Timken HH221430 / HH221410D / HH221430XA two-row tapered roller bearing in the TDO (tapered double outer) configuration — two cones running in one double cup. Cone Bore: 3 in (76.2 mm). Outside Diameter: 7.5 in (190.5 mm). Outer Ring Width: 4.125 in (104.775 mm). Cone Inner Ring Width: 2.2650 in (57.531 mm) each. Number Of Rows: 2. Rolling Elements: Tapered rollers.
HH221430 — Timken inch tapered roller cone, 3 in bore, K factor 1.74.
D on HH221410D — double cup. One outer ring carries both raceways, so the two rows share a single housing seat.
TDO — tapered double outer. The two rows sit back to back inside the cup, which gives the widest effective bearing spread of the two-row tapered configurations.
Dynamic Load Rating per row (C1): 120,000 lbf (534,000 N). Dynamic Load Rating per row (C90): 31,100 lbf (138,000 N). Dynamic Axial Rating per row (Ca90): 17,800 lbf (79,300 N). Static Load Rating per row (C0): 156,000 lbf (692,000 N).
K Factor: 1.74. e Factor: 0.33. Y1 Factor: 2.02. Y2 Factor: 3. Two opposed rows in one cup take thrust in both directions, and the wide spread across the 4.125 in cup width is what lets a TDO carry overturning moments that a single row cannot.
Max Housing Fillet Radius: 0.06 in (1.5 mm). Housing Backing Shoulder Diameter, frontface (Da): 7.06 in (179.32 mm). Max Shaft Fillet Radius: 0.140 in (3.600 mm). Shaft Backing Shoulder Diameter, frontface (da): 3.74 in (95 mm). Shaft Backing Shoulder Diameter, backface (db): 3.98 in (101 mm). Cone Effective Center Location: -0.59 in (-15 mm), inside the cone backface. Cage Location relative to backface (Aa): 0.08 in (2 mm). Cage Location relative to frontface (Ab): 0.16 in (4.1 mm). Geometry Factor (Cg): 0.107. G1 Factor: 265.6. G2 Factor: 28.4.
Cone Weight: 39.7 lb (18.01 kg) each. Double Cup Weight: 32.65 lb (14.811 kg).
Unit Quantity: 3 Pcs — two cones and one double cup, marked HH221430, HH221430XA and HH221410D. A TDO mounts either fixed in the housing bore or free to float in it.
Searchable forms of the designation: HH221430/HH221410D, HH221430-HH221410D, HH 221430, HH221410D, HH221410-D, HH221430XA. The tapered single built on the same cone is the HH221430/HH221410. The companion TDO on the same double cup is the HH221438/HH221410D.
