33019-90KA1 TRB Metric Assembly 4-8 OD

The 33019-90KA1 is a metric tapered roller bearing assembly featuring a 95mm tapered bore (1:12 taper ratio) in the ISO 355 standard 330 series. This matched assembly configuration provides both inner and outer ring components optimized for proper load distribution in tapered roller bearing applications.

Tapered roller bearings are widely used in industrial gearboxes, wheel hubs, conveyor systems, and machine tool spindles where combined radial and axial loads must be supported. The tapered bore design facilitates mounting on tapered shafts or with adapter sleeves for secure, aligned installation.
