Aft liners (sleeves) are typically long, heavy items requiring a large melt capacity and associated machining capabilities. They are regularly supplied finish machined, requiring all of Spunalloys\u2019 experience, skill and infrastructure.<\/p>\n<p>Our large melting capacity and extended horizontal casting platform enables naval shaft liners to be supplied up to 5000mm in length in various corrosion resistant alloys, such as copper nickel, gunmetal, tin and phosphor bronze, nickel aluminium bronze, monel and Inconel. Spunalloys\u2019 in-house machining capabilities allow \u2018liners\u2019 to be supplied either proof or finish machined.<\/p>\n<p>Finish machining generally involves the bore [including water injection scrolls] with a proofed outside diameter to allow for \u2018sixing\u2019 when fitted to the ship shaft. Spunalloys developed unique and proprietorial solutions to meet the stringent acceptance criteria demanded for naval shaft liners. Spunalloys carries approvals for many major 1st and 2nd tier organisations, including UK MOD Approval to manufacture DEF STAN 02-830 (LG4) shaft liners, inspected in accordance with DEF STAN 02-304 part 1. Our experience and manufacturing capabilities allow us to support many of the world\u2019s naval forces, including USA\/NAVSEA.<\/p>\n                                        <\/div>\n                                    <\/div>\n                                                                    <\/div>\n                            \n                            \n                            \n                            \n                            \n                            \n                                                                                        <\/div>\n            <\/div>\n        <\/div>\n    <\/div>\n<\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":19,"menu_order":5,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-31","page","type-page","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Naval Propeller Shaft Liners - Spun Alloys<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/westleygroup.co.uk\/spunalloys\/naval-propeller-shaft-liners\/\" \/>\n<meta property=\"og:locale\" content=\"en_GB\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Naval Propeller Shaft Liners - Spun Alloys\" \/>\n<meta property=\"og:url\" content=\"https:\/\/westleygroup.co.uk\/spunalloys\/naval-propeller-shaft-liners\/\" \/>\n<meta property=\"og:site_name\" content=\"Spun Alloys\" \/>\n<meta property=\"article:modified_time\" content=\"2025-05-09T12:31:47+00:00\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\\\/\\\/westleygroup.co.uk\\\/spunalloys\\\/naval-propeller-shaft-liners\\\/\",\"url\":\"https:\\\/\\\/westleygroup.co.uk\\\/spunalloys\\\/naval-propeller-shaft-liners\\\/\",\"name\":\"Naval Propeller Shaft Liners - Spun Alloys\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/westleygroup.co.uk\\\/spunalloys\\\/#website\"},\"datePublished\":\"2025-04-14T14:56:08+00:00\",\"dateModified\":\"2025-05-09T12:31:47+00:00\",\"breadcrumb\":{\"@id\":\"https:\\\/\\\/westleygroup.co.uk\\\/spunalloys\\\/naval-propeller-shaft-liners\\\/#breadcrumb\"},\"inLanguage\":\"en-GB\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\\\/\\\/westleygroup.co.uk\\\/spunalloys\\\/naval-propeller-shaft-liners\\\/\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\\\/\\\/westleygroup.co.uk\\\/spunalloys\\\/naval-propeller-shaft-liners\\\/#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\\\/\\\/westleygroup.co.uk\\\/spunalloys\\\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Products &amp;
