The sealing element is produced from a high performance Nitrile rubber. Smaller sizes only for applications such as needle bearings and grease seal but the outside surface has a ribbed design. R type with two sealing lips, used for sealing two separate media. This allows for equal contraction and expansion of the materials during operation, preventing leakage from occurring. In order to prevent leakages due to a hydrodynamic pumping effect is it necessary that the sealing lip contact area on the sleeve or shaft is without any traces of machine lay. Moreover, oil seals with a rubber case can seal a lightly damaged housing much better than metal cased oils seals. It is a simple device for excluding dust, dirt, water or any other contaminant whilst retaining lubricant in rotary shaft equipment. Nitrile presents great stability of working attributes such as high tensile strength, high abrasion resistance, and low compression set combined with low cost. Based on the application of the oil seal, the outer skin layer tends to differ. Complete list of elastomers available from Precision Polymer Engineering with links to download material datasheets. Rubber outer diameter with a carbon steel insert. The spring on the lip of the oil seal provides support to the lip and prevents the lubricant from leaking outside and also prevents contaminants from entering.
