Taper Roller Bearing Single Row 31305, 25mm Bore
Cartridge Tapered Roller Bearing
This type of bearings are designed to accommodate both radial and axial loads.
Separable design, i.e. the cone, consisting of the inner ring with roller and cage assembly, can be mounted separately from the cup (outer ring).
Strong operation reliability and low sensitivity to misalignment
Taper roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at a common point on the bearing axis. Their design makes taper roller bearings particularly suitable for the accommodation of combined (radial and axial) loads.
