Accuracy for Choose
Five accuracy grades for choose: Normal/High/Precision/Senior Precision/Top Precision.
The accuracy of TRHG series products are mainly reflected on three aspects: accuracy of running parallelism, accuracy of assembly size, accuracy of the position error of height 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)
Accuracy Specification
Geometric tolerance and accuracy of TRHG type show as table 1in page A05 and table 2 in page A06, the accuracy of each type is separated into: Normal, High, Precision, Senior, Precision .Toy Precision.
Installation Accuracy
The allowable error of linear guide installation
The block of TRHG 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 TRH series linear guide products.
Structure of Connective Datum of Linear Guide
When install two rails on one surface ,both of the rails and blocks should have the locating surface if the load type is impact load and requirement of the precision is high. as that shows in picture 1
Height and Chamfering of Installation Platform
First, When install the block and rail to lathe or work table, it should undercut a groove to avoid the rail interfere with the reference surface (table-10)
Second, know clearly about the reference-side when installation.
Installation and Adjustment of Linear Guide
1、Installation and Use
Please Handling the products gently to avoid to influence of the precision of the linear guide. The block is not allowed to detach the rail or push back to the rail when it is over stroke. If the block need to dismantle from the rail because of the difficulty assembly, you can order the fake rail from us. (fake rail is a Auxiliary tools which has a smaller size than the guide rail. When dismantle the block, firstly joint the end of fake rail and guide rail, then push the block from the guide rail to fake rail. When the guide rail is assembly, push the block from the fake rail back to the guide rail, pay attention of the reference direction when do these steps)
2、Install Caution
When install the products distinguish the reference guide rail and non-reference guide rail clearly (the reference guide rail has the reference mark and the block has a reference-side polished surface)

3、Installation Step of Guideway
Check the mounting surface.
Set the reference- side of guideway opposite to the reference-side of installing step.
Check the position of the bolt hole, to determine the correct position.
Preloading to fix the bolt, make the reference-side of guideway closely connect to the side of installing step.
Finally screw down the bolt.
Tightened the fastening screws of block in turn.

4、Installation methods of reference linear rail (two ways for choose as following)
To use a U-type grip holder to clamp the reference surface of rail and reference side surface of installation step. Then use the fixed bolt to tighten the rail（tapping hole is suggested),it should fix in turn from one end to the other end.
When there is not installation step, first fixed one end of the rail ,then according to the following picture ,lean the gauge on the reference surface of the rail, adjust the linear accurancy from the guage then fix the rail in turn.
5、Linstallation Methods of Non-reference Linear Guide
As showed in the picture .Fix the lron absorption meter onto the block. Read the parallelism and then fixed the non-reference rail in turn.

6、Distinction of the Lengthened Linear Guide Rail
When rail that need to joint to be lengthened, we will write the same capital on one set rail ,and the continuous Arabic numerals to indicate the joint sequence, the joint end mark the same arabic number (as showed in picture)
7、Pairing the use of docking rails
1, rail mounting base should have a base and side datum
2, the docking part in accordance with the docking mark stitching docking connector should be staggered to install
3, rail installation side of the base surface should be installed when the pressure to ensure that the side surface and ensure that the surface coincide.(Specific installation diagram shown in Figure 1. Figure 2)

8、When tightening the bolt, shoud use a constant torque wrench and install as the recommend torque value as the following table
