Proper Installation of Linear Guides In this section, we’ll explain in detail how to install THK linear guide in linear type applications. Step 1: Before mounting the linear guides, a highly recommended advice is to clean up all rough edges and contaminate objects. Important: Datum lines of linear guides are normally composed of antirust. So, brush the antirust with a cleanser before positioning. Spraying some low coherence grease can preserve the datum plane. Step 2: Place the linear guide on the base and secure it with the drive screw or other appliances, so it sits properly on the datum line nicely. Important: Don’t forget to examine the adjustment of the screw holes before tightening them. Tightening the screw forcefully can unalign the screw holes, which influences the accuracy and quality due to offset. Step 3: Sequentially fasten the bolts to make the rail more steady. Push the track against the datum line gently to improve the connection between them. Step 4: Through a torque wrench, tighten the bolts from the centre to both edges. Step 5: Repeat similar strides for installing the auxiliary rail and then install the slides on the rail independently. Don’t forget to gather all adornments, like lubricant fitting, grease fitting and seals in this stage. Otherwise, later on, it gets hard to gather the adornments because of less space. Step 6: Locate the table smoothly on the slides on both main and subsidiary rails. Step 7: Tighten the perpendicular thrust screw to settle the table and attach the table screws in the sequence.

• 4-way Equal Load:Each row of balls is placed at a contact angle of 45° so that the rated loads applied to the LM block are uniform in the four directions (radial, reverse radial and lateral directions), enabling the LM Guide to be used in all orientations and in extensive applications
• High Rigidity Type：Since balls are arranged in four rows in a well-balanced manner, a large preload can be applied and the rigidity in four directions can easily be increased
• Self-adjustment Capability：The self-adjustment capability through front-to-front configuration of THK’s unique circular-arc grooves (DF set) enables a mounting error to be absorbed even under a preload, thus to achieve highly accurate, smooth straight motion
• High Durability：Even under a preload or excessive biased load, differential slip of balls does not occur. As a result, smooth motion, high wear resistance, and long-term maintenance of accuracy are achieved
• Rails available:If you need rails,please contact us and send the length
