FAG 21310-E1-K-TVPB-C3 double-row spherical roller bearing. Bore Diameter: 50 mm. Outside Diameter: 110 mm. Overall Width: 27 mm. Series: 213. Base Number: 21310. Number Of Rows: 2. Rolling Elements: Spherical Roller. Bore Type: Tapered 1:12. Closure Type: Open. Bearing Material: Chrome steel. Item Weight: 0.85 kg (1.86 lb). GTIN: 4026677807434.
213 — spherical roller bearing dimension series 213 to DIN 635-2, two rows of barrel rollers on one sphered outer raceway.
10 — bore code, 50 mm bore.
E1 — reinforced internal design with a larger roller complement and higher load ratings.
K — tapered bore, 1:12 taper.
TVPB — glass-fibre reinforced polyamide cage.
C3 — radial internal clearance greater than normal.
Dynamic Load Rating: 140,000 N. Static Load Rating: 146,000 N. Limiting Speed: 8,500 rpm. Reference Speed: 6,000 rpm. Internal Clearance: C3. Cage Material: Polyamide. Cage Type: Solid, one-piece. Precision Class: RBEC 1 / P0.
The sphered outer raceway lets both roller rows swivel as a unit, so the bearing accommodates static misalignment and shaft deflection while carrying heavy radial load, and it takes thrust in both directions. On this bearing class the static rating sits above the dynamic rating, which is normal for a double-row spherical roller: the large contact area under a stationary load raises the permissible static figure.
Unit Quantity: 1 Pc. Single bearing, open on both faces, 1:12 tapered bore.
Bore Type: Tapered 1:12. The 50 mm tapered bore seats on a matching tapered shaft journal, or on an H310 adapter sleeve when the shaft is plain. The H310 takes a 45 mm shaft seat and its tapered outside diameter is 50 mm, matching this bore. Driving the bearing further up the taper reduces the radial internal clearance, which is how the C3 starting clearance is consumed to set the running fit.
50 x 110 x 27 mm on a 1:12 tapered bore is the ISO boundary size for a 21310 K. The cross-reference fields list that envelope in the same double-row spherical roller construction; the NSK E4 and Timken and Torrington W33 entries add an outer-ring lubrication groove that this execution does not carry, and FAG 21310-E1-XL-K-TVPB-C3 is the X-life execution with higher ratings.
