Midget Birdcage Bearing Angular Contact

The MPD Midget Birdcage Bearing Angular Contact (SKU: MPD20120) is a precision double-row angular contact bearing engineered for high-speed racing applications where reliability under extreme conditions is non-negotiable. With inner diameter of 2.165 inches and outer diameter of 3.543 inches, this bearing delivers the load capacity and angular contact geometry required in midget and sprint car suspensions, transmissions, and drivetrain assemblies where vibration isolation and durability are critical.

The 1.415-inch width and double-row angular contact design enable this bearing to handle both radial and axial loads simultaneously—a key advantage in racing where cornering forces, acceleration, and braking loads converge on suspension pivot points and transmission support bearings. The steel construction in natural finish resists corrosion while maintaining dimensional stability across temperature cycles common in competitive racing environments. Angular contact bearings like this one are optimized to operate at higher rotational speeds and under combined loading conditions that standard deep-groove bearings cannot safely accommodate, making them the engineering standard for serious racing applications.

This bearing is specified for midget racing where weight-sensitive platforms demand compact, high-performance components. Buyers restoring or upgrading midget race cars, sprint cars, or similar competition vehicles will recognize the MPD Midget Birdcage nomenclature as the OEM standard for these platforms. Racers and race shop technicians sourcing replacement bearings, chassis components, or upgrade kits will find this bearing essential for maintaining the precise tolerances and load ratings that competitive racing demands.
