Linear bearings (also called ball bushings or shaft guides) are composed by linear bearing, block and shaft and are cost-effective and widely used in a variety of applications as linear guide systems. The guiding principle consists of three elements: linear ball bearings, bearing housings and precision shafts. The wide range of diameters combined with the different types of bearings, housings and shafts make it easy to use and flexible to design in. Shaft guides provide low-friction guidance at unlimited travels and high tolerance to misalignments. 
Ewellix is one of the leading manufacturers of linear bearing, block and shaft and and linear bearings manufacturers due to its extensive experience and professionalism in the industry.

Frequently asked questions

Linear bearings are mechanical components designed to allow linear movement along a machine axis. These devices are essential in various industrial applications, such as machine tools, robotics and conveyors. Linear bearings reduce friction and allow smooth, precise movement, improving system efficiency and accuracy. They are made of high-quality materials and designed to withstand heavy loads and resist wear. Linear bearings also offer high rigidity and stability, providing longer life. Choosing the right linear bearings for your application's specific needs can improve overall system performance and lower maintenance costs.

Choosing the right linear bearing is critical to ensuring smooth and precise movement in your mechanical system. Carefully consider a few crucial factors when selecting a linear bearing. It is critical to first determine the required load that will be placed on the linear bearing, making sure it can handle the forces without compromising performance. Other elements of design to consider will be life required in distance or number of years of service, speed of movement and the environment in which the bearing will be used. Finally, be sure to also evaluate dimensions and compatibility with other system components. Choosing the right linear bearing for your needs will improve the efficiency and reliability of your system.

There are different types of linear bearings available on the market, each with specific characteristics and advantages. Linear ball bearings are designed for fast, precise movement. Linear bearings are available in open and closed configurations. Open bearings will be mounted on fully supported shafts for higher bending stiffness while closed linear bearings ride on shafts held only on the ends. It is essential to consider the load, speed, precision and operating environment in order to choose the right type of linear bearing for your specific needs.
