Spherical bearings are a type of bearing consisting of axially rounded raceways, allowing for accommodation of shaft misalignment. Types of spherical bearings include spherical ball bearings, spherical roller bearings
, spherical plain bearings, and spherical rod end bearings
. Spherical ball bearings are double-row, self-aligning bearings
featuring inner and outer rings encasing two rows of balls. They can be produced with straight or tapered bores, and specialize in temperature conservation in high-speed applications. The concave raceway in the outer ring allows the balls to operate over a wide range of contact angles. They often are available in multiple series with various maximum degrees of misalignment. Spherical roller bearings feature rolling elements similar to cylinders, and specialize in high load capacities and slow-speed applications. They are designed to accommodate severe misalignments and are extremely resistant to shock loads. Spherical plain bearings, or ball bushings, are designed to accommodate almost any operating environment. They come in a wide variety of materials, with combinations of steel, bronze, and thermoplastics or composites. They are suitable for heavy-duty vehicles, agricultural machinery, construction equipment, packaging and textile equipment, mining and logging equipment, and robotics. Spherical rod end bearingscomprise an eye-shaped head with integral shank, forming a spherical plain bearing housing unit; they are commonly used in applications where an articulating joint is required, such as aircraft control systems, steering links, and track rollers. Find the spherical bearing that suits your application; MRO Supply carries a wide variety of spherical bearings, of many types, materials, sizes, and manufacturers.
