The SKF RGR-A series hydraulic seal is a single-lip oil seal designed for hydraulic cylinder rods. Its geometry with a sealing lip and reinforced body allows it to retain hydraulic fluid and exclude contaminants in linear motion applications. It is used in agricultural machinery, road equipment, presses and industrial hydraulic systems. MR Accesorios Industriales distributes this line, with more than 80 years of experience in the field.

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. For example, RGR 22X25X4.2-A corresponds to a seal with 22 mm inner diameter, 25 mm outer diameter and 4.2 mm height. Likewise, RGR 40X45X5-A has 40 mm inner, 45 mm outer and 5 mm height. 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.

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 in severe conditions, where dust, mud and humidity 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 ensure the rod has no burrs or scratches. Proper alignment and a polished rod surface extend seal life. If the housing shows wear, evaluate 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 distributes SKF and can advise you on the right equivalence for your equipment, without compromising hydraulic system performance.
