SKF AS washers are retaining components fitted in needle bearings to keep the needles in position and facilitate assembly. They are used in assemblies where axial space is limited and a compact solution is required. MR Accesorios Industriales supplies this line, with more than 80 years of experience in the field. If you need to identify the right washer, send us the part number on WhatsApp and we will advise you.
The designation of these washers is read as AS followed by four digits that indicate dimensions. For example, AS 0619 corresponds to a washer with a 6 mm bore and a 19 mm outside diameter; AS 0821 has an 8 mm bore and a 21 mm outside diameter; AS 1024, 10 mm and 24 mm; AS 1226, 12 mm and 26 mm; AS 1528, 15 mm and 28 mm; AS 1730, 17 mm and 30 mm; AS 2035, 20 mm and 35 mm; and AS 2542, 25 mm and 42 mm. These part numbers allow you to select the washer according to the available space and the shaft diameter.
These washers are used in needle bearings, especially in applications where radial loads are significant and axial space is limited. In Argentina, they are found in agricultural machinery, transmission equipment, pumps, compressors, machine tools and conveying systems. They are also used in industrial equipment maintenance, where replacing standard components speeds up downtime. As part of the bearings category, they are critical to the correct operation of rotating assemblies.
To select the right washer, take into account the shaft diameter, the bearing outside diameter and the available space. It is important to verify that the AS washer is compatible with the corresponding needle bearing, since its function is to retain the needles and facilitate assembly. During assembly, make sure the washer seats correctly and does not interfere with rotation. Lubrication of the assembly also affects service life; follow the equipment manufacturer's recommendations.
As for equivalents, SKF AS washers can be interchanged with those from other manufacturers that follow the same dimensional designation, such as the AS series from other brands. However, it is essential to verify tolerances and surface treatment, as they may vary between manufacturers. For critical applications, consult the technical specifications of each supplier. MR Accesorios Industriales supplies SKF, which backs the quality of the component.

Frequently Asked Questions
- How do I identify the AS washer I need?
- The AS part number includes two measurements: the first two digits indicate the bore and the next two the outside diameter. For example, AS 1024 has a 10 mm bore and a 24 mm outside diameter. Check the dimensions of your bearing and choose the corresponding part number.
- Are SKF AS washers compatible with bearings from other brands?
- Yes, as long as the needle bearing has the same dimensions and design. The AS designation is standard, but verify tolerances and material. To be sure, ask us with the bearing part number and we will confirm compatibility.
- What lubrication do you recommend for a bearing with AS washers?
- Lubrication depends on the application: grease for high loads and low speeds, or oil for high speeds. Follow the equipment manufacturer's instructions. Proper lubrication extends bearing life and prevents premature wear.
