Product Description

Double row angular contact ball bearing HRB 3204 ATN 5204

Angular contact ball bearings are particularly suitable for carrying combined (axial and radial) loads. Sometimes, they also can carry pure axial load and operate in higher speed. Under radial load, axial component force will be produced which must be counteracted. So the bearings are normally adjust against a second bearing.
Single row angular contact ball bearings can carry axial load acting in one direction only. In many applications, angular contact ball bearings in pairs or muti-arrangement should be used. The axial load carrying capacity of angular contact ball bearings increases with the increase of contact angle.

FAQ1: What applications of double row angular contact ball bearings are in machinery?

Double-row angular contact ball bearings are essential in machinery where shafts need to be positioned precisely and must handle a combination of heavy radial and axial loads. They are commonly used in:
1. Pumps and Compressors: To support the impeller and shaft under both radial and axial forces.
2. Gearboxes: In high-speed gearboxes to ensure precise gear meshing.
3. Electric Motors: In motors that experience both a radial load from the rotor and a thrust load from a fan or other attached components.
4. Machine Tools: In spindles and feed mechanisms that require high rigidity and accuracy.

FAQ2: What are the load and speed ratings of HRB 5204 angular contact bearings?

The load and speed ratings of HRB 5204 angular contact bearings are as follows:
Dynamic Load Rating (Cr): Approximately 20.4 kN (kilonewtons). This is the load the bearing can handle at a given speed for a defined number of revolutions.
Static Load Rating (C0r): Approximately 12.5 kN (kilonewtons). This is the load the bearing can handle without any rotation.
Limiting Speed: The limiting speed depends on the lubrication. For grease lubrication, it is approximately 9,500 r/min, and for oil lubrication, it is 13,000 r/min. These ratings demonstrate the bearing’s capability to handle both high loads and high speeds, making it a versatile component.
