Sprint Birdcage Bearing 28mm

The Sprint Birdcage Bearing 28mm from ALLSTAR PERFORMANCE is a precision roller bearing engineered for high-speed racing and motorsports applications where reliability under extreme load conditions is non-negotiable. This bearing serves as a critical component in sprint car suspensions and drivetrain assemblies, where it manages radial and axial loads while maintaining rotational freedom at elevated RPMs. Racers and chassis specialists depend on birdcage bearings to reduce friction, extend service life, and maintain consistent performance lap after lap in competitive environments.

Built from hardened steel with a 2.758-inch inner diameter and 3.935-inch outer diameter, the Sprint Birdcage Bearing 28mm delivers robust load distribution across its 1.1-inch width and roller design. The birdcage design—a cage-and-roller configuration—reduces friction points compared to ball bearings and excels under sustained lateral and vertical forces typical in sprint car suspension geometry. Steel construction ensures durability against thermal cycling and shock loads encountered during aggressive cornering and acceleration, while the precision tolerances maintain proper fit within OEM and aftermarket spindle assemblies.

Sprint car teams, short-track racers, and fabricators building or maintaining high-performance suspensions will find this bearing essential for spindle assemblies and hub applications. Its compact 28mm cross-section allows integration into space-constrained mounting points without sacrificing load capacity. Installation requires proper seating in a compatible spindle bore; verify inner and outer diameter specifications against your suspension design before ordering. Regular inspection and re-greasing during maintenance intervals will maximize bearing life and maintain the responsive handling characteristics that competitive drivers demand.
