Linear Motion Ball Slide Support
Support Units for Round Shaft Linear Motion Systems
Linear motion ball slide supports are used to hold and position round shafts in linear motion assemblies. They work together with linear bearings, slide blocks or moving platforms to build a complete motion system.
Unlike a linear bearing, the support unit does not create movement by itself. Its main job is to keep the shaft fixed and maintain alignment during operation.
For equipment builders, repair projects and OEM buyers, choosing the correct support type is as important as selecting the bearing itself.

Why Is the Support Important?
In many linear systems, the shaft is installed over a relatively long distance.
Without proper support, the shaft can bend slightly under load or become difficult to align during assembly. A support unit helps keep the shaft position stable and makes installation easier.
For longer travel systems, the support arrangement should be considered together with:
Shaft diameter
Travel length
Number of slide units
Load direction
Mounting surface
These factors affect the overall movement more than the support size alone.
Common Support Types
| Type | Description |
|---|---|
| SK Type | End support for round shafts |
| SHF Type | Split shaft support with clamping design |
| Supported Rail Type | Shaft fixed along the full length |
| Custom Support | According to drawing |
The support style is usually selected according to the machine structure and available installation space.
Information Needed for Quotation
For a standard inquiry, the following details are useful:
| Requirement | Example |
|---|---|
| Shaft Diameter | 12 mm |
| Support Type | SK12 / SHF12 |
| Quantity | 50 pcs |
| Material | Standard |
| Drawing | If available |
| Special Requirement | Surface or custom design |
If you already have an existing support, a photo and dimensions are often enough for model checking.
FAQ
1. Is a slide support the same as a linear bearing?
No. The support holds the shaft, while the linear bearing moves along the shaft.
2. How do I select the correct support size?
The support model is normally chosen according to the shaft diameter. The mounting dimensions should also be checked.
3. Can I use one support for a long shaft?
It depends on the shaft length and load. Longer shafts may require additional support points or a supported rail design.
4. What is the difference between SK and SHF supports?
SK supports usually fix the shaft from the end, while SHF supports use a split clamp structure around the shaft.
5. Can supports be supplied according to drawings?
Yes. Custom dimensions and special mounting designs can be discussed for OEM projects.
6. What information should I provide for a quotation?
The shaft diameter, support model, quantity and drawing are usually enough to start.
