At Rubrings Company, we supply high-quality oil seals—also known as rotary shaft seals, grease seals, or dirt seals—designed to protect and enhance the performance of mechanical systems. Our oil seals are engineered to retain lubricants such as oil or grease within a housing or casing while preventing the entry of contaminants like dust, dirt, and moisture. These seals are essential for maintaining the efficiency and longevity of machinery by closing the gap between stationary and moving parts. Commonly used in high-speed rotating shafts operating under low pressure, oil seals are among the most widely used dynamic sealing components in industrial applications. Wherever bearings are used to support a rotating shaft, you’ll often find a Rubrings oil seal ensuring that lubrication remains inside and harmful particles stay out. Our oil seals typically consist of a rubber elastomer bonded to a metal casing, with many featuring a garter spring to maintain consistent pressure of the sealing lip against the shaft for effective sealing performance. Rubrings oil seals are trusted across automotive, manufacturing, and heavy industrial sectors for their durability, reliability, and precision engineering.
Rod Seals are the most critical seals in a hydraulic cylinder. Rod Seals are radial internal seals. Rod Seals are press-fit into a housing bore with the sealing lip contacting the shaft. Rod Seals are also referred to as shaft seals sometimes. Rod Seal failure could result in fluid leakage. Special care should be shown in selecting the best Rod Seal for your sealing application. Rod Seals act as a dynamic seal along its inner diameter and static along its outer diameter. Rod Seals are affected by changes to the rod surface and fluid temperatures. Rod Seals often see the highest pressure variation. Rod Seals are often the decisive factor in the function of a hydraulic cylinder.
