Commonly installed in industrial gearboxes, transmissions, hydraulic equipment, machine tools, agricultural machinery, and power transmission systems where compact, high-load bearing arrangements are required. Maintenance teams, OEMs, and system integrators use this inner ring for equipment repair, bearing replacement, machine rebuilds, and drivetrain retrofits to provide a hardened, wear-resistant running surface for needle rollers. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"695\" data-end=\"712\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"713\" data-end=\"1236\"\u003eThe Torrington IR-242820 needle roller bearing inner ring is engineered for demanding industrial applications requiring a precision-ground raceway and high wear resistance. It is widely used with heavy-duty caged needle roller bearings in industrial gear reducers, conveyors, hydraulic systems, pumps, construction equipment, agricultural machinery, and other rotating equipment where a hardened shaft is impractical. It is commonly paired with HJ-283720 series needle roller bearings. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1238\" data-end=\"1267\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1268\" data-end=\"1918\"\u003e• Manufacturer: Torrington (now part of Timken)\u003cbr data-start=\"1315\" data-end=\"1318\"\u003e• Manufacturer Part Number (MPN): IR-242820\u003cbr data-start=\"1361\" data-end=\"1364\"\u003e• Product Type: Needle roller bearing inner ring\u003cbr data-start=\"1412\" data-end=\"1415\"\u003e• Series: IR Inch Series\u003cbr data-start=\"1439\" data-end=\"1442\"\u003e• Bore Diameter (ID): 1.5000 in (38.100 mm)\u003cbr data-start=\"1485\" data-end=\"1488\"\u003e• Outside Diameter (OD): 1.7500 in (44.450 mm)\u003cbr data-start=\"1534\" data-end=\"1537\"\u003e• Width: 1.2500 in (31.750 mm)\u003cbr data-start=\"1567\" data-end=\"1570\"\u003e• Material: Hardened high carbon chrome steel\u003cbr data-start=\"1615\" data-end=\"1618\"\u003e• Raceway: Precision-ground and hardened\u003cbr data-start=\"1658\" data-end=\"1661\"\u003e• Bearing Type: Separable inner ring for heavy-duty needle roller bearings\u003cbr data-start=\"1735\" data-end=\"1738\"\u003e• Compatible Bearing: HJ-283720 heavy-duty needle roller bearing\u003cbr data-start=\"1802\" data-end=\"1805\"\u003e• Minimum Chamfer Radius: 0.060 in (1.52 mm)\u003cbr data-start=\"1849\" data-end=\"1852\"\u003e• Weight: 0.095 kg (0.21 lb) \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"1920\" data-end=\"1944\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"1945\" data-end=\"2038\"\u003e• Timken IR-242820\u003cbr data-start=\"1963\" data-end=\"1966\"\u003e• Koyo IR-242820\u003cbr data-start=\"1982\" data-end=\"1985\"\u003e• INA PI 242820\u003c\/p\u003e","brand":"Timken","offers":[{"title":"New","offer_id":51714036465966,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_6d87055f-fd86-4a63-ad7d-3d7b40d6b351.jpg?v=1770414510","url":"https:\/\/plgautomation.com\/products\/torrington-ir-242820-needle-roller-bearing-inner-ring","provider":"PLG Automation ","version":"1.0","type":"link"}
