The SKF RGR-A series hydraulic seal is a single-lip radial shaft seal designed for hydraulic cylinder rods. Its geometry with a sealing lip and reinforced body retains hydraulic fluid and excludes contaminants in linear motion applications. It is used in agricultural machinery, road equipment, presses and industrial hydraulic systems. MR Accesorios Industriales carries this line.

The RGR-A series designation is read as a dimensional code: the letters identify the SKF hydraulic seal category, and the numbers that follow indicate the dimensions in millimeters. The codes indicate the seal dimensions: inner diameter, outer diameter and height in millimeters, depending on the code. The -A suffix distinguishes a design variant within the series, generally associated with the lip type or body material. Knowing these dimensions is key to selecting the correct replacement part.

These seals are used in hydraulic cylinders of agricultural machinery, harvesters, tractors, road equipment, cranes and presses. They are also present in lifting systems, hydraulic steering and linear actuators in the metallurgical and construction industries. In Argentina, they are common in equipment from recognized brands operating under severe conditions, where dust, mud and moisture demand reliable sealing. The RGR-A series offers an effective barrier against leaks and contamination, contributing to the service life of the hydraulic system.

To select the correct seal, verify the housing and rod dimensions: inner diameter, outer diameter and height must match the designation. The lip and body material must be compatible with the hydraulic fluid and working temperatures. During installation, lubricate the lip with the same system oil, avoid twisting and make sure the rod has no burrs or scratches. Proper alignment and a polished rod surface extend seal life. If the housing shows wear, consider replacing or repairing the component.

SKF RGR-A series seals can be interchanged with equivalent products from other recognized brands, as long as the dimensions and application type match. It is not enough for the code to be similar: dimensions, material and lip configuration must be compared. There are alternatives from different manufacturers on the market, but interchangeability must be technically validated. MR Accesorios Industriales sells SKF and can advise you on the right equivalence for your equipment, without compromising hydraulic system performance.
