Fafnir 314NPP single-row deep groove ball bearing, built by The Timken Company. Bore Diameter: 70 mm. Outside Diameter: 150 mm. Overall Width: 35 mm. Series: 300. Base Number: 314. Closure Type: Contact seals both sides. Bore Type: Straight. Number Of Rows: 1. Rolling Elements: Ball. Bearing Material: Chrome steel. Lubricant: Grease.
314 — Fafnir 300 medium series, bore code 14, giving a 70 mm bore in a 150 mm outside diameter.
N — snap-ring groove machined into the outer ring, which accepts a housing retaining ring for axial location.
PP — contact seals both sides. Rubber land-riding lips run against the inner ring, holding grease in and contamination out.
Dynamic Load Rating: 115,500 N. Static Load Rating: 68,000 N. Limiting Speed: 1,500 rpm grease; 3,182 rpm oil. Precision Class: ABEC 1 / P0. Internal Clearance: CN.
The 115,500 N dynamic rating is the load at which the bearing reaches one million revolutions of calculated fatigue life. The 68,000 N static rating is the load that produces the permissible permanent deformation at the raceway contact, and it governs shock and standstill duty. Contact seals trade speed for sealing: the 1,500 rpm grease figure reflects lip drag, while the 3,182 rpm oil figure applies to the same ring set in a flooded or circulating oil feed. CN clearance is the standard radial internal clearance, suited to normal interference fits and moderate temperature rise across the rings.
Maximum shaft fillet radius: 2.11 mm. Shaft backing shoulder diameter: 81.99 mm. Housing backing shoulder diameter: 137.90 mm. Outer ring to-clear radius: 2.11 mm.
Unit Quantity: 1 Pc. One complete sealed bearing per unit.
The 314NPP occupies the 70 x 150 x 35 mm 6314-2RS envelope, so a standard-class sealed 6314 mounts on the same shaft seat and in the same housing bore. Those standard parts have a plain outer ring; the 314NPP adds the snap-ring groove, and the Cross-Reference attributes label each equivalent accordingly.
