LM Block Used in the Structural Beam Model JR Gets an Update for Convenient Top and Side Lubrication

THK CO., LTD. (Location: Minato, Tokyo; President: Takashi Teramachi; hereinafter referred to as “THK”) has updated the LM block used for certain sizes of the Structural Beam Model JR.

he Model JR is an LM Guide that leverages high-precision linear motion technology, adapting a structural beam designed to provide high flexural rigidity to serve as the LM rail. It is widely used as a linear motion guide in automated warehouses, car elevators, and stage systems. Model JR25 and JR35 LM blocks have recently been updated to enable lubrication from their top and side surfaces. This innovation makes maintenance more convenient without changing the product's mounting dimensions. The specifications of the LM rail remain unchanged. At THK, we will continue to use the technology and know-how we have cultivated through our linear motion guides to develop and provide products that boost our customers’ productivity and machine performance.
