MPN: 4T-30211
Stock #: 0226-00192
The NTN 4T-30211 is a single row tapered roller bearing with a 55 mm bore, 100 mm outside diameter, and 22.75 mm overall width. The 4T prefix designates NTN's case carburized steel construction, engineered to deliver improved fatigue life and shock load resistance compared to standard through hardened tapered roller bearings. Internal dimensions include a cone width (B) of 21 mm and a cup width (C) of 18 mm. The bearing is supplied as a complete assembly consisting of an inner ring (cone) with roller and cage assembly, plus a separable outer ring (cup), allowing independent mounting of each component during shaft and housing assembly. Rated dynamic load capacity is 93 kN with a static load capacity of 111 kN. Limiting speed is 3,600 RPM under grease lubrication and 4,900 RPM under oil lubrication. The cage is sheet steel and tolerance class is P0/PN2 (ABEC 1). Operating temperature range is 40 to 120 degrees C. The tapered geometry supports combined radial and axial loads in one direction and is commonly used in mirror image pairs for two direction axial load capability. Typical applications include gearboxes, wheel hubs, industrial drive shafts, pumps, conveyors, and general rotating equipment requiring high radial and thrust capacity. Box is marked with NTN part number 4T-30211[J100], catalog reference 30211, UPC 4547359003239, and date code 12/16/14. Supplied in original NTN factory packaging.
