INASL014916-ADouble Row Full Complement Cylindrical Roller Bearing — 80 mm ID, 110 mm OD, 30 mm Width, Locating Design, CN Clearance

Product Description

What this part is:

INA SL01 4916 A, a double-row full-complement cylindrical roller bearing. Bore: 80 mm. Outside Diameter: 110 mm. Overall Width: 30 mm. Number Of Rows: 2. Rolling Elements: cylindrical rollers, full complement. Bore Type: cylindrical. Closure Type: open. Internal Clearance: CN. Precision Class: PN (normal). Dynamic Load Rating: 112 kN. Static Load Rating: 206 kN. Fatigue Limit Load: 30.5 kN. Limiting Speed: 3,550 rpm. Reference Speed: 2,090 rpm. Mass: 0.88 kg. Country of origin as marked: Germany.

Decoding the designation:

SL01 — INA’s double-row full-complement cylindrical roller series, ribbed on both rings so the bearing locates the shaft axially in both directions.

49 — dimension series 49, the narrow-section series that puts the whole capacity into a 15 mm radial wall.

16 — the bore code, 16 x 5 = 80 mm.

A — the current INA design execution of this reference.

What these specs mean in practice:

Dynamic Load Rating: 112 kN. Static Load Rating: 206 kN. Full complement means the space that would hold a cage holds rollers instead, so both figures come out far above a caged bearing of the same envelope, and the static figure standing well above the dynamic one is the published relationship for this construction. Fatigue Limit Load: 30.5 kN. Limiting Speed: 3,550 rpm is the mechanical ceiling; Reference Speed: 2,090 rpm is the thermally permitted figure, and on a full-complement bearing the thermal figure is the binding one because roller-to-roller sliding generates the heat. Internal Clearance: CN. Precision Class: PN, normal tolerance. Ribs on both rings make this a locating bearing: it takes the radial load and fixes the shaft axially in the same position. Mass: 0.88 kg.

Mounting data:

Bore: 80 mm, cylindrical. Outside Diameter: 110 mm. Overall Width: 30 mm. Radial section: 15 mm. Both rings are ribbed and the bearing is non-separable, so it presses on and out as one unit and locates the shaft in both axial directions from a single seat.

Quantity and configuration:

Unit Quantity: 1 Pc. Supplied as a single bearing.

Interchange guidance:

Manufacturer part number variants: SL014916, SL01 4916 A, SL014916-A, SL01-4916-A. Cross-Reference: NNC4916V, the ISO designation for the same double-row full-complement construction on the 80 x 110 x 30 mm envelope. An SL184916 is the caged execution on the same envelope and carries different load and speed figures, so it is a related size rather than an interchange.
