12 best linear roller bearings
Linear roller bearings, also known as cylindrical roller bearings, are a type of bearing used in various industrial and mechanical applications to provide linear motion with reduced friction.These bearings are designed to support high radial loads while allowing for smooth and precise linear movement along a linear rail or guide.
Here are some key characteristics and features of linear roller bearings:
Rolling Elements: Linear roller bearings consist of cylindrical rollers instead of balls, which distribute the load more evenly and offer higher load-carrying capacity compared to linear ball bearings.
High Load Capacity: Linear roller bearings are capable of handling significant radial loads, making them suitable for applications with heavy loads and high forces.
Low Friction: The rolling motion of cylindrical rollers reduces friction, resulting in smoother and more efficient linear motion.
Precision: These bearings are known for their high precision and accuracy, making them suitable for applications where precise positioning is critical, such as CNC machines, automation systems, and industrial robots.
Variety of Types: Linear roller bearings come in various designs, including open or closed configurations, single or double-row arrangements, and different cage materials, allowing for customization based on specific application requirements.
Maintenance: Linear roller bearings generally require minimal maintenance due to their design and use of rolling elements. Proper lubrication is essential to ensure their long-term performance.
Diverse Applications: They are used in a wide range of industries, including manufacturing, aerospace, automotive, medical equipment, and more, wherever linear motion with high load capacity and precision is required.
Linear Motion Systems: Linear roller bearings are often integrated into linear motion systems, which may include linear rails or guides and other components to create complete linear motion solutions.
Compatibility: These bearings can be used with various types of linear guides and rails, such as profiled rails, round rails, and flat guides, depending on the specific application requirements.
In summary, linear roller bearings are essential components in many industrial and scientific applications, offering high load capacity, precision, and efficiency in providing linear motion. They play a crucial role in the field of power transmission and are widely used in a variety of industries to facilitate smooth and precise linear movement.

User questions & answers
| Question: | How much weight can it support? can i use this to build a truck bed slide |
| Answer: | at this time I have only used it between 250 pounds to 275 |
| Question: | can the rails be put end to end for twice the length if you don't mind a little bump will roller go from one rail to the next at all if lined up good |
| Answer: | If you don't mind a bump they can be aligned as you suggest. But for CNC use this bump can be enough to throw off the linear measurement. I think you can disconnect the round runner from the rail and stagger the joint so they will act like one long rail however there will still be a bump. |
| Question: | Would these work as an upper rail, if supported from the bottom |
| Answer: | Depends on the amount of weight you are trying to suspend. The rails are firmly seated in the guides- but if you don’t have the right number of guides, you will get sag in the rail, and you load will bind |
| Question: | What part can I use to stop the blocks from sliding off the end of the rail |
| Answer: | I went to my local hardware store and bought stops. Some are in two halves others are made to slip over the bar and tighten. They come in various sizes. Look in the specialty nuts, bolts, and fasteners section. |

User questions & answers
| Question: | what is the maximum distance traveled on X, Y and Z axis respectively |
| Answer: | X, Y: 13mm Z: 10mm |
| Question: | What is the female thread in the holes |
| Answer: | The threads on the top plate are metric M3 |
| Question: | is there any screw holes at the bottom surface(if we want to mount this actuator on a part |
| Answer: | Yes. One side has 9 blind, tapped M3 holes, 16mm on center. The other side has four untapped through-drilled M3 holes 32 mm on center with counterbores on the opposite side for nuts or cap head screws. That side of the unit also has four blind tapped holes, two on each the plate edges without the actuator and lock. These appear to be M2, but I couldn't confirm that. |
| Question: | Can this be mounted on a breadboard and hold a part at the same time? If so, how |
| Answer: | There are 4 M3 tapped holes (40mm square) on top for mounting your part to the stage. There are also 4 holes in the bottom (also a 40mm square) where you can use M3 socket head cap screws to mount the stage to tapped holes in your breadboard. You have to adjust the bottom stage to its limits to access the mounting holes. Hope this helps. |
