Flanged Linear Bearings LM
For achieving maximum positioning accuracy in 3D printers and CNC machines, LM flanged linear bearings are utilized. The LM series bearings can be installed in assemblies and mechanisms on planes that are perpendicular to the direction of motion, as well as in devices where the shaft moves relative to the bearing.

Description
Линейные подшипники выступают в роли направляющих типа качения. Одним из основных преимуществ которых является малая сила сопротивления движения. Это помогает как быстро развивать высокую скорость перемещения, так и плавно двигаться на маленьких скоростях.
При использовании в конструкции 3д принтера или ЧПУ станка данный тип подшипников способствует уменьшению износа валов и нагрузки на ременные или винтовые пары.

LM bearings consist of an outer sleeve containing a plastic separator, balls, and sealing rings at both ends. The steel casing of the bearing and the plastic separator ensure durable and reliable operation. Flanged bearings are designed to protect against dirt ingress from both sides. The LM linear bearings allow for convenient installation onto mechanisms thanks to the presence of the flange.
Main features:
- Durable Design: Made with high-quality materials for longevity.
- Effective Sealing: Dual seals prevent contamination from dust and debris.
- Flanged Configuration: Simplifies mounting and enhances compatibility with various mechanisms.
- Precision Performance: Designed to provide high accuracy in linear motion applications.
- Versatile Installation: Suitable for a range of applications, including 3D printers and CNC machines.
LM Flanged Linear Bearing scheme
LM flanged bearings are designed for direct installation into CNC machine mechanisms. This design significantly reduces the overall dimensions of the working assembly while greatly increasing its rigidity on the guiding shaft. We also offer modifications of flanged linear bearings with an extended body.
The casing is made from bearing steel, while the cage is constructed from plastic. The bearings are equipped with double-sided seals made of vulcanized rubber O-rings.
Specifications
- Maximum Speed: 5 m/s
- Operating Temperature Range: -20°C to 80°C
- Friction Coefficient: 0.001 – 0.005
- Mounting Hole Tolerance: H7
Application
LM linear bearings are used for linear movement along cylindrical guides. The balls located within the bearings roll between the guide and the raceway in the bearing, providing low resistance to translational movement. As they move, the balls enter return channels, allowing them to pass without contacting the guide and creating no hindrance to movement. This design ensures high wear resistance for both the guide and the bearing, making LM flanged linear bearings suitable for the production of high-precision equipment and CNC devices.
Pay attention: Rolling linear bearings are not recommended for rotational movement
