LM102949/10 PFI Single Row Tapered Roller Bearing 45.24x73.43x19.56 mm

What is the LM102949/10 PFI Bearing?

The LM102949/10 PFI is a single row inch series tapered roller bearing engineered to support high combined radial and axial loads. The bearing consists of a separable cone (LM102949) with tapered rollers and a matching cup (LM102910), allowing accurate preload adjustment and simplified installation. This design provides excellent rigidity, reliable load distribution and dependable performance in automotive, agricultural and industrial equipment.

Construction and Operating Principle

The LM102949/10 belongs to the family of single row tapered roller bearings.

Key design features include:

• Single row tapered roller bearing
• Inch series design
• Separable cone and cup assembly
• Pressed steel cage
• Adjustable preload and internal clearance
• Designed for combined radial and axial loads

The tapered roller geometry distributes forces efficiently, enabling the bearing to withstand heavy operating loads while maintaining accurate shaft alignment.
