SKF PI series radial shaft seals are lip seals that keep lubricant in and contaminants out of rotating shaft applications. They are commonly found in gearboxes, pumps, electric motors and power transmission equipment. MR Industrial Accessories LLC supplies this line to customers across the United States and in several Latin American countries. To request a quote, send the part number via WhatsApp or email.

The PI code tells you the seal type and its key dimensions. Take PI 202320: the bore is 20 mm, the outside diameter is 23 mm and the width is 20 mm. In the same way, PI 455030 has a 45 mm bore, a 50 mm outside diameter and a 30 mm width, and PI 808540 has an 80 mm bore, an 85 mm outside diameter and a 40 mm width. Use these figures to match the seal to your shaft and housing.

You will find PI seals in gearboxes, centrifugal pumps, electric motors, compressors, machine tools and power transmission equipment. They also appear in food, chemical and petrochemical plants, where keeping lubricant in and contamination out matters. The design suits rotating shafts at moderate speeds and in demanding conditions.

When choosing a PI seal, check the shaft diameter, the housing bore and the space available for width. Shaft concentricity and surface finish, plus alignment between shaft and housing, all affect performance. Lubricate the sealing lip before installation to avoid damage. In dusty or humid areas, consider versions with an auxiliary lip or a different material. Proper tools and careful fitting help the seal last.

PI series seals can replace equivalent products from other brands when dimensions and lip type match. During replacement, compare the lip material and the spring as well as the dimensions. Nitrile, viton and other elastomers are available; the choice depends on temperature and the fluid being retained. Our team can suggest equivalents and help you choose.
