Double Row Ball Bearing

The Winters Double Row Ball Bearing (MPN 7311) is a precision-engineered component designed for demanding tactical, military, and law enforcement applications where reliability under extreme conditions is essential. This bearing serves as a critical load-bearing element in weapon systems, optics mounts, and equipment assemblies where rotational accuracy and durability directly impact mission success.

The double row configuration of this bearing distributes radial and axial loads across two parallel raceways, significantly increasing load capacity and operational lifespan compared to single-row alternatives. This geometry reduces friction, minimizes deflection, and maintains tight tolerances critical for precision applications—essential when firearm accuracy or equipment function depends on smooth, consistent rotational movement. Winters bearings are manufactured to exacting standards with hardened steel races and precision-grade balls, delivering the repeatability and longevity required in combat-proven equipment.

Operators in law enforcement and military roles rely on Winters double row ball bearings for their compact footprint and lightweight construction, which make integration seamless without compromising system balance or adding unnecessary weight to tactical platforms. The dimensions of 3.1 x 1.3 x 3.55 inches and a verified weight of 1.06 lbs ensure that this component meets the rigorous demands of tactical environments.
