Noise monitoring: Vibration meters monitor the vibration conditions during operation to obtain noise data.
Raw material control: Steel and parts are sourced from ISO 14001-certified suppliers, ensuring product stability while promoting sustainable development.
Features & Benefits
When your application calls for precision axial load-carrying capacity, there’s nothing better than thrust bearings. A thrust bearing is a rotary bearing designed to support axial loads on rotating shafts, which permits smooth rotation under high thrust loads at low and medium speeds. The axial load from the rotating shaft is absorbed into the stationary housings or mounts within which the thrust bearing turns.
