They are engineered to facilitate the smooth operation of your equipment, serving as a barrier to prevent the leakage of oils and greases while also keeping foreign substances from entering. VM type seals are often used in larger shaft sizes or when a smaller shaft requires extra strength. This is due to the metal-cased outside diameter which has a very stable construction and offers a better-protected sealing member in comparison to the open-backed style. The M type oil seals feature a lead-in chamfer and have an additional inner rubber lining particularly fit for protecting the case from erosive fluid. The VM features a single-sealing nitrile rubber lip on the inside diameter.\u003cbr\u003e\n  \u003cstrong\u003eBenefits: \u003c\/strong\u003eExcellent wear resistance, good running properties, high resistance to chemicals and petroleum-based fuels including petrol, diesel and LPG.\n\u003c\/p\u003e","brand":"NAK","offers":[{"title":"Default Title","offer_id":54118201917781,"sku":"30x40x4_VM_NAK","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/1491\/3109\/files\/nak_metal_pack1_080b0e10-0ca9-49bf-a795-5b8ccdee6081.jpg?v=1785757280","url":"https:\/\/simplybearings.com\/products\/30x40x4-vm-nak","provider":"Simply Bearings Ltd - Ball Bearings, Oil Seals, O-rings, V-Belts, SKF","version":"1.0","type":"link"}
