Exact compatibility should not be promised until that relationship has been reviewed. In some cases the safer project may be a new matched pair rather than one replacement member.<\/p>\n<\/div>\n<\/section>\n<section class=\"ep-section\">\n<div class=\"ep-container\">\n<h2>Packing a physical sample<\/h2>\n<p>Protect teeth and datum surfaces from further damage. Identify which marks are existing service damage and which were added for orientation. Include a simple packing note that links each sample to the drawing\/reference used in the RFQ so multiple parts are not mixed during review.<\/p>\n<\/div>\n<\/section>\n<section class=\"ep-section\">\n<div class=\"ep-container\">\n<h2>Before shipping a sample for review<\/h2>\n<p>Clean only enough to expose useful surfaces and markings; do not grind or polish away wear evidence. Protect the teeth, bearing seats and datum faces during packing. If two members belong together, tag them as one pair and include an orientation note. If several similar gears are shipped, assign each sample a unique reference that matches the RFQ and photos.<\/p>\n<p>Include a short \u201cknown \/ unknown\u201d sheet. It should state which values come from a drawing, which were measured from the worn sample, and which still need review. This prevents a bench measurement from being mistaken for an original design value.<\/p>\n<\/div>\n<\/section>\n<section class=\"ep-section\">\n<div class=\"ep-container\">\n<h2>Questions buyers often ask<\/h2>\n<div class=\"ep-accordion\">\n<details>\n<summary>Can one worn gear be enough to make a replacement?<\/summary>\n<p>Sometimes there is enough reliable information, but it should not be assumed. The mate, housing measurements or legacy data can be essential for reconstructing the original pair.<\/p>\n<\/details>\n<details>\n<summary>Should I replace both members?<\/summary>\n<p>That depends on the condition and how well the remaining mate is defined. A new matched pair may reduce uncertainty when the existing mate is badly worn or undocumented.<\/p>\n<\/details>\n<details>\n<summary>Can a part number identify the gear exactly?<\/summary>\n<p>It is useful evidence, but revisions and field changes can exist. Combine the reference with current measurements and the mating relationship.<\/p>\n<\/details>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"ep-section\"><div class=\"ep-container\"><div class=\"ep-body-cta\"><div><span class=\"ep-eyebrow\">Request a quote<\/span><h2>Send the gear pair, drawing and duty in one RFQ.<\/h2><p>The more clearly the mating relationship and assembly datums are defined, the faster the configuration can be reviewed.<\/p><div class=\"ep-procurement-note\"><h3>Ordering & delivery guidance<\/h3><p>MOQ is flexible by product type, manufacturing route and total order value. Suitable new projects may request 1\u20135 sample pieces at sample pricing. Mixed models can be combined when the order total reaches approximately USD 1,500. Orders of 1\u20132 pieces can be reviewed, although unit cost is normally higher.<\/p><p>Typical planning windows are 10\u201325 working days for standard parts, 20\u201345 working days for customized components and 45\u2013120 working days for project-type equipment or assemblies. EXW, FOB, CIF and DAP are commonly supported; FCA, CFR, CPT, CIP and DDP can be discussed for the shipment.<\/p><\/div><\/div><a class=\"ep-btn\" href=\"#rfq-form\">Send RFQ<\/a><\/div><\/div><\/section>","protected":false},"excerpt":{"rendered":"<p>A replacement spiral bevel gear identification checklist covering the mating gear, housing datums, samples, drawings and wear.<\/p>","protected":false},"author":1,"featured_media":467,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-497","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-spiralgears"],"_links":{"self":[{"href":"https:\/\/spiralgears.top\/pl\/wp-json\/wp\/v2\/posts\/497","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/spiralgears.top\/pl\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/spiralgears.top\/pl\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/spiralgears.top\/pl\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/spiralgears.top\/pl\/wp-json\/wp\/v2\/comments?post=497"}],"version-history":[{"count":2,"href":"https:\/\/spiralgears.top\/pl\/wp-json\/wp\/v2\/posts\/497\/revisions"}],"predecessor-version":[{"id":580,"href":"https:\/\/spiralgears.top\/pl\/wp-json\/wp\/v2\/posts\/497\/revisions\/580"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/spiralgears.top\/pl\/wp-json\/wp\/v2\/media\/467"}],"wp:attachment":[{"href":"https:\/\/spiralgears.top\/pl\/wp-json\/wp\/v2\/media?parent=497"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/spiralgears.top\/pl\/wp-json\/wp\/v2\/categories?post=497"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/spiralgears.top\/pl\/wp-json\/wp\/v2\/tags?post=497"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
