How the NCF2892-V-HB1 model number is decoded
For a 460 mm shaft, SKF lists NCF2892-V-HB1 as single-row full-complement cylindrical roller: 580 mm OD, 72 mm wide, Pu 260 kN, the catalogue lists 430 r/min thermal reference speed and 530 r/min mechanical limiting speed. Reading the NCF prefix: a non-separable single-row full complement bearing with two integral flanges on the inner ring, one integral flange on the outer ring and a retaining ring opposite that flange holding the assembly together. This makes the execution one-direction locating: the integral outer-ring flange locates the shaft in one direction; the retaining ring side must not be used to guide axial displacement. Suffix V/HB1 identifies the full-complement execution: the space a cage would occupy is filled with extra rollers, trading speed for maximum radial capacity and stiffness. Load-per-bore for the 460 mm seat is about 2.83 kN/mm, typical of dimension series 28 (slim section, wide); use C0 3050 kN for static checks such as crane hook blocks standing under load. Assembly note: uncaged rollers demand adequate minimum load and gentle acceleration; do not load the retaining ring axially and relubricate generously to prevent roller smearing. Heat steel rings inductively to max 120 °C, and never wash a full-complement unit in a way that displaces rollers.
Typical equipment & failure modes
Common applications
- large rolling-mill and continuous-caster drives
- mining crusher eccentric shafts
- heavy offshore winch drums
Known failure patterns
- inner-ring raceway spalling from overload or contamination in the line-contact hertz zone
- outer-ring raceway fatigue after extended service at loads above the catalogue L10 rating
- roller smearing (microwelding) in the full complement during skidding at light load or rapid acceleration
- cage pocket wear from roller skidding at insufficient radial load or during start-up before oil film build-up
- roller-end scoring from inadequate oil flow in the roller-raceway contact
- edge loading and roller-end scoring when the minimum radial load is not maintained at standstill
- fretting corrosion on a loose rotating shaft seat or in a vibratory stand-still
Selection pitfalls — read before you substitute
- Full-complement bearings trade speed for capacity: the 530 r/min ceiling is far below a caged bearing of the same envelope, and running faster smears the uncaged rollers.
- Keep minimum radial load high (typically ≥0,02 C) for a full-complement unit; at light load the rollers skid and microweld within the first service interval.
- Shaft and housing fillets must clear the bearing chamfers; an oversized radius tilts the 72 mm-wide ring and concentrates load.
- Catalogue reference and limiting speeds are different criteria: observe the mechanical ceiling even when thermal calculations allow more.
- The 1300/3050 kN ratings are SKF catalogue 17000 (2018) values for the V/HB1 execution; re-verify against the current catalogue for critical drives and keep the catalogue version with the specification.
Frequently asked questions
What are the dimensions and catalogue data of NCF2892-V-HB1?
SKF NCF 2892 V/HB1 is a single-row full-complement cylindrical roller bearing with 460 mm bore, 580 mm OD and 72 mm width per ISO 15. SKF lists C 1300 kN, C0 3050 kN, Pu 260 kN, reference speed 430 r/min and limiting speed 530 r/min, mass about 44000 g.
What does the NCF designation and V/HB1 suffix mean?
Suffix V/HB1 identifies the full-complement execution: the space a cage would occupy is filled with extra rollers, trading speed for maximum radial capacity and stiffness. Structurally this execution has a non-separable single-row full complement bearing with two integral flanges on the inner ring, one integral flange on the outer ring and a retaining ring opposite that flange holding the assembly together.
Can NCF2892-V-HB1 take axial load and locate the shaft?
In one direction, against the integral outer-ring flange side. The retaining ring holds the bearing together and must not be axially loaded.
How does NCF2892-V-HB1 compare with the other executions in the same envelope?
The full-complement NCF/NJG bearings replace the cage with extra rollers for higher radial capacity and stiffness at a substantially lower speed than caged bearings.
What limits the service life of this bearing most often?
On full-complement bearings the dominant risks are roller smearing from skidding below minimum load and contamination; maintain minimum radial load, keep lubricant film thick and accelerate gently.
