HM807046/HM807010-B Timken Tapered Roller Bearing with Flange 50.80x104.775x36.513mm

The HM807046/HM807010-B Timken tapered roller bearing is a precision-engineered, single-row assembly designed to deliver outstanding performance in demanding industrial and automotive environments. Featuring a TSF (Tapered Single with Flange) design, this bearing incorporates a flanged outer ring (cup) to support accurate axial positioning and improved sealing alignment in through-bored housings.

Manufactured by Timken, this assembly includes the matched cone (HM807046) and flanged cup (HM807010-B), ensuring optimal internal geometry, load distribution, and long service life.

Key Features & Benefits

• TSF flanged cup design – Enables precise axial location and improved seal alignment
• High load capacity – Designed to handle combined radial and axial loads efficiently
• Separable construction – Cone and cup can be mounted independently for easier installation and maintenance
• Heavy-duty performance – Suitable for shock loads, high speeds, and harsh environments
• Premium Timken steel & heat treatment – Enhances durability and reduces wear

Design & Performance

The HM807046/HM807010-B utilises Timken’s advanced tapered roller geometry to minimise friction while maximising load-carrying capability. The flanged cup design ensures improved axial positioning and system rigidity, making it ideal for applications requiring precise alignment and secure bearing location.

Typical Applications

• Wheel hubs and axle systems
• Gearboxes and transmissions
• Agricultural and construction machinery
• Heavy-duty industrial equipment
