| Bearing NO. | QJ304-XL-MPA |
| Category | Four-point contact bearing |
| Overview | QJ304-XL-MPA Four point contact bearing with solid brass cage. |
| Features and benefits | The four-point contact ball bearing is a separable structure, and a single bearing can replace the angular contact ball bearing combined with the front or the back. |
| Compared with other ball bearings, four-point contact ball bearings have smaller axial clearance and higher limit speed when the radial clearance is the same. | |
| Four-point contact ball bearings are suitable for bearing pure axial load or combined axial and radial loads mainly based on axial load. Because it is a double half inner ring (or outer ring), the number of balls is increased, and it has a larger bearing capacity. | |
| It can bear radial load and two-way axial load, and can limit the axial displacement in two directions, but it occupies less axial space than the double row angular contact ball bearing of the current specification. | |
| Application | Four point contact bearings are often combined with a radial bearing and used as an axial bearing with radial clearance in a housing. |
