Product Overview: The LM 40 Linear Motion Bearing
The LM 40 is a high-precision linear motion bearing, a key component in our LM Series of Linear Motion Bearings. With standard dimensions of 40mm bore diameter, 60mm outer diameter, and 80mm length, this bearing is engineered to provide exceptionally smooth and accurate linear movement along a 40mm shaft. It features multiple rows of recirculating balls that run along a hardened steel casing, drastically reducing friction and ensuring consistent performance in demanding applications.
As a leading supplier of industrial and mechanical parts, we ensure our LM 40 linear bearings meet stringent industry standards. They are designed for easy integration into a wide range of machinery, from automated production lines to precision measuring equipment. The cylindrical design allows for simple installation into housings, making it a versatile and cost-effective solution for achieving precise linear guidance.
