Fafnir 7405W, a single row angular contact ball bearing built by The Timken Company. Bore Diameter: 25 mm. Outside Diameter: 80 mm. Overall Width: 21 mm. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Rolling Elements: Ball. Series: 7400. Base Number: 7405. Precision Class: ABEC 1 / P0. Internal Clearance: CN. Cage Type: One-piece, ball-guided. Item Weight: 0.925 kg (2.04 lb).
7400 — Fafnir heavy single-row angular contact series. Its 25 x 80 x 21 mm envelope is dimensionally interchangeable with the 200-series deep groove ball bearings.
05 — bore code. Bore code multiplied by five gives the bore in millimetres: 25 mm.
W — maximum-capacity angular contact execution with a low outer ring shoulder, which admits a fuller ball complement and raises radial capacity.
No clearance suffix — normal internal clearance, CN.
Dynamic Load Rating: 53,300 N. Static Load Rating: 25,900 N. Limiting Speed: 3,800 rpm grease; 5,700 rpm oil.
A single row angular contact bearing takes thrust in one direction only, and the low outer shoulder of the W execution is what lets the extra balls into the raceway. The result is a bearing that carries a heavy combined radial and one-way thrust load in a 21 mm width.
Precision Class: ABEC 1 / P0 — standard tolerance class, the general-purpose grade for pumps, gearboxes and industrial shafting.
Item Weight: 0.925 kg (2.04 lb).
Maximum shaft fillet radius: 1.5 mm. Shaft backing shoulder diameter: 34.00 mm. Housing backing shoulder diameter: 71.10 mm.
Straight bore, so the bearing mounts directly on a cylindrical shaft seat. Thrust is taken through the high shoulder, so the bearing is fitted with the high-shoulder face toward the thrust load.
Unit Quantity: 1 Pc. One single row bearing, open on both faces.
