SKF 234416-BM1/SP is a double-direction axial angular contact thrust ball bearing from the SKF ball-screw-support family, series 2344. One complete bearing, new. The design is separable and is supplied as a matched component set: two shaft washers, one spacer, one housing washer and two ball-and-cage assemblies, matched at the factory.
234416 — base number: series 2344, 80 mm bore, 125 mm outside diameter, 54 mm width.
BM1 — machined brass cage, retained on the shaft washer.
SP — special precision, a restricted-tolerance class with tightened running accuracy and closer axial location.
Bore Diameter: 80 mm. Outside Diameter: 125 mm. Total Width: 54 mm. Outer Ring Width: 27 mm. Contact Angle: 60°. Number Of Rows: 2. Rolling Elements: Ball. Cage: Machined brass. Dynamic Axial Load Rating: 57 kN. Static Axial Load Rating: 173 kN. Fatigue Load Limit, Axial: 15.7 kN. Axial Rigidity: 640 N/µm. Preload Force: 400 N. Limiting Speed: 4,500 rpm grease; 6,000 rpm oil. Item Weight: 2.155 kg (4.75 lb). Bore Type: Straight.
Shaft shoulder diameter: 98.5 mm to h12. Outer ring shoulder diameter: 117 mm to H12. Maximum shaft recess radius: 1.1 mm. Distance between pressure-cone apexes: 207 mm. Lubrication hole diameter: 3.2 mm. Lubricating groove in the outer ring: 6.5 mm.
Cross-references: FAG 234416-M-SP, NSK 80TAC20D. Punctuation variants of the designation: 234416 BM1/SP, 234416BM1SP, 234416-BM1-SP. Application types: ball screw support on machining centres, lathes, grinding and milling machines.
Bore 80 mm, outside diameter 125 mm, total width 54 mm, outer ring width 27 mm.
Contact angle 60°. Dynamic axial load rating 57 kN and static axial load rating 173 kN.
BM1 is a machined brass cage. SP is the special precision tolerance class.
