SKA 51114 is a single-direction grooved thrust ball bearing. Bore Diameter: 70 mm. Outside Diameter: 95 mm. Overall Width: 18 mm. Number Of Rows: 1. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Bearing Material: Chrome steel. Lubricant: Grease or oil. Series: 511. Base Number: 51114. Unit Quantity: 1 Pc.
511 — the single-direction thrust ball bearing series with flat seating faces, to DIN 711 / ISO 104.
14 — bore code 14, which is 70 mm.
The bearing takes pure axial load in one direction. Both raceway washers are grooved, so the ball set runs in a formed track rather than on a flat face, and that groove is what carries the thrust in an 18 mm stack height.
Flat outer faces on both washers, so the bearing seats against plain machined faces with no shoulder profile to match.
A thrust ball set is churning-limited at speed rather than load-limited, which is why oil lubrication lifts the speed ceiling well above a grease pack in the same envelope.
Shaft washer bore: 70 mm. Housing washer outside diameter: 95 mm. Assembly height: 18 mm. The two washers and the ball-and-cage assembly separate for fitting.
Unit Quantity: 1 Pc. One complete bearing: shaft washer, housing washer and one ball-and-cage assembly.
51114 is an interchangeable metric designation to DIN 711 / ISO 104, so any maker’s 51114 shares the 70 x 95 x 18 mm envelope and the single-direction grooved-washer construction.
Cross-Reference 1: SKF 51114. Cross-Reference 2: FAG 51114. Cross-Reference 3: NSK 51114. Cross-Reference 4: NTN 51114. Cross-Reference 5: Koyo 51114. Cross-Reference 6: INA 51114. Cross-Reference 7: Nachi 51114. Cross-Reference 8: Timken 51114. Cross-Reference 9: NTN-SNR 51114.
51214 is the heavier 512 series at the same 70 mm bore in a larger envelope, and 52214 is the double-direction version, so both are related sizes rather than interchanges.
Searchable designation forms: 51114, 51 114, 51-114, 51114 thrust bearing, 51114 grooved thrust ball bearing.
