NSK HR32004XJ single-row tapered roller bearings supplied as a back-to-back matched pair, each a complete cone and cup. Bore Diameter: 20 mm. Outside Diameter: 42 mm. Total Width T: 15 mm. Inner ring width B: 15 mm. Outer ring width C: 12 mm. Precision Class: RBEC 5 / P5. Rolling Elements: Tapered Roller. Number Of Rows: 1 per bearing. Bore Type: Straight. Bearing Material: Bearing steel.
HR — NSK high-capacity uprate. More and longer rollers inside the same boundary dimensions than the plain 32004X.
32004 — ISO 320-series tapered roller bearing, 20 x 42 x 15 mm.
X — boundary dimensions updated to the current ISO standard.
J — pressed steel cage.
P5 — ISO class 5, RBEC 5.
DB — duplex back-to-back. Two bearings ground as a matched set with their load lines diverging outward.
Dynamic Load Rating: 30,500 N (6,857 lbf). Static Load Rating: 27,400 N (6,160 lbf). Both ratings are per bearing.
Limiting Speed: 9,000 rpm grease; 12,000 rpm oil. Jet lubrication raises the ceiling to 17,000 rpm. Lubricant: grease or oil.
Cage Material: Pressed steel. Item Weight: 0.097 kg (0.21 lb) per bearing.
Calculation factors: e 0.37, Y 1.6, Y0 0.88. A tapered roller bearing takes combined radial and one-direction axial load; the back-to-back pair takes axial load in both directions and carries moment load across the spread between the two load lines.
Effective load centre a: 10.6 mm. Shaft abutment diameter da min: 28 mm. Housing abutment diameter Da: 35 to 37 mm. Housing abutment diameter Db min: 40 mm. Maximum shaft fillet radius ra: 0.6 mm.
Unit Quantity: 2 Pcs. Mounting Arrangement: back-to-back (DB) matched pair.
Timken 32004X, SKF 32004 X, FAG 32004-X, NTN 4T-32004X and Koyo 32004JR are standard single 32004X-size bearings with the same 20 x 42 x 15 mm boundary dimensions. The HR execution carries higher load ratings than a plain 32004X, so those parts match on size, not capacity, and none is a matched P5 pair.
