FAG3206BTVHP6Double Row Angular Contact Ball Bearing – 30 mm Bore, 62 mm OD, 23.8 mm Width, 30° Contact Angle, Open, ABEC 3 / P6

Product Description

What this part is

FAG 3206-B-TVH-P6 double-row angular contact ball bearing. Two ball rows sit back to back in one pair of rings, so a single bearing takes radial load plus thrust in both directions and resists tilting moments without a second bearing seat. Bore Diameter: 30 mm. Outside Diameter: 62 mm. Overall Width: 23.8 mm (0.9375 in). Contact Angle: 30°. Dynamic Load Rating: 31,000 N. Static Load Rating: 22,200 N. Limiting Speed: 11,900 rpm. Reference Speed: 11,100 rpm. Precision Class: ABEC 3 / P6. Cage Material: Polyamide. Rolling Elements: Ball. Number Of Rows: 2. Bore Type: Straight. Closure Type: Open. Item Weight: 0.278 kg (0.61 lb). Bearing Material: Chrome steel. Unit Quantity: 1 Pc. Series: 32. Base Number: 3206.

Decoding the designation

32 — ISO double-row angular contact ball bearing series, dimension series 32.

06 — bore code; 30 mm bore.

B — the 30° double-row design generation.

TVH — glass-fibre reinforced polyamide cage, one piece. A different material from the TPA and T phenolic codes used on the FAG spindle range.

P6 — tolerance class P6, equivalent to ABEC 3. One step above standard.

5206 — the older ISO designation for the same bearing, still carried on many cartons and parts lists.

What these specs mean in practice

Contact Angle: 30°. That is a steep angle for a ball bearing and it is what gives the double-row 32 series its thrust capacity in both directions. The distance between the apexes of the two pressure cones is 36.4 mm, which is the effective bearing spread and the figure that sets moment stiffness.

Dynamic Load Rating: 31,000 N. Static Load Rating: 22,200 N. Fatigue load limit: 1,540 N.

Limiting Speed: 11,900 rpm is the mechanical ceiling for the open execution. Reference Speed: 11,100 rpm is the thermally referenced figure.

Precision Class: ABEC 3 / P6 tightens running accuracy and bore and outside diameter tolerance over a standard bearing, which matters on a shaft that has to hold position under reversing thrust.

Operating temperature range: −30 °C to 120 °C.

Interchange guidance

3206 and 5206 are the current and superseded ISO numbers for the same 30 x 62 x 23.8 mm double-row angular contact ball bearing, and every major maker builds it to that envelope with a 30° contact angle. The cross-references below are direct interchanges in the open execution; cage material and precision class vary by maker. Designation variants: 3206B.TVH.P6, 3206-B-TVH-P6, 3206BTVHP6, 3206B, 3206-BD-TVH, 3206-BD-XL-TVH, 5206.
