  • 7002A-Angular contact ball bearings for precision machinery
PREV：7002A DTA-Angular contact ball bearings for precision machinery NEXT：7002C SU-Angular contact ball bearings for precision machinery
Product description Technical parameter
Precision angular contact ball bearing, belongs to the deep groove ball bearing deformation structure, suitable for all kinds of precision machinery selection, this series of bearings can bear radial load and axial load at the same time, can work at a higher speed. The larger the contact angle, the higher the axial load carrying capacity. According to the axial load size, contact angle is mainly divided into C-15 degrees, AC-25 degrees, A-30 degrees, B-40 degrees type structure, small friction coefficient, high limit speed, high manufacturing accuracy, can provide high-speed ceramic ball series bearings and sealed series bearings, cage mainly organic processing window brass cage, steel plate stamping cage, glass fiber reinforced nylon cage (nylon), and phenolic Laminated cloth tube cage (rubber wood), also can provide universal pair and any pair combination bearings. Mainly used in: machine tool spindles, high frequency motors, gas turbines, centrifugal separators, small car front wheels, differential pinion shafts, booster pumps, drilling platforms, food machinery, indexing heads, welding machines, low-noise cooling towers, electromechanical equipment, coating equipment, machine tool groove plates, arc welding machines, water pumps, modules, and support seats.

1.Can the Rated Dynamic Load change based on the direction of the applied load?
The Rated Dynamic Load (C) of a bearing can be influenced by the direction of the applied load. The Rated Dynamic Load is a measure of the load at which a group of identical bearings is expected to achieve a rating life of one million revolutions with 90% reliability. This load is typically defined for radial loads in the case of radial bearings and axial loads in the case of thrust bearings.
In the case of angular contact ball bearings, which are designed to handle both radial and axial loads, the Rated Dynamic Load is often specified for radial loads. However, the direction of the applied load can affect the load-carrying capacity of the bearing. Here's how it generally works:
Radial Load:When a radial load is applied, the load is perpendicular to the axis of rotation. The Rated Dynamic Load specified for radial loads is applicable in this scenario.
Axial Load:When an axial load is applied, the load is parallel to the axis of rotation. The axial load-carrying capacity of the bearing may be different from its radial load capacity.
For angular contact ball bearings, there is often a separate axial load rating (C0a) specified, which is the axial load that a group of identical bearings can withstand without excessive wear.
Combined Loads:In real-world applications, both radial and axial loads may be present simultaneously. The bearing's overall load-carrying capacity under combined loads will depend on the magnitudes and directions of the radial and axial loads.
Equivalent Load:To simplify the analysis of combined loads, an equivalent radial load (P) is often calculated. The equivalent radial load takes into account both radial and axial loads and allows for a direct comparison with the Rated Dynamic Load specified for radial loads.
It's crucial to consult the bearing manufacturer's documentation and tables, as they provide valuable information regarding the bearing's load ratings, load capacities under different conditions, and how to calculate equivalent loads. Additionally, engineers should consider factors such as misalignment, preload, and the specific application requirements when determining the appropriate load ratings for a given bearing and load direction.
The Rated Dynamic Load (C) of an angular contact ball bearing is a standardized parameter that represents the maximum dynamic radial load (for radial bearings) or axial load (for thrust bearings) that a group of identical bearings can endure under specific operating conditions while achieving a rating life of one million revolutions with 90% reliability.
The Rated Dynamic Load is typically expressed in Newtons (N) or pounds-force (lbf) and is specified by bearing manufacturers based on standardized testing procedures. For angular contact ball bearings, the Rated Dynamic Load is often provided for radial loads, as these bearings are designed to handle both radial and axial loads.
