RHP 7203BETN single-row angular contact ball bearing: 17 mm bore, 40 mm outside diameter, 12 mm width, 40° contact angle, high-capacity B-series design with a polyamide cage, open. Unit Quantity: 1 Pc. Single bearing, takes thrust in one direction only.
7203 — ISO 72 dimension series, bore code 03. Bore 17 mm, outside diameter 40 mm, width 12 mm.
B — the 40° contact angle of the standard-precision ISO B range.
E — high load capacity execution. A larger ball complement on the same envelope raises both load ratings over the plain 7203B.
TN — moulded polyamide cage.
Bore Diameter: 17 mm. Outside Diameter: 40 mm. Overall Width: 12 mm. Contact Angle: 40°. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Cage Material: Polyamide. Cage Type: Moulded, ball-guided. Dynamic Load Rating: 12,100 N. Static Load Rating: 6,100 N. Limiting Speed: 16,000 rpm grease; 22,000 rpm oil. Precision Class: ABEC 1 / P0. Internal Clearance: CN. Series: 7200. Item Weight: 0.065 kg (0.14 lb).
A single row of balls runs on raceways offset so that the line of contact sits at 40° to the radial plane: high thrust load in one direction, smaller radial load.
Effective load centre a: 18.2 mm from the bearing face. Chamfer dimension r min: 0.6 mm. Shaft abutment diameter da: 22 mm min. Housing abutment diameter Da: 35 mm max. Maximum fillet radius on the shaft or housing ra: 0.6 mm.
