SKF 6312-Z single-row deep groove ball bearing with one pressed steel shield. Bore Diameter: 60 mm. Outside Diameter: 130 mm. Overall Width: 31 mm. Number Of Rows: 1. Rolling Elements: Ball. Bore Type: Cylindrical. Closure Type: Shielded one side. Internal Clearance: CN. Bearing Material: Bearing steel. Series: 63. Base Number: 6312.
6312 is the ISO 63 heavy series at a 60 mm bore — a thicker cross-section and a bigger ball set than the 62-series bearing of the same bore, which is where the load rating comes from. A single Z is one shield, with the opposite face open. No clearance suffix appears, so the bearing is supplied to normal radial internal clearance. Written as 6312Z, 6312-Z and 6312 Z.
Dynamic Load Rating: 85,200 N. Static Load Rating: 52,000 N. Reference Speed: 11,000 rpm. Limiting Speed: 7,000 rpm. SKF Explorer is SKF’s upgraded steel and surface specification and is what puts the dynamic rating at this level on a 60 mm bore. One shield suits a position where grease is retained on the exposed side and the other face sits against a housing cover or a lubrication feed.
Unit Quantity: 1 Pc. One bearing per sale unit, one face shielded and one face open.
Shaft abutment diameter: 72 mm minimum to 81.8 mm maximum. Housing abutment diameter: 118 mm maximum. Bearing chamfer r1,2: 2.1 mm minimum. Inner ring shoulder diameter: approximately 81.86 mm. Outer ring recess diameter: approximately 112.2 mm. ISO tolerance class for dimensions: Normal.
6312 is an ISO-pattern designation and the single-shield suffix translates directly. Cross-Reference 1: FAG 6312-Z. Cross-Reference 2: NSK 6312Z. Cross-Reference 3: NTN 6312Z. Cross-Reference 4: Koyo 6312Z. Cross-Reference 5: NACHI 6312Z. Searchable forms: 6312Z, 6312-Z, 6312 Z, 6312.
