115 X 140 X 12 NITRILE OIL SEAL

Buna-N/Nitrile/NBR TC oil seal, item MOS-115-140-012-TC, for rotary shaft sealing, oil retention, grease retention, and bearing protection in industrial equipment. This rotary shaft seal is described as rubber covered OD, double lip, with spring based on the available attributes, giving customers a clear view of the lip design, spring detail, and outside-diameter construction when those details are available. The actual dimensions are 115 mm (4.528 inch) ID x 140 mm (5.51 inch) OD x 12 mm (0.472 inch) cross-section/height, making the part easier to compare against shaft size, housing bore, and seal width requirements. Oil seals are commonly used on gearboxes, motors, pumps, rollers, gear reducers, and rotating assemblies where lubricant must stay inside the housing while dirt, moisture, and debris are kept out. Buna-N/NBR is widely used for rotary sealing where compatibility with many oils and greases is required. The wording naturally supports product searches for oil seal, rotary shaft seal, nitrile oil seal, FKM oil seal, rubber covered OD seal, single lip oil seal, and double lip oil seal as applicable. Item MOS-115-140-012-TC is included for SKU-level identification in equipment records, drawings, maintenance lists, and reseller product catalogs.
