12 best linear guide rail
Linear guide rails are critical components in various industrial and scientific applications, primarily focused on linear motion control and precision. They play a fundamental role in guiding and supporting the movement of machinery, tools, and equipment along a straight path, ensuring accuracy, stability, and smooth motion.These components are essential in industries ranging from manufacturing and automation to robotics and scientific instrumentation.
Key features and aspects of linear guide rails include:
Linear Motion Guides: Linear guide rails are often paired with linear motion guides, which are components designed to move along the rail. These guides come in various forms, such as linear bearings, linear slides, or linear carriages. They enable controlled, frictionless motion along the rail.
Types of Linear Guide Rails: There are several types of linear guide rails available, each with its own set of characteristics and advantages. Common types include:
Ball Bearing Linear Guide Rails: These guides use ball bearings to reduce friction and provide precise linear motion. They are widely used in many industrial applications due to their high load capacity and smooth operation.
Roller Bearing Linear Guide Rails: Roller bearings replace ball bearings in this type of guide rail. They offer higher load capacities and improved rigidity, making them suitable for heavy-duty applications.
Profiled Rail Linear Guide Rails: These rails have specially designed profiles that provide enhanced rigidity and accuracy. They are often used in applications requiring high precision.
Crossed Roller Linear Guide Rails: Crossed roller bearings are used to achieve exceptional accuracy and rigidity, making them ideal for applications like CNC machines and measurement equipment.
Materials and Construction: Linear guide rails are typically made from materials like stainless steel, hardened steel, or aluminum to ensure durability and resistance to wear and corrosion. They are precision machined to maintain strict tolerances for smooth movement.
Applications: Linear guide rails are used in various industrial and scientific applications, including:
- CNC machining and milling machines
- Industrial automation and robotics
- Semiconductor manufacturing equipment
- Medical devices and diagnostic equipment
- Optical and scientific instruments
- 3D printers and additive manufacturing systems
- Packaging machinery
Benefits: The use of linear guide rails offers several benefits, such as increased accuracy, repeatability, and load-bearing capacity. They also help reduce friction and wear, resulting in longer-lasting machinery and improved overall performance.
In summary, linear guide rails are essential components in industries that require precise linear motion control. They come in various types and materials to suit different applications and are critical for ensuring the smooth and accurate movement of machinery and equipment.

User questions & answers
| Question: | Do you have a technical data sheet for this item? (e.g. stiffness, load capacity, etc) I am planning on using a motor with a capacity of 3.5 HP |
| Answer: | have not been able to find any data specific to this rail I can tell you I am using them on a 1000mm x600mm cnc bolted directly to the side frame of the machine 2 rails per side and I have not been able to detect any deflection in the rails which are carrying 40 odd pounds of gantry , motors ,spindle and such the bearings do have some slop but this can be tweaked out with the 2 adj screws on each bearing to end up with a very near zero deflection |
| Question: | Is it possible to connect these end to end |
| Answer: | In a perfect world absolutely. Satisfactory results are dependent on the flatness of the mounting bed and your ability to machine/chamfer/square the rails (I would recommend doweling the rail ends if you have access to a CNC or lathe) |
| Question: | Can this be used for 3d delta printers as the vertical sliders |
| Answer: | It appears to me that delta printers use a different styles slide. My first impression would be the answer is no. These components soul have to be placed side by side to see off modifications could be made to accept what your suggesting. I am not familiar with delta printers. I did however do a little research. So to offer these as a replacement should be investigated thoroughly... Good luck, Len |
| Question: | What does SBR refer to and which is best for a plasma cnc table |
| Answer: | Short base rail. I would see if they have larger one.. these would work if it’s a small cnc like a 2’x4’. |

User questions & answers
| Question: | Can these be used for an x - y router where there would be significant side loading to the rails (a gantry type design |
| Answer: | These are nice guides, but I would not use them for a router. I use them to move a splash guard up and down, but I would not rely on them for anything precise or heavy duty. The carriage has about a 25° rotation to both sides of the rail so a side load would be difficult. |

| Question: | Can I order a shorter length |
| Answer: | Yes |
| Question: | Why are the grease fittings and hole covers so hard to find? Could you start selling them here |
| Answer: | Just oil the rails, maybe once a year. There is no need to get fancy with grease pumps. |
| Question: | Is there any force or weight capacity listed for these? my gantry will weigh roughly 175 pounds (for a 5x10 cnc plasma |
| Answer: | Considering the weights is divided between 4 blocks there shouldn’t be a problem supporting your gantry. That said, you didn’t mention the type of cnc you are planning on. Will it be routing, milling, or just plasma. Some have higher axial loads that could exceed these capabilities. |
| Question: | The tech details states that these rails are 5mm wide but the picture shows 2cm and the text description says 15mm? What is the correct rail width |
| Answer: | Yes, 15mm wide and whatever length you choose Ken |

CNCCANEN
Product description
Package:
2 X SBR12-1000mm FULLY SUPPORTED LINEAR RAIL
4 X SBR12UU Motion Router Solide Block Bearing We can customize the lengh whatever you want, pls contact us before buying.
Linear bearing is a low-cost production of linear motion system for unlimited travel in conjunction with the cylinder axis. Because of point contact between ball and straight axis, so the load is small. The ball is spinning with the smallest friction, it can run a high precision and smooth motion. Flange linear bearings can be divided into: round flange type, oval flange, guide wheel flange, guide the oval flange type, plus long round flange type.
This is the sliding unit with the aluminium case, shafts and aluminium rail for preventing deflexion. This is the complete sliding unit systems and can be clamped simply tightening by bolt with high accuracy. The support rail unit provides maximum rigidity and stiffness to the shaft throughout the whole stroke, and ensure the performance of the unit.
The shaft is case hardened. If you use normal steel shafts, the bearings will cut them up in no time. So make sure what you buy is case hardened!
