THK Guida Lineare HSR20LR HSR20 HSR20LR1SS/UU 26x44x90mm GK Cuscinetto Blocco Rotaie Slide per Controllo del Movimento Macchina CNC Stampante 3D

4-way Equal Load: Each row of balls is placed at a contact angle of 45° so that the rated loads applied to the LM block are uniform in the four directions (radial, reverse radial and lateral directions), enabling the LM Guide to be used in all orientations and in extensive applications High Rigidity Type:Since balls are arranged in four rows in a well balanced manner, a large preload can be applied and the rigidity in four directions can easily be increased Self-adjustment Capability:The self-adjustment capability through front-to-front configuration of THK's unique circular-arc grooves (DF set) enables a mounting error to be absorbed even under a preload, thus to achieve highly accurate, smooth straight motion Alta durabilità: anche sotto un preload o un carico biased eccessivo, differenziale slip of balls non occur. Come risultato, smooth motion, high wear resistance, and long term maintenance of accuracy are achieved Stainless Steel Type also Available:A special type which LM block, LM rail and balls are made of stainless steel is also available
