- a. Nitrile Rubber (NBR) – this is the most commonly used material. It has good heat resistance properties and has good resistance to salt solutions, oils, hydraulic oils, and gasoline. Operating temperatures are recommended from -40 to 248⁰ F (-40 to 120 deg.C). Nitrile also functions well in a dry environment, but only for intermittent periods. The disadvantage of this material is poor chemical resistance.
- Oil seals are critical components in various machinery and systems, providing a vital barrier between the moving parts and external contaminants. The 14x22x5 oil seal is a popular size due to its versatility and effectiveness in a wide range of applications. In this article, we will delve into the features, benefits, and proper usage of the 14x22x5 oil seal to help you make an informed decision when selecting or using this product.

What Are Oil Seals? Oil Seal Applications & Uses
-15 °C to + 180 °C
NBR rubber is above all resistant to oils, especially hydraulic oils, lubricants, petrol and other aliphatic hydrocarbons, diluted acids and lyes. Good physical values such as high friction resistance and ruggedness and good temperature resistance (-25 °C up to +120 °C, in part to -40 °C) give this natural rubber a wide range of uses.
Choosing the right oil seal
Garter springs are generally used when the lubricant is oil, as it provides the necessary downward force to maintain a tight seal. However, when grease is the lubricant, garter springs can often be eliminated. Due to its low viscosity, grease doesn’t require as much downward force to maintain an effective seal.
Oil seals, which are also referred to as radial shaft seals, rotary shaft seals, grease seals, or fluid seals, are used to close the gaps between fixed and moving parts of mechanical equipment. They are put between moving and stationary mechanical parts to make sure that moisture, contaminants, corrosive materials, and abrasives don’t cause any damage to these parts.

If necessary, lever it gently with a broad screwdriver blade, but take care not to bend the flange or damage the head.
Oil seals close spaces between moving or stationary mechanical components to prevent lubricants like grease and oil from escaping, while also preventing dust, dirt, moisture, and other contaminants from entering the seal. Also known as shaft seals, dirt seals, lip seals, or grease seals, the primary components of any oil seal include an inner metal ring, which provides structural support, and a spring, which provides interference for effective sealing.
The numbers 30-50-10 indicate the dimensions of the oil seal, specifically its inner diameter, outer diameter, and height. This measurement ensures that the oil seal fits perfectly into the designated space and effectively seals off any potential leaks.
