Turntable bearings YRT150 China Structure: YRT axial radial bearings, three-row cylindrical rollers slewing bearing. Contains an outer ring, an L-section ring, a shaft locating washer, and cylindrical roller assembly sets. Size: 150x240x40mm Mass: 6.2kg Material: GCr15 Axial/Radial runout: 3μm or 1.5μm (Higher running accuracy available upon request) Lubrication hole: Yes (users can arrange relubrication through the oil holes on the outer ring and L-section ring.) Working temperature: -30â ~ +120â. Preload: All BRS YRT150 bearings have been fitted and fully screw-mounted already, they are radially and axially clearance free and pre-load. YRT150 Rotary Table Bearing Features 1. Because of the 3 row of cylindrical rollers, YRT bearing has high radial and axial loading capacity. 2. Superb rotation accuracy, with axial and radial runout 1.5μm/3μm. 3. YRT150 axial radial bearings are pre-loaded before delivery, can provide high tilting stiffness. 4. With mounting holes on bearing rings, easy to mount and remove.
