Deep groove ball bearings are one of the most widely used types of rolling bearings, and are favored for their simple structure, wide range of uses, and reliable performance. The following are their main uses and applicable scenarios:
1. Bear radial loads
Main function: The core purpose of deep groove ball bearings is to bear radial loads perpendicular to the axis (such as belt drive and force generated by gear meshing).
Typical applications:
Rotor support in motors and generators.
Axle support for rotating equipment such as industrial pumps and fans.
Automotive hubs (some light vehicles) or transmission systems.
2. Bear certain axial loads
Bidirectional axial loads: Although mainly radial loads, deep groove ball bearings can also withstand a certain degree of bidirectional axial loads (forces along the axis).
Applicable scenarios:
Occasions with low axial loads (such as small gearboxes, household appliances).
Devices that require simplified design to avoid the use of additional thrust bearings.
3. High-speed rotation scenarios
Low friction design: The rolling element and groove contact points of deep groove ball bearings have low friction and are suitable for high-speed operation.
Typical applications:
Power tools (electric drills, angle grinders, etc.).
Machine tool spindles (medium and low load high-speed spindles).
Auxiliary equipment in automobile engines (such as cooling water pumps).
4. General machinery field
Compact structure: small size, easy to install, suitable for scenarios with limited space.
Common equipment:
Household appliances (washing machines, air conditioning fans, vacuum cleaners).
Office equipment (printers, scanners).
Agricultural machinery (harvesters, tractor transmission parts).
5. Low maintenance demand scenarios
Sealed/dustproof design: Some deep groove ball bearings are equipped with sealing rings or dust covers, suitable for dusty and humid environments.
Application examples:
Food processing machinery (needs corrosion protection and pollution prevention).
Conveyor belt rollers in automated production lines.
Hub bearings for bicycles and scooters.
6. Special variant uses
Silent type: Optimized low-noise bearings are used for precision instruments or household appliances (such as computer fans).
High temperature or corrosion resistant type: ceramic balls or stainless steel are used, suitable for extreme environments (such as chemical equipment, high temperature ovens).
Unsuitable scenarios
High axial load: angular contact ball bearings or thrust bearings need to be used instead.
Heavy impact load: cylindrical roller bearings or spherical roller bearings need to be selected.
Extreme centering error: spherical bearings need to be used.
Summary
Deep groove ball bearings have become a "jack of all trades" element in mechanical design due to their versatility, economy and reliability, and are suitable for a wide range of fields from micro motors to heavy equipment. When selecting, factors such as load type, speed, and environment need to be considered, and other bearing types can be used in combination when necessary.
