The wear ring centers the piston within the hydraulic cylinder bore, absorbs lateral and transverse forces, and prevents metal-to-metal contact -- protecting cylinder walls, seals, and the piston rod during operation. Replacing a worn or damaged wear ring restores proper cylinder alignment, extends seal life, and keeps the arm circuit performing at full capacity.\u003c\/p\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003cul\u003e  \u003cli\u003eBore: 110 mm\u003c\/li\u003e  \u003cli\u003eApplication: Arm Cylinder (AT154402)\u003c\/li\u003e  \u003cli\u003ePart Type: Cylinder Wear Ring \/ Guide Bushing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatible Models\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eFits John Deere (Fits JD) Excavator:\u003c\/strong\u003e 490E\u003c\/p\u003e\u003ch4\u003eReplaces Part Number(s):\u003c\/h4\u003e\u003cp\u003eAT153936, AT153936-A\u003c\/p\u003e\u003cp\u003eNew aftermarket replacement part - not remanufactured, not used.\u003c\/p\u003e","brand":"Reliable Aftermarket Parts, Inc® -OD","offers":[{"title":"Default Title","offer_id":17721859375155,"sku":"AT153936","price":16.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0079\/4060\/3955\/files\/AT153936_01.jpg?v=1757878547","url":"https:\/\/www.reliableaftermarketparts.co.uk\/products\/at153936-cylinder-wear-ring","provider":"Reliable Aftermarket Parts, Inc®","version":"1.0","type":"link"}
