SKF QJ 304 MA four-point bearing

Product detailed description

SKF QJ 304 MA is a four-point angular contact ball bearing designed for applications requiring high precision and reliability. This bearing is part of the Explorer series, which is known for its optimized internal geometry and improved materials, resulting in increased load capacity and extended service life.

The bearing has an inner diameter of 20 mm, an outer diameter of 52 mm and a width of 15 mm. The inner ring is split, which allows for easier mounting and dismounting. The bore profile is cylindrical, which is a standard shape for this type of bearing. The bearing is made of high-quality steel, which ensures wear resistance and high strength.

The bearing design includes a brass cage, which provides excellent wear resistance and stability at high speeds. The bearing is not equipped with a seal, which means it is uncovered and requires regular maintenance and lubrication.

The operating temperature range of the bearing is from -30 °C to +150 °C, which allows it to be used in various industrial applications. The bearing has normal radial clearance, which is suitable for most standard applications. The running accuracy is defined by the dimensional accuracy P6 and the operating accuracy P5, which guarantees high accuracy and reliability in operation.

SKF QJ 304 MA is ideal for applications where a combination of axial and radial loads is required, while its design allows it to absorb loads in both directions. Thanks to its properties, it is suitable for use in various industries, including mechanical engineering, the automotive industry and the energy industry. The weight of the bearing is 0.177 kg, which contributes to its easy handling and installation.
