KOYO bearings : M272749/10 Type: Inch series tapered roller bearings, TS type Bore diameter: 479.425 mm Outer diameter: 679.450 mm Depth: 128.588 mm Dynamic load rating: 5550,000 N Static load rating: 2470,000 N Radial reference speed: 726 r/min Axial reference speed: 413 r/min Bearing weight: 137.02 KGS Country of origin: Made In JAPAN Contact: sales@hzskf.cn skype: lovejoanna8 www.industrybearing.com KOYO inch size bearing M272749/10 is TS type tapered roller bearings with medium contact angle. It can accept radial loads or axial loads in one direction and combined radial and axial loads. Since the outer ring is separable from the inner ring assembly, the inner ring assembly can be installed on the shaft and the outer ring in the housing individually. KOYO JTEKT has a strong reputation of inch-series tapered roller bearings in such areas as the size, weight and environmental friendliness of these KOYO bearings.

JTEKT has employed vacuum-degassed bearing steel as JTEKT standard bearing material. It has a significant effect on bearing life extension which was verified through studies as JTEKT laboratory.
