Product Description

What this part is: Timken HH914412 inch tapered roller bearing single cup. Cup only. Manufacturer: Timken. Manufacturer Part Number: HH914412. Cup Part Number: HH914412. Base Number: HH914412. Series: HH914400. Bearing Type: Tapered Roller Bearing Single Cup. Number of Rows: 1. Rolling Elements: Tapered Rollers. Design Units: Inch. Outside Diameter: 7.0000 in (177.800 mm). Outer Ring Width: 1.4688 in (37.308 mm). Bearing Material: Case-Carburized Steel. Precision Class: Not specified. Item Weight: 14.70 lb (6.7 kg). Unit Quantity: 1 Pc. The matching cones are the Timken HH914449 and HH914447. Decoding the designation: HH914412 is the cup number in Timken’s HH914400 inch series. The HH prefix marks a Timken series designation rather than a design suffix. Searchable forms of the number are HH914412, HH-914412, HH 914412 and 914412. What these specs mean in practice: e Factor: 0.80. Y Factor: 0.75. Geometry Factor Cg: 0.104. The e factor of 0.80 is the load-ratio threshold at which the thrust term enters the equivalent-load calculation, and it is high for an inch taper, which reflects a shallow raceway angle weighted toward radial load. The Y factor of 0.75 converts a thrust component into an equivalent radial load once that threshold is passed. A cup is the outer race alone: the raceway is ground into its bore, and the roller path angle is cut to match its mating cone. Harmonization Code: 8482.20.00. Mounting dimensions: Maximum Housing Fillet Radius: 0.130 in (3.30 mm). Housing Backing Shoulder Diameter, frontface (Da): 6.54 in (166.12 mm). Housing Backing Shoulder Diameter, backface (Db): 5.75 in (146.05 mm). These are the figures that decide whether a given housing step and fillet will clear the cup corners. Quantity and configuration: Unit Quantity: 1 Pc. Cup only: the outer ring on its own, with the tapered raceway ground into the bore. Cone and cup mating: The matching cones are the Timken HH914449 and HH914447, giving the TS single-row assemblies HH914449/HH914412 and HH914447/HH914412. Each cone carries the inner ring, the tapered roller set and the cage. Interchange guidance: The HH914412-2 is the same cup held to Class 2 precision and is a separate Timken part number with a tighter running-accuracy tolerance. It is a related execution rather than the same item.
