How the NJG2313-VH model number is decoded
SKF NJG 2313 VH is a single-row full-complement cylindrical roller bearing sized 65×140×48 mm — a dimension series 23 (medium-section, wide), listed in SKF catalogue PUB BU/P1 17000 ch. 6.3. Reading the NJG prefix: a single-row full complement bearing with two integral flanges on the outer ring and one on the inner ring; the roller set is self-retaining and the outer ring can be lifted off without rollers spilling. This makes the execution one-direction locating: it positions the shaft axially in one direction and accommodates axial displacement in the opposite direction. Reading the order-string suffix VH: the full-complement execution — extra rollers replace the cage, trading speed for maximum radial capacity and stiffness. With C 303 kN and C0 360 kN, size the bearing on the 65×140 mm ISO 15 envelope and check the 46.5 kN Pu against the equivalent-load floor; the catalogue lists 1,900 r/min thermal reference speed and 2,400 r/min mechanical limiting speed. Mounting: low-speed duty only: the uncaged rollers smear when skidding, so keep minimum radial load high, accelerate gently and favour oil bath or grease with high base-oil viscosity. A 65 mm seat normally takes a k5 interference with an H6 housing bore when the inner ring rotates.
Typical equipment & failure modes
Common applications
- wind turbine rotor-lock and yaw drives
- large gearbox slow-speed stages
- rolling-mill auxiliary shafts
- heavy conveyor pulley bearings
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
- rolling-contact fatigue spalling after the rated L10 life is exceeded
Selection pitfalls — read before you substitute
- Full-complement bearings trade speed for capacity: the 2,400 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 48 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 303/360 kN ratings are SKF catalogue 17000 (2018) values for the VH 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 NJG2313-VH?
SKF NJG 2313 VH is a single-row full-complement cylindrical roller bearing with 65 mm bore, 140 mm OD and 48 mm width per ISO 15. SKF lists C 303 kN, C0 360 kN, Pu 46.5 kN, reference speed 1,900 r/min and limiting speed 2,400 r/min, mass about 3550 g.
What does the NJG designation and VH suffix mean?
Suffix VH 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 single-row full complement bearing with two integral flanges on the outer ring and one on the inner ring; the roller set is self-retaining and the outer ring can be lifted off without rollers spilling.
Can NJG2313-VH take axial load and locate the shaft?
In one direction; the opposite direction accommodates displacement. It is a low-speed full-complement bearing, not a high-speed thrust solution.
How does NJG2313-VH 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.
