grooves which increase the contact area.compare with two cloumns groove design.it has been greatly improve on the loading capacity, contact stiffness and system rigidity.
• High Precision
JSH linear guideway is produced by high precision special plane which can polyhedrally grind at the same time, detected by laser and other advanced process.all of these guarantee the manufacturing precision of TRH linear guideway.
• Smoothness, Low Noise
The returning device of JSH linear guide adopt a simple and lubricant ball recirculation design with shock resistant circulative accessory –strengthening synthetic resin.the smoothness of the movement is good which achieves a smooth and noiseless linear motion.
• Compact Structure
The section and rigidity of JSH linear guideway attain the most optimal design which is with a small section but high rigidity,thus achieve the purpose of miniaturization of machine tool.
• Easy Installation
Low requirements of installation guide for JSH users, it is easy for installation and debugging
• With automatic self-aligning capability
Arc groove design of the front combination makes the linear guideway has the ability to automatically adjust the center, even if to give preloading it can absorb installation error, and maintains a high precision,smooth and stable linear motion.
Accuracy for Choose
Five accuracy grades for choose：Normal/High/Precision/Senior Precision/Top Precision.
The accuracy of JSH series products are mainly reflected on three aspects: accuracy of running parallelism, accuracy of assembly size, accuracy of the position error of hight and width in pairs( when several blocks used on one rail or several rails install on one plane, the position error of height and width in pairs is prescriptive)
For details please refer to the specification table
Accuracy Specification
Geometric tolerance and accuracy of JSH type show as table 1 in page AOS and table 2 in page A06, the accuracy of each type is separated into :Normal,High,Precision,Senior Precision,Top Precision.
Size Accuracy Inspection of JSH Linear Guide (Table 1)
Installation Accuracy
The allowable error of linear guide installation
The block of JSH series has the ability to automatically adjust the center, even if the installation face has a little error, it can still have the smoothly linear motion according different pre-load (such as to meet the following allowable error range). This is the special advantages of JSH series linear guide products
