Heat treatment causes discoloration and oxide deposits to develop on the balls. The balls undergo a descaling process to remove these spots. An acidic compound, or another chemical agent, is used during descaling to remove any build-up from the metal balls.

Once the excess material has been removed and the balls are relatively round, they undergo a heat-treating process to strengthen and harden the material. The steps include:

Once manufacturing is complete, the balls are washed to remove leftover residue. The clean metal balls are then inspected for size and signs of scratches or other defects.

For articulation/swivel joints, we recommend a combination of a maintenance-free spherical plain bearing used with a high load capacity four-point bearing.

Excess material, known as burrs or flash, must be filed away from the metal ball. The flashing process (filing) occurs while the metal is still soft and not yet perfectly rounded. While there are two machining variations commonly used by manufacturers, both involve rolling the balls between two metal plates.

Ball bearings consist of rolling elements that maintain separation between the inner and outer rings of the component. Using ball bearings reduces friction, allowing for a smooth, high-speed motion for sustaining axial and radial loads. Ball bearings can be developed for different speeds, loads, and applications.

Applications that require high-speed axial load support can benefit from ball thrust bearings designed to handle bi-directional axial loads. The bearings feature rings that contain raceway grooves, with bore dimensions ranging from 10 mm to 560 mm.

Once the balls are relatively round and hardened, the next phase involves grinding the balls to achieve proper size and improve the roundness geometry. Similar to soft grinding, the balls get rolled between a fine-grit grinding wheel and a steel plate.

Multiple tolerance grades, internal clearances, and cage designs are available to meet the precision and speed requirements of a specific application.

For 50+ years, Emerson Bearing has developed and maintained a reputation for distributing high-quality roller and ball bearings, serving the needs of both international and domestic customers.

A vast range of industries utilize ball bearings, which serve a wide variety of purposes in a broad range of processes. To learn more about the bearing applications, click here.

Selecting the proper ball bearing is essential to ensure optimal reliability and performance for a specific application, with benefits that include:

Control bearings are compact and able to sustain high radial loads. Offered in both sealed (PTFE) and open designs, cadmium plating is available for external surfaces, excluding the bore. Our control bearings cannot be used in aircraft and airframe applications but are certified for general commercial use.

Other ball bearing designs are available with separate thrust and radial roller bearings in a single assembly. Cartridge designs include the bearings, housing, and seal in one component.

The material used and the overall design features of a ball bearing can vary drastically depending on the application requirements. Commonly used materials include:

The accurate diagnosis of a bearing failure is imperativeto prevent repeated failures and their additional expenses.This comprehensive guide to bearing failures outlines themany ways bearings can and do fail.

Deep groove radial ball bearings are highly effective in handling heavy radial loads and relatively low bidirectional thrust. They are usually used in high-speed precision applications and include rubber seals or enhanced metal shields as needed.

Emerson Bearing is a leading distributor of rolling and ball bearings, offering a vast array of options for customers across many diverse industries. We are proud to supply products from industry-leading brands and have the largest inventory of bearings at multiple price points on the East Coast.

Miniature/instrumentation ball bearings provide dependable, high performance within small envelope dimensions for moderate thrust and radial load at low operating torque speeds.

The manufacturing of steel balls includes a steel rod or wire, which gets cut into small pieces (slugs) during the first step of the process. The slug is then fed into a header machine, where the metal balls undergo a cold-forming process (heading).

Millions of ball bearings are produced annually, with chrome steel being the most commonly used material. Chrome steel bearing balls are almost perfectly rounded and offer a polished, mirror-like finish to provide precision rotary motion in hundreds of industrial applications, some of which include:

The final step in the manufacturing process is lapping. This super-finishing process improves the geometry or surface finish, removing trace amounts of material so the ball achieves tight tolerance requirements.

When an axial load is unidirectional, our single-row angular contact bearings can sustain radial, axial, and combined loads. Designs with small contact angle designs can allow for high-speed operations, while larger contact angles can accommodate higher axial loads. The bore diameter can vary between 10 mm to 170 mm, with cages and retainers available using the following materials:

At Emerson Bearing, we offer customers a full range of high-quality ball bearings, including the following popular types:

Ball screw support bearings prove beneficial in applications involving ball screws or lead screws. Most have angular contact for ball screw support with a steep angle contact often found in duplex, triplex, and quadruplex configurations.
