Rail layout
Rail spacing and block spacing influence moment loading. End-hole distances and joint positions belong to the installed layout.
Specify rails and matching blocks together, with the details needed to confirm the assembly.

These are specification options within the same family. Actual availability and suitability are confirmed against your request.
A lower assembly height does not guarantee the same mounting pattern as another guide series. Include the installation drawing.
A replacement cage and a complete guide set are different supply requirements. Specify the required assembly level.
A rail-size number alone does not identify a compatible cap, seal or lubrication fitting. Include the accessory reference.
For brand distribution, China-made components and drawing-based parts, origin, specifications and supply terms are confirmed by item.
Rails, blocks and mounting surfaces work as a system. Form factor, preload and accuracy class are considered together with the driven axis.


| Product form | Construction | Selection focus | Connected components |
|---|---|---|---|
| Profile ball guide | Recirculating balls in a profiled rail and block | Block arrangement, preload and load directions | Ball screw, coupling and axis mounting parts |
| Roller guide | Rollers used as the rolling elements | Rigidity requirements and mounting-surface quality | Drive components selected for the same axis duty |
| Miniature guide | Compact rail and carriage geometry | Available envelope, stroke and contamination exposure | Compact screws, couplings and locating parts |
| Flange or square block | Different carriage width and fixing arrangements | Mounting access and carriage-to-table interface | Matching rail, fasteners and table reference surfaces |
Rail spacing and block spacing influence moment loading. End-hole distances and joint positions belong to the installed layout.
Brand, series and interchangeability rules define the valid combination. Similar dimensions alone do not confirm a compatible set.
Grease-port direction, wipers and access for service are considered before adjacent components restrict access.
Guide travel and block layout are coordinated with screw travel, nut location and support positions.
Ball ScrewsRack installation and pinion position share the machine reference system with the guides.
Racks & GearsLocating pins and suitable fasteners maintain the intended relationship between rail, bed and carriage.
Precision Locating FastenersA model, photo, drawing or BOM can start the discussion; brand, quantity and critical interfaces can be clarified by item.
Specified brands, China-made parts and drawing-based components, reviewed against one equipment list.
