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 material handling. 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. At first determine the external load that will be placed on the linear bearing, making sure it can handle the forces without compromising performance. Other important selection criteria are the required lifetime, 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 design. Open bearings will be mounted on fully supported shafts for higher bending stiffness while closed linear bearings are used on shafts held only on the ends. The load ratings and the required envelope are the main differences between the Compact (ISO1) and the Standard (ISO3) series.
