Linear ball bearings are a type of bearing that support the load of a carriage during single-axis linear movement and provide a low friction sliding surface for the guide rail. The bearings support this carriage in this motion. The linear ball bearings reduce the friction during the movement along the axis. Linear ball bearings allow the carriage to move with excellent precision, better mounting, and smooth and even motion. Linear ball bearings are a critical component of a linear guide assembly.

Advantages of Linear Ball Bearings
Linear ball bearings offer a significant advantage over other options for linear motion systems. Linear ball bearings contribute to increased efficiency and reliability, with a decrease in downtime for linear motion systems in various industries. Some of the key benefits of using linear ball bearings include:
High Precision
Using linear ball bearings will give your linear guide system a high degree of precision and accuracy.
Low Noise
Linear ball bearings are able to bear large loads with less noise than other options, which is important in many industries.
Smooth Motion
Smooth motion of the linear guide system is important for many industries and will allow the application a longer lifespan.
Reduced Friction
Friction during linear motion can cause a variety of issues within the application. Linear ball bearings work to reduce that friction, allowing for smoother movement.
Minimal Wear
While wear is inevitable in many industrial applications, using linear ball bearings will reduce the wear on the system, allowing the system to operate for much longer without replacement.
Low Maintenance
Linear ball bearings are not maintenance-free and do require scheduled inspections and regular lubrication, but overall are considered a low-maintenance application in most industrial applications, which will reduce potential downtime.
Lower Operating Costs
Although linear ball bearings require an initial investment, due to their advantages of increased longevity, lower maintenance needs, and decreased downtime, they are the more cost-effective solution in the long run.
Types of Linear Ball Bearings
There are several different types of linear ball bearings with slight differences in construction, materials, and advantages in various applications. When choosing linear ball bearings, it is important to consider the application and which features are most important.
Non-Recirculating Linear Ball Bearings
Non-recirculating bearings have balls or rollers that are contained in a housing and directly support a load. As the bearing moves, the rolling elements rotate on their own axis, but do not travel within the housing. The length of the bearing limits the load, but because the rolling elements only rotate, they provide extremely smooth motion with a high degree of accuracy. High precision applications often require non-recirculating linear ball bearings.
Linear Recirculating Ball Bearings
Recirculating ball bearings move in circles continuously through a path within the bearing. This design allows for the bearing to travel any distance, regardless of the length of the bearing, and can support large loads. However, their accuracy is less than non-recirculating bearings and the maximum speed is limited. Recirculating bearings are often considered the “default” ball bearing for linear guide systems, as they will work in a variety of applications.
Linear Plain Bearings
Plain bearings do not operate according to the traditional rolling system but instead by sliding. Plain bearings are compact, lightweight, quiet, and less costly than rolling and recirculating bearings. Although they are not ball bearings, they do have their place in linear motion systems.
Linear Roller Bearings
Linear roller bearings come in standard sizes that are predetermined and are less able to be customized for a specific application. Roller bearings are not considered as accurate or smooth as other linear bearings.
》They can get quite noisy at times.
》They are incapable of handling heavy loads.
》Shocks may cause damage.
》Linear ball bearings are highly-priced.
