Linear Guideways

Through careful, clean preparation and a step-by-step approach with a logical procedure, you will be able to achieve a perfect guideway system.

The following installation instructions apply to all types of SCHNEEBERGER linear guideways.

Preparation

To ensure perfect support of the guideway, any remaining burrs or protrusions should be removed using a fine grinding stone.
Before installation, the linear guideways and support surfaces should be cleaned. Through subsequent light lubrication, they will be protected against any subsequent damage.
The marked side of the guideway must not be used as a support surface!

Tip for long guideways or multi-section guideways:
Due to hole tolerances in the guideway, fixing holes on the support surface should be drilled according to the holes in the linear guideway. By using fixing screws with fine shafts, differences in hole spacing can also be adjusted (see Chapter 5).

Step 1

Install Fixed Linear Guideway Pair

The fixed linear guideway pair (1) is pressed against the support using appropriate clamping elements and the fixing screws are tightened (use a torque wrench! For tightening torques, see Chapter 13.5).

Step 2

Check Parallelism

Check parallelism ΔA and ΔP. The measured parallelism must be within the tolerance range of the linear guideway (see Chapter 7.1).

Check parallelism ΔA (horizontal distance) and ΔP (vertical height difference)

Step 3

Install Opposing Fixed Guideway

Install the fixed guideway (2) on the opposite side.

Step 4

Install Guideway and Lubricate

Install guideway (3), only slightly tightening the fixing screws during this process. Perform lubrication (see Chapter 13.8).

Step 5

Insert and Center Cages

Insert and center cages (4). After this, the linear bearing must be preloaded (see next page).

Step 6

Set and Preload Linear Guideway

Set and/or preload the linear guideway to achieve zero clearance (see Chapter 13.5).

Step 7

Apply Preload Sequence

Preload application using adjusting screws should proceed from the center of the guideway outward, following these steps (sequence can be seen from the diagram):

Step 8

Tighten Screws and Install End Pieces

Tighten the fixing screws of guideway (3) and install end pieces.
