Deep Groove Ball Bearings

Deep groove ball bearings are bearing the most common type of bearing that is mainly used for pure radial loads, but also can stand radial load while small axial load. Deep groove ball bearing friction coefficient is small, but limiting speed is high. Deep groove ball bearing structure is simple, and manufacturing costs is low, widely used in transmission, instrumentation, motors, household electrical, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery and engineering machinery.

Type of ball bearing

Deep groove ball bearings or single row radial ball bearings are the most widely used bearings in all general industries.
They utilize uninterrupted raceways to make them most suitable for radial loads. Radial ball bearings are usually equipped with a pressed steel cage, but machined brass or molded nylon materials are also available. Bearings with locating snap rings on the outer diameter are also provided.

Bearing types are divided into single row deep groove ball bearings, double row deep groove ball bearings, thrust deep groove ball bearings, centripetal deep groove ball bearings, stainless steel deep groove ball bearings, deep groove ball bearing pullers, and outer ring grooved bearings , Flange deep groove ball bearings, 6001rs ceramic bearings, grooved ball bearings, slotted ball bearings, high-speed deep groove ball bearings, deep groove thrust ball bearings, sealed deep groove ball bearings, miniature deep groove ball bearings, inch deep groove balls Bearings, hybrid deep groove ball bearings, slotted roller bearings, V-groove deep groove ball bearings,
China u-groove roller bearings.

They are commonly used in electric motors and household appliances, automotive motors, office machinery, automation control, and gardening and household tools. They have deep raceway grooves, and their raceway size is close to the size of the ball running inside.

Deep groove ball bearings have a variety of sizes, materials and varieties according to consumer needs, including special industrial uses such as high-temperature applications. High-temperature bearings can withstand temperatures up to 350°C (660°F) and are suitable for machines used in the metal industry or industrial ovens.

They are divided into two designs: there are single-row single-row deep groove ball bearings; there are also double-row bearings, which have two rows of ball bearings. They can also be made into different sizes and different loads according to their applications, from miniature ball bearings for light loads and small components to large deep groove ball bearings and heavy load deep groove bearings.

Replacing deep groove ball bearings with plain bearings can provide a range of benefits, including reduced costs, reduced maintenance, greatly reduced noise at low speeds, and easier installation. Sliding bearings can also have higher load carrying capacity, simplified assembly, longer service life, smaller bearing seat size, assembly size and weight.

Installation unit

The ball bearing unit consists of a precision wide inner ring bearing assembled in a bearing seat made of cast iron or pressed steel. The device is pre-lubricated and designed to be slidingly fitted to the shaft. The locking method is set screw locking, eccentric self-locking or concentric. On cast iron and pressed steel devices, the outer diameter of the bearing and the inner diameter of the housing are spherical, allowing the bearing to rotate within the housing to accommodate the initial alignment.

There are many combinations of bearings and housings to adapt to various mounting surfaces, load requirements, shaft dimensions and size requirements.

Locking mechanisms include fixing screws, eccentric self-locking and ConCentra locking.

Bearing failure and how to prevent it

Bearings are the core of all rotating equipment, and the condition of the bearings often reflects the operating conditions of the machine.

There are many reasons for bearing damage. Problems such as misalignment, imbalance, looseness, and friction all send signals through the bearing and sometimes cause malfunctions. Since bearings are usually the most important mechanical component, failures can result in costly downtime, damage to adjacent components, and substantial repair costs.

9.5% of bearings fail due to working conditions and need to be replaced before the end of the life of the application machine. By choosing the right bearings for the right application, you can reduce unnecessary downtime, production losses, costs and damage.

1. Choose the right bearing design
2. Actively store bearings
3. Install the bearing correctly
4. Lubricate the bearings according to the manufacturer’s guidelines
5. Align the machine precisely
6. Balance your equipment
7. Additional diagnostic tests
