The fastest starting point is the machine make, model, serial number, bearing part number, and photos of the identification marks. This route helps distinguish machines that share a model family but use different bearings by production year or configuration.<\/p>\n<p>An approved bearing or equipment drawing provides a stronger dimensional basis. Send the outside and inside diameters, overall height, mounting-hole pattern, locating features, gear data, rotating ring, seals, lubrication ports, and required clearance or preload. Mark the drawing revision so the quote and the manufactured bearing refer to the same interface.<\/p>\n<p>An old sample can support reverse engineering when the original records are unavailable. Pair it with measurements from the machine structure and any historical drawings because wear, distortion, corrosion, or previous repair work can alter the removed part.<\/p>\n<p><strong>Matching routes<\/strong><\/p>\n<div class=\"scroll\" tabindex=\"0\" role=\"region\" aria-label=\"Scrollable table\">\n<table>\n<thead>\n<tr>\n<th scope=\"col\">What you have<\/th>\n<th scope=\"col\">What to send<\/th>\n<th scope=\"col\">What SWBTEC can establish first<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Machine information<\/td>\n<td>Make, model, serial number, application, current part number, nameplate and bearing photos<\/td>\n<td>A candidate replacement and the remaining checks needed<\/td>\n<\/tr>\n<tr>\n<td>Controlled drawing<\/td>\n<td>Dimensioned drawing, revision, tolerances, material and gear requirements<\/td>\n<td>Interface compatibility and a technical review scope<\/td>\n<\/tr>\n<tr>\n<td>Old bearing or field measurements<\/td>\n<td>Old sample, measured dimensions, equipment-side hole pattern, pinion data and operating history<\/td>\n<td>A replacement drawing for review before production<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p><a class=\"button\" href=\"#coreshangye-quote\" data-product=\"bearing slewing ring\">Request a Replacement Review<\/a><\/div>\n<\/section>\n<section class=\"coreshangye-keyword-module palette-1\" id=\"matching-data\" aria-labelledby=\"matching-data-title\">\n<div class=\"wrap\">\n<h2 id=\"matching-data-title\"><span class=\"ez-toc-section\" id=\"Data_Needed_to_Match_a_Slewing_Ring_Bearing\"><\/span>Data Needed to Match a Slewing Ring Bearing<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The selection starts with a load case, motion profile, interface, and service environment.

A small change in bearing height can shift the pinion contact position, while a hole-pattern or pilot-fit difference can prevent assembly or transfer load incorrectly. The rotating-ring choice also determines how the bearing connects to the drive and where cables, hoses, and lubrication points move.<\/p>\n<p>The support structure affects bearing performance after installation. Record the mounting-face flatness, stiffness, plate thickness, weld locations, pilot fits, coating thickness, and fastener access. The mating surfaces must be clean and flat, and the connection must provide uniform clamping. Installation bolt grade, preload method, and tightening sequence belong in the approved installation plan.<\/p>\n<p>A geared replacement must preserve the intended mesh across the full rotation. Gear geometry establishes the nominal center distance and tooth engagement; bearing and pinion runout then change the working backlash around the circumference. The approved installation method should set backlash at the marked maximum-runout position and verify the contact pattern before the machine returns to service.<\/p>\n<p><a class=\"button\" href=\"#coreshangye-quote\" data-product=\"bearing slewing ring\">Send an Interface Drawing<\/a><\/div>\n<\/section>\n<section class=\"coreshangye-keyword-module palette-0\" id=\"load-and-life\" aria-labelledby=\"load-and-life-title\">\n<div class=\"wrap\">\n<h2 id=\"load-and-life-title\"><span class=\"ez-toc-section\" id=\"Match_Loads_Motion_and_Service_Life\"><\/span>Match Loads, Motion, and Service Life<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Static selection checks the rolling raceway and the bolted connection against the same load cases. A bearing is not confirmed when only one catalog load value passes. The adjacent structure must also remain stiff and flat enough to distribute load around the rings and bolts.<\/p>\n<p>Service-life work uses the actual motion and load spectrum. Slow full rotation, continuous rotation, and small-angle oscillation place different demands on the raceway and lubricant. Starts, stops, reversals, shock events, contamination, corrosion, and lubrication intervals can control field life even when the maximum static condition is acceptable.<\/p>\n<p>For geared bearings, the review also covers tooth contact capacity, tooth-root strength, pinion load, backlash, lubrication, and drive events. Multiple pinions require a load-sharing assessment because structure deflection and installation variation can prevent equal torque distribution.<\/p>\n<p><strong>Engineering output to request:<\/strong> selected bearing and drawing revision \u00b7 controlling load cases \u00b7 raceway and bolt review \u00b7 gear review when applicable \u00b7 life basis \u00b7 installation assumptions \u00b7 verification plan<\/p>\n<p><a class=\"button\" href=\"#coreshangye-quote\" data-product=\"bearing slewing ring\">Request an Application Review<\/a><\/div>\n<\/section>\n<section class=\"coreshangye-keyword-module palette-1\" id=\"drawing-and-inspection\" aria-labelledby=\"drawing-and-inspection-title\">\n<div class=\"wrap\">\n<h2 id=\"drawing-and-inspection-title\"><span class=\"ez-toc-section\" id=\"Freeze_the_Drawing_Then_Verify_the_Built_Bearing\"><\/span>Freeze the Drawing, Then Verify the Built Bearing<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Production should begin from an approved drawing and a frozen technical specification.
