Ball Bearings Production Business. Deep Groove Ball Bearings and Roller Bearings Manufacturing Industry
Deep groove ball bearings are the most common type of ball bearing. They are commonly used in electric motors and in household appliances, car motors, office machinery, automation control, and garden and household tools. They have deep raceway grooves and their race dimensions are close to the dimensions of the balls that run inside.
Deep groove ball bearings come in many sizes, materials and varieties according to consumer needs, including special industrial uses such as high-temperature applications. High-temperature bearings are made to withstand temperatures up to 350°C (660°F) and are suitable for machines used in the metals industry or for industrial ovens.
Deep groove ball bearings are among the most widely used type of bearing in the world. They can operate at high speeds and can carry radial and (limited) axial loads. They are commonly used in electric motors, compressors, fans, and conveyors.
Deep Groove Ball Bearing is a common type of bearings and it is used in several industries from heavy machinery to high precision apparatus. This type of bearings consists of four elements that include inner ring, outer ring, cage that holds balls and ball bearings. Because of the flat surface on outer ring and inner ring, Deep Groove Ball Bearings provides a larger area of contact that delivers high performance and high load capacity. Although Deep Groove Ball Bearings come in hundreds of models and sizes with different design and even different material used in inner ring, outer ring and the cage but basically they are categorized in 4 main sections.
Applications:
· Electric Motors
For electric motor manufacturers and those involved with the refurbishment of motors, deep groove ball bearings will be a familiar sight. Not every motor, however, is the same and selecting the right bearing can make a big difference.
· Electrical Goods
From photocopiers to washing machines, deep groove ball bearings are an important component. In many instances their specification is critical
· General Machinery
Compressors, pumps, gearboxes and fans are amongst the many other machines that are reliant on deep groove ball bearings. In each case, however, the demands on the bearing may be very different.
Many industries benefit from the use of Deep Groove Ball Bearings:
· Agricultural
· Food Processing
· Machine Tool
· Material Handling
· Medical / Pharmaceutical
· Printing
· Railway and Transportation
· Wind Energy
Roller Bearings
Roller bearings — also known as rolling-element bearings — are similar to ball bearings in that they are designed to carry a load while minimizing friction.
Roller bearings come in a wide range of shapes and sizes, and can be customized for specialized situations. Also, the use of flanges, cages, and multiple bearing rows can allow for higher performance to meet specific application needs.
Roller bearings extend the working life of wheels, pulleys, fans, pumps, compressors, and other rotating parts by reducing friction and enabling parts to move smoothly. They have a wide, flat bearing to provide stability in high-speed applications with high radial loads. Radial loads exert force across the diameter (radius) of the shaft, such as those exerted by the load supported by a pulley or wheel.
Tapered roller bearings, cylindrical bearings, and combination bearings support axial and radial loads, such as those encountered on vehicle axels where there force is both through the wheel and along the wheel axis. Needle roller bearings support high speed, high radial loads in confined spaces. Spherical roller bearings support heavy shock loads where misalignment is a risk, such as wind turbines, pumps, paper processing, and fans. Tapered roller bearing cones and cups support high radial and axial loads and are used for such things as axels and gear boxes.
Roller Bearing Types and Applications
There are thousands of different types of roller bearings available to meet specific application requirements. Emerson Bearing offers a broad selection of roller bearings, including the following popular types:
· Cylindrical Roller Bearings
These bearings feature rollers that are longer than their diameter, and can tolerate higher loads than ball bearings. Our cylindrical roller bearings can carry heavy radial loads and are able to be used in high-speed applications.
· Needle Roller Bearings
This type of bearing is thinner than conventional roller bearings and can be designed with or without an inner ring. Needle roller bearings are ideal for dealing with radial space constraints in heavy-load, high-speed applications. Drawn cup styles allow for high load capacities and large grease reservoirs while still offering a slim cross-section design. These bearings are offered with inch or metric seals.
· Spherical Roller Bearings
These can carry heavy loads even when dealing with misalignment and shaft deflection. They can be designed to have cylindrical or tapered bores for mounting with or without a sleeve adapter. Available with various internal clearances and retainer options, spherical roller bearings can handle axial loading in either direction as well as heavy shock loads. These bearings are available in bore dimensions ranging from 20 mm to 900 mm.
· Taper Roller Bearings
These bearings can support radial and thrust loads. They can only handle unidirectional axial loads, so a second laterally reversed bearing is required for counter stay. Taper roller bearings are available in inch and metric sizes.
Roller bearings are used in a wide range of applications, from heavy equipment and machinery to power generation, manufacturing, and aerospace.
