NACHI is a Japanese precision bearing manufacturer, part of the NACHI-Fujikoshi Corporation, supplying deep groove ball bearings, cylindrical roller bearings, spherical roller bearings, angular contact ball bearings, and thrust bearings to engineering, manufacturing, and maintenance operations across Australia. NACHI angular contact ball bearings carry combined radial and axial loads at high speeds, and are used in pairs or sets in machine tool spindles, pumps, and precision equipment. Where this product is used NACHI angular contact ball bearing products are used across electric motors, industrial gearboxes, pumps, conveyors, and heavy engineering equipment. Machine tool spindles, pumps, and precision equipment carrying combined radial and axial loads. High-speed applications requiring stiff, precise running with controlled axial preload. Back-to-back or face-to-face paired arrangements in gearboxes and rotating equipment. Key specifications Refer to the product title for bore, outer diameter, width, and configuration details. Selecting the right option Select single-row (7000, 7200, 7300 series) for paired arrangements or double-row (5200, 5300) for combined loads in a single unit. Contact angle affects the axial to radial load ratio — B suffix indicates a 40° contact angle for higher axial capacity. Confirm the arrangement (back-to-back, face-to-face, or tandem) before ordering matched sets.
