The \"A\" design variant features specific internal geometry; the \"JS3\" suffix denotes a controlled radial internal clearance falling within the C3 (greater than normal) range, manufactured to tighter tolerance; and the \"S1\" suffix indicates dimensional stabilization for sustained operation at elevated temperatures up to approximately 200°C.\u003c\/p\u003e\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eNeedle roller bearings deliver exceptionally high radial load capacity in a compact cross-section, making them essential where space is limited but radial loads are heavy. The included inner ring allows installation on shafts that have not been hardened or ground.\u003c\/p\u003e\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThis is a specialty bearing, NOT a standard NA4830 — verify the JS3.C3.S1 specification matches your application requirements.\u003c\/p\u003e\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSPECIFICATIONS\u003c\/p\u003e\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBore (inner diameter): 150 mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOuter diameter: 190 mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWidth: 40 mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBearing type: Machined needle roller with inner ring (NA series)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eInternal clearance: JS3 (controlled C3-range, tighter tolerance)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHeat stabilization: S1 (rated to approximately 200°C)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCage: Steel, machined\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOuter ring: Lubrication groove and oil hole standard\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBearing weight: Approximately 7 lbs (3.2 kg)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eCOMMON APPLICATIONS\u003c\/p\u003e\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThis bearing is used in heavy-duty industrial applications where high radial loads, compact cross-sections, and elevated operating temperatures coexist: heavy gearboxes and reducers, paper and steel mill machinery, hot-rolling equipment, automotive and truck transmissions in high-load configurations, agricultural and construction equipment, mining gearboxes, and high-temperature pump and compressor applications.\u003c\/p\u003e\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eCROSS-REFERENCES \/ SUPERSEDES\u003c\/p\u003e\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe JS3.C3.S1 specification crosses between FAG and Torrington (Timken) under the same designation.
