The Timken Company 80TP134 Thrust Cylindrical Roller Bearing

The Timken 80TP134 thrust cylindrical roller bearing is a separable, high-capacity unit designed to support exceptionally high axial loads with low friction and excellent axial stiffness in heavy‑duty industrial equipment. This TP Series bearing (inch design) has an 8.0000 in bore (203.20 mm), an outer diameter of 12.0000 in (304.80 mm), and a width of 3.0000 in (76.20 mm); it also lists a large bore diameter d1 of 8.094 in (205.58 mm) and a small outside diameter D1 of 11.906 in (302.42 mm), with shaft shoulder diameter H of 8.500 in (215.90 mm) and housing shoulder diameter E of 11.500 in (292.10 mm). The fillet chamfer radius is 0.063 in (1.60 mm). It provides a dynamic axial load rating (Ca90) of 254,000 lbf (1,100,000 N) and a static axial load rating (Ca0) of 698,300 lbf (3,100,000 N), with a limiting speed of 1,260 rpm. Weight is 45.32 lb (20.56 kg). Typical applications include rolling mills, industrial gearboxes, marine propulsion systems, mining equipment, vertical shaft machinery, and heavy‑duty presses, where substantial thrust loading and precise axial positioning are required. The design supports straightforward installation and maintenance due to its separable construction, and common replacements include SKF 80TP134, NTN 80TP134, and KOYO 80TP134.
