HGL15CA Linear Guide Block Carriage Slider Rail Guideway Bearings Motion Control for CNC Machine Tools 3D Printer Automation Industry

A linear guideway allows a type of linear motion that utilizes rolling elements such as balls or rollers. By using recirculating rolling elements between the rail and the block, a linear guideway can achieve high precision linear motion. Compared to a traditional slide, the coeficient of friction for a linear quideway is only 1/50. Because of the restraint effect between the rails and the blocks, linear guideways can take up loads in both the up/down and the left/right directions. With these features, linear guideways can greatly enhance moving accuracy, especially, when accompanied with precise ball screws. 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 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 . 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 , 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.
