description Provided is a cylindrical roller bearing for a turbo refrigerator, in which a silicon-containing DLC coating film is formed on the surface of an inner ring raceway and the concentration of silicon at the outermost surface of the DLC coating film is 1-17 atom %. By using this silicon-containing DLC coating film, it is possible to prevent, over a long period of time, damage caused by skidding. L'invention concerne un roulement à rouleaux cylindrique pour un turbo-réfrigérateur, dans lequel un film de revêtement de DLC contenant du silicium est formé sur la surface d'un chemin de roulement de bague intérieure et la concentration de silicium au niveau de la surface la plus extérieure du film de revêtement de DLC est de 1 à 17 % atomique. En utilisant ce film de revêtement de DLC contenant du silicium, il est possible d'empêcher, sur une longue période de temps, les dommages causés par le dérapage.  内輪軌道面に、珪素を含むDLC皮膜が形成されており、かつ、前記DLC皮膜における最表面の珪素濃度が1~17原子%であるターボ冷凍機用円筒ころ軸受。この含珪素DLC皮膜により、スキッディングによる損傷を長期間防止することができる。
