Always use a clean set of digital calipers rather than a tape measure or ruler.<\/p>\n<ul>\n<li><strong>Zero the caliper:<\/strong> Close the jaws completely and zero out your digital calipers.<\/li>\n<li><strong>Use the top jaws:<\/strong> Insert the upper inside jaws directly into the bearing bore.<\/li>\n<li><strong>Measure the widest point:<\/strong> Open the jaws until they touch the inner ring walls firmly, keeping the tool perpendicular to the bearing face.<\/li>\n<li><strong>Rotate and re-check:<\/strong> Take two or three readings at different angles to ensure the bore is not warped or ovalized.<\/li>\n<\/ul>\n<h3>Checking Outer Diameter and Total Width<\/h3>\n<p>Once you have the bore, you need the <strong>bearing outer diameter (OD)<\/strong> and total <strong>bearing width thickness<\/strong>.<\/p>\n<ul>\n<li><strong>Outer Diameter (OD):<\/strong> Place the main outside jaws of your caliper across the outer steel ring. Measure across the dead center for maximum width.<\/li>\n<li><strong>Total Width:<\/strong> Clamp the jaws across the flat outer faces of the bearing rings. <\/li>\n<li><strong>Ignore seal protrusion:<\/strong> On quality <strong>2RS rubber sealed bearings<\/strong>, the seal sits flush with or slightly below the steel surface. Measure the metal rings directly rather than squeezing the rubber lip.<\/li>\n<\/ul>\n<h3>Accounting for Wear and Surface Damage<\/h3>\n<p>Used machinery parts rarely measure like brand-new factory components. Shaft friction, rust, or heavy loads often alter the metal.<\/p>\n<ul>\n<li><strong>Clean before measuring:<\/strong> Wipe off grease, road grime, or rust spots with a rag so your calipers sit flat against clean steel.<\/li>\n<li><strong>Spotting shaft wear:<\/strong> If your bore reads slightly smaller or larger than expected (e.g., 14.94 mm instead of 15.00 mm), account for metal wear on the shaft or bearing ring.<\/li>\n<li><strong>Round to standard ISO metric sizes:<\/strong> Standard <strong>single row radial<\/strong> bearings follow strict metric steps. If your caliper reads 24.97 mm <strong>outer diameter<\/strong> and 14.98 mm <strong>inner diameter<\/strong>, you are looking at a standard 25 mm OD by 15 mm <strong>bore diameter<\/strong>.
