Tapered Roller Bearing 31319 95x200x49.5 mm
Tapered roller bearings are generally of separable design and have tapered cones and cup raceways between which tapered rollers are arranged. Their design makes tapered roller bearings particularly suitable for carrying the combined (radial and axial) load.
Tapered roller bearings can be grouped into metric and inch size series according to dimensional standard differences.
