Single Row Tapered Roller Bearing 30226 Inner Ring: 130.000mm Outer Ring: 230.000mm Width: 43.750mm Width of Inner Ring: 40.000mm Width of Outer Ring: 34.000mm Chamfer of Inner Ring: 4mm Chamfer of Outer Ring: 3mm Basic Dynamic Load Rating: 387KN Basic Static Load Rating: 539KN Limited Speed (rpm): 1620(grease)/2200(oil) Gross Weight: 7.02kg Single row tapered roller bearing can support a combined radial and axial load. If either a radial load or bi-directional axial load is to be carried, a pair of bearings must be used in a "face-to-face" or "back-to-back" mounting. The axial load carrying capacity of the bearings is largely determined by the contact angle. If the contact angle is larger, then the axial load carrying capacity is higher and vice versa. During equipment assembly, single row bearings can be set to the required clearance (endplay) or preload condition to optimize performance.
