30308M-90KM1
The 30308M-90KM1 is a metric tapered roller bearing assembly featuring a 40 mm tapered bore (1:12 taper) in the ISO 355 standard 303 series. This matched bearing assembly is designed to support combined radial and axial loads with optimized internal geometry for proper load distribution.
Tapered roller bearings are commonly used in automotive wheel hubs, gearboxes, differential assemblies, and industrial machinery where durability under heavy loads and precise shaft positioning are required. The tapered bore allows direct mounting on tapered shafts or sleeves without additional adapter components.
