SW 30208 Tapered Roller Bearing | 40x80x19.75mm | High Load Capacity & Durability

The SW 30208 Tapered Roller Bearing is engineered to meet the rigorous demands of heavy industrial and automotive applications. Designed to handle simultaneously acting radial and thrust (axial) loads, this single-row tapered configuration ensures precise shaft guidance and outstanding stability under extreme operational conditions. Manufactured from high-purity, case-carburized bearing steel, the 30208 features geometrically optimized raceway profiles that minimize stress concentrations and deliver uniform load distribution. Its separable design allows the cone (inner ring and rollers) and the cup (outer ring) to be mounted independently, simplifying installation and maintenance procedures, and ensuring adherence to stringent ISO and DIN dimensional standards. Ideal for use in vehicle differentials, wheel hubs, industrial gearboxes, and construction machinery, the SW 30208 guarantees reliability and extended service life, dramatically reducing unplanned downtime. The precise roller guidance system promotes lower operating temperatures and reduced friction, contributing to overall energy efficiency within the machinery. By choosing SW quality, industrial maintenance managers and OEM engineers invest in proven component performance that sustains high throughput and minimizes total cost of ownership in demanding, continuous-operation environments.

Key Features

  • High-purity steel construction ensures exceptional fatigue resistance and extended operational life.
  • Designed to absorb high combined radial and axial loads efficiently.
  • Separable components (cone and cup) facilitate easy mounting, inspection, and replacement.
  • Optimized roller geometry minimizes edge stress and promotes cooler running temperatures.
  • Precision machined to strict P6/ABEC-3 tolerance standards for reduced vibration and noise.
  • Suitable for high-torque applications in automotive, agriculture, and construction equipment.
