CAT 5S-2106 Seal","description":"\u003cdiv\u003e\u003cp\u003eCAT 5S-2106 Seal is a genuine Caterpillar lip-seal for rotating shafts, sized for a 50.80 mm (2.00 in) shaft diameter. The lip-type design is engineered to ride over the shaft on a film of oil, promoting long seal life and reliable lubrication retention. The Cat part number is 5S-2106 (often listed as 5S2106) and is sold through Cat® Parts Store as the authentic replacement option. This seal provides a precise fit for applications requiring a 50.80 mm shaft seal, aligning with Caterpillar’s standard lip-seal family to protect internal lubricants from contaminants. When replacing a worn seal on a Cat machine or hydraulic component that uses a 50.80 mm shaft, 5S-2106 offers a like-for-like Cat replacement that preserves sealing performance and compatibility with Cat housings. The specification emphasis is the shaft diameter and lip-seal design, ensuring correct fitment and minimizing downtime by using an authentic Caterpillar part.\u003c\/p\u003e\u003c\/div\u003e","brand":"Caterpillar","offers":[{"title":"New Surplus No Box","offer_id":51677845586222,"sku":null,"price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_16db8cfc-3609-4d46-b2e3-72f0129d77ec.jpg?v=1769568322","url":"https:\/\/plgautomation.com\/products\/caterpillar-inc-cat-5s-2106-seal","provider":"PLG Automation ","version":"1.0","type":"link"}
