The critical parameter is bore-to-OD concentricity \u2014 any eccentricity between bore and OD adds directly to the shaft runout of the assembly. HXC achieves \u00b10.003 mm concentricity by grinding the OD from the finished bore as datum in one setup.<\/div><\/div>\n          <div class=\"hxc-faq-item\"><button aria-expanded=\"false\" class=\"hxc-faq-q\" onclick=\"hxcFaq(this)\">What is the difference between an adapter sleeve and a reduction sleeve?<span class=\"hxc-faq-icon\">+<\/span><\/button><div class=\"hxc-faq-body\">An <strong>adapter sleeve<\/strong> converts a shaft OD to a different housing bore \u2014 for example, mounting a \u00d840 mm bearing onto a \u00d835 mm shaft. A <strong>reduction sleeve<\/strong> (reducer bushing) converts a motor shaft to a smaller coupling bore. Both use the same manufacturing approach but the fit directions differ: the adapter sleeve has an interference OD and clearance bore; the reduction sleeve has a clearance OD and clamped bore. HXC makes both.<\/div><\/div>\n          <div class=\"hxc-faq-item\"><button aria-expanded=\"false\" class=\"hxc-faq-q\" onclick=\"hxcFaq(this)\">What tolerance is needed for adapter sleeve bearing fits?<span class=\"hxc-faq-icon\">+<\/span><\/button><div class=\"hxc-faq-body\">The adapter sleeve OD fits into the bearing bore with <strong>p5 or r5 interference<\/strong> (same as a direct shaft-to-bearing fit) \u2014 the sleeve transmits radial load from the shaft to the bearing. The sleeve bore fits the shaft with <strong>H7\/h6 clearance<\/strong> (fixed by set-screw or locking nut). If concentricity between sleeve OD and bore is poor, the bearing runs eccentric on the shaft \u2014 causing vibration and reduced bearing life.<\/div><\/div>\n          <div class=\"hxc-faq-item\"><button aria-expanded=\"false\" class=\"hxc-faq-q\" onclick=\"hxcFaq(this)\">Why is bore honing important for sleeves?<span class=\"hxc-faq-icon\">+<\/span><\/button><div class=\"hxc-faq-body\">Internal grinding leaves a subtle three-lobe or five-lobe pattern from the grinding wheel contact. For a sleeve that runs directly on a shaft or carries a bearing in the bore, this lobing causes uneven contact and localised wear. <strong>Honing<\/strong> removes the lobing, producing a true-round bore (roundness \u2264 0.002 mm) with a cross-hatch finish that retains lubricant. HXC hones sleeve bores to IT4\u2013IT5 on precision orders.<\/div><\/div>\n        <\/div>\n        <div>\n          <div class=\"hxc-faq-item\"><button aria-expanded=\"false\" class=\"hxc-faq-q\" onclick=\"hxcFaq(this)\">What is the lead time?<span class=\"hxc-faq-icon\">+<\/span><\/button><div class=\"hxc-faq-body\">Prototype (1\u20135 pcs, turned + ground + honed): 4\u20137 days.
