SKF 1318 K, a double-row self-aligning ball bearing with a tapered bore. Bore: 90 mm. Outside Diameter: 190 mm. Overall Width: 43 mm. Bore Type: 1:12 tapered. Number Of Rows: 2. Rolling Elements: steel balls. Cage Material: pressed steel. Cage Type: pressed window cage. Closure Type: open. Internal Clearance: CN. Precision Class: P0 (ABEC 1). Dynamic Load Rating: 117 kN. Static Load Rating: 44 kN. Fatigue Load Limit: 1.93 kN. Reference Speed: 6,700 r/min. Limiting Speed: 4,500 r/min. Mass: 5.8 kg. Adapter sleeve: H318.
13 — SKF’s self-aligning ball bearing series 13, the wider of the two standard sections, with two ball rows running on a common sphered raceway in the outer ring.
18 — the bore code, 18 x 5 = 90 mm.
K — 1:12 tapered bore, mounts on an H318 adapter sleeve.
Dynamic Load Rating: 117 kN. Static Load Rating: 44 kN. Fatigue Load Limit: 1.93 kN. Reference Speed: 6,700 r/min is the thermally permitted figure and Limiting Speed: 4,500 r/min is the mechanical ceiling, so 4,500 r/min is the number to design to. The outer ring raceway is a single sphere with the inner ring, ball rows and cage free to swivel inside it, so the bearing tolerates several degrees of shaft-to-housing misalignment and shaft deflection with no rise in friction. That is why a self-aligning ball bearing is the standard choice for long line shafts, fans and conveyor drives where the two pedestals cannot be bored in one setting. Internal Clearance: CN. Cage Material: pressed steel. Mass: 5.8 kg.
Bore: 90 mm, 1:12 taper. Outside Diameter: 190 mm. Overall Width: 43 mm. The 90 mm tapered bore seats on an H318 adapter sleeve, whose tapered outside diameter is 90 mm over an 80 mm cylindrical shaft seat, secured with a KM 18 locknut and an MB 18 lockwasher. Driving the inner ring up the taper both grips the shaft and sets the running clearance by measured drive-up, so the shaft itself needs only a plain turned seat.
Unit Quantity: 1 Pc. Supplied as a single bearing.
Manufacturer part number variants: 1318 K, 1318K, 1318-K. The 1318 K envelope is an ISO-standard self-aligning ball size, so an FAG 1318-K-M-C3, NSK 1318 K and NTN 1318 K share the 90 x 190 x 43 mm boundary dimensions and the 1:12 taper. A straight-bore 1318 is the same bearing on a cylindrical seat and is a related size rather than an interchange; a 1318 KM carries a machined brass cage in place of the pressed steel one.
