Supplied as a factory-matched pair, it delivers the correct running clearance straight out of the box — no mixing and matching of loose races. SET52 is the standard replacement for the \u003cstrong\u003eA52\u003c\/strong\u003e interchange and is widely used in trailer hubs, agricultural equipment, and light-duty industrial shafting.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet number:\u003c\/strong\u003e SET52\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCone (inner race):\u003c\/strong\u003e 25580\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCup (outer race):\u003c\/strong\u003e 25520\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore:\u003c\/strong\u003e 1.750 in (44.45 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside diameter:\u003c\/strong\u003e 3.265 in (82.93 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAssembled width:\u003c\/strong\u003e 0.9375 in (23.81 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e TS single-row tapered roller bearing, imperial series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Timken\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInterchange \u0026amp; cross-reference\u003c\/h3\u003e\n\u003cp\u003eCommonly cross-referenced as \u003cstrong\u003eA52\u003c\/strong\u003e, \u003cstrong\u003eSET 52\u003c\/strong\u003e, \u003cstrong\u003e25580\/25520\u003c\/strong\u003e, and \u003cstrong\u003e25580-25520\u003c\/strong\u003e.
