This Cat part, manufactured as Cat Plast wear ring, provides a low-friction bearing interface that guides the piston and helps control wear between the piston and bore. The wear ring features a bore diameter of 177.8 mm, aligning with Cat's piston-guide specifications for compatible hydraulic cylinders. Identified by the part number 9J-0711 (also listed as 9J0711 by some catalogues), this wear ring is designed to be installed where Cat hydraulic cylinders require a dedicated piston guide wear ring. Typical applications include replacement in Cat hydraulic systems where a 177.8 mm bore wear ring is specified, serving to improve cylinder life and piston alignment. As a genuine Cat component, it is intended for use with Cat equipment where the 9J-0711 specification is called out by the service or parts manual. \u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e","brand":"Caterpillar","offers":[{"title":"New Surplus No Box","offer_id":51677819994414,"sku":null,"price":44.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_5453c35b-7560-4235-9c66-e0a9360ea7ab.jpg?v=1769568098","url":"https:\/\/plgautomation.com\/products\/caterpillar-9j-0711-wear-ring","provider":"PLG Automation ","version":"1.0","type":"link"}
