Timken 05079 Tapered Roller Bearing Cone

The Timken 05079 is a single-row tapered roller bearing cone engineered to carry a combination of radial and axial (thrust) loads in compact rotating equipment. It is designed for use in automotive wheel hubs, light-duty trailers, agricultural machinery, industrial gearboxes, conveyors, and power transmission systems. The cone mates with Timken bearing cups 05185, 05185-B, and 05180D. Key specs include an inch-based bore of 0.7869 in (19.987 mm) and an inner ring width of 0.5662 in (14.381 mm); cage material is stamped steel and the unit weighs 0.56 lb (0.255 kg). Dynamic radial load ratings are C1 = 6,010 lbf (26,700 N) and C90 = 1,560 lbf (6,930 N), with a dynamic axial load rating Ca90 of 952 lbf (4,230 N) and a static radial load rating C0 of 5,720 lbf (25,400 N). Other details include a maximum shaft fillet radius of 0.060 in (1.5 mm), shaft backing shoulder diameters frontface da = 0.94 in (24 mm) and backface db = 1.04 in (26.5 mm), and an effective center location of −0.16 in (−4.1 mm). The geometry factor Cg is 0.0448 and the K factor is 1.64.
