The SKF RGR-A hydraulic seal is a single-lip radial shaft seal built for hydraulic cylinder rods. Its reinforced body and sealing lip work together to hold hydraulic fluid in and keep contaminants out in linear motion. You will find it in agricultural machinery, road equipment, presses and general industrial hydraulics.

The RGR-A code works as a size reference. The letters place it in the SKF hydraulic seal range, and the numbers that follow give the dimensions in millimeters. Depending on the specific code, those numbers cover inner diameter, outer diameter and height. The -A ending marks a design variant inside the series, usually tied to the lip type or the body material. Reading the code correctly is the first step in matching a replacement.

Typical applications include hydraulic cylinders on tractors, harvesters, road equipment, cranes and presses. The same seals appear in lifting systems, hydraulic steering and linear actuators in metallurgical and construction work. In dusty, muddy or wet conditions, the RGR-A series provides a barrier against leaks and contamination that helps protect the hydraulic system over time.

To choose the right seal, confirm the housing and rod dimensions first. Inner diameter, outer diameter and height must line up with the designation. The lip and body material also need to suit the hydraulic fluid and the working temperatures. At installation, coat the lip with the same oil used in the system, keep it from twisting, and check that the rod is free of burrs or scratches. Good alignment and a polished rod surface support seal life. If the housing is worn, plan to replace or repair that component.

SKF RGR-A seals can be interchanged with equivalent products from other recognized brands when dimensions and application type match. A similar code is not enough: compare dimensions, material and lip configuration. Alternatives exist on the market, but interchangeability should be validated technically. We supply SKF and can help you find the right equivalence for your equipment without compromising hydraulic performance.
