How the SL014924 model number is decoded
envelope 120×165×45 mm with a 22.5 mm radial section; every available circumferential space carries a roller because there is no cage C is 222 kN and C0 440 kN; with a C/C0 ratio of 0.50 the 45 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 56 kN, the limiting speed 2,260 r/min and the thermal reference speed 1,540 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.85 kN per millimetre of the 120 mm bore and 4.93 kN per millimetre of the 45 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 2.95 kg (2950 g) (0.40 g per mm² of the 165×45 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 120 mm bore belongs to the large band, where HR1 full-complement and track-roller designs deliver their highest kilonewton ratings in slow, heavily loaded machinery Reading SL0149: the DIN 5412-9 type code family NNC49, double-row full complement with split outer ring; the joining retaining rings must not be used to transmit axial force No angular compensation is built in: misalignment loads one roller row preferentially, so the housing and shaft seats for a 120 mm bore SL0149 must be machined parallel Typical applications include rope drums and winch drums, vibrating and oscillating machinery and marine and offshore winch arrangements, where the 165 mm outside diameter and 222 kN dynamic rating match the duty. In rope drums and winch drums the unit fits a compact 120 mm seat, and in vibrating and oscillating machinery the 2.95 kg mass is part of the rotor inertia calculation. Designers also specify it for marine and offshore winch arrangements, relying on the 45 mm width and the published 440 kN static rating. There is no cage: do not apply caged-bearing speed rules — the printed limiting speed is a hard kinematic ceiling set by roller-to-roller contact. The split outer ring of SL0149 is joined by retaining rings for handling only; never use those rings as a thrust face in the design.
Typical equipment & failure modes
Common applications
- planetary gear bearing positions
- hydraulic pumps and radial piston pumps
- compact slow-speed agitator drives
- crane travelling-wheel mechanisms
Known failure patterns
- raceway pitting from overloaded slow-speed positions where the cageless rollers repeatedly stress one contact band
- rib and roller-end scoring when applied axial thrust exceeds the semi-locating capacity
- roller smearing from roller-to-roller sliding at speeds above the limiting value
- edge loading and premature spalling caused by undetected shaft/housing misalignment (full-complement rows cannot self-align)
- brinelling of the raceways from static shock during mounting or transport of the heavy rotor
- lubricant starvation in the tightly packed roller set, especially in the double-row executions
- freting and creep on a loose ring seat under a rotating load
- contamination wear in open gearbox positions with damaged seals or breathers
- false brinelling from micro-movement while the shaft is stationary under vibration
Selection pitfalls — read before you substitute
- There is no cage: do not apply caged-bearing speed rules — the printed limiting speed is a hard kinematic ceiling set by roller-to-roller contact.
- The split outer ring of SL0149 is joined by retaining rings for handling only; never use those rings as a thrust face in the design.
- Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
Frequently asked questions
What are the dimensions of the SL014924?
The SL014924 is a SL0149 double-row full-complement locating cylindrical roller bearing with 165 mm outside diameter, 120 mm bore and 45 mm width, envelope 120×165×45 mm. Mass is 2.95 kg.
What does the SL014924 designation mean in the FAG/INA HR1 catalogue?
SL014924 identifies this SL0149 double-row full-complement locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 120×165×45 mm and the catalogue ratings are C 222 kN, C0 440 kN, Cur 56 kN.
What is the load capacity of the SL014924?
The basic dynamic load rating C is 222 kN and the basic static load rating C0 is 440 kN; the fatigue load limit Cur is 56 kN.
What is the maximum speed of the SL014924?
The limiting speed is 2,260 r/min and the thermal reference speed is 1,540 r/min. In the Schaeffler catalogue the reference speed is the thermally permissible running speed under defined load; the lower of the two values governs each application.
What is the locating function of the SL014924?
The SL0149 is a locating bearing: it fixes the shaft axially in both directions; pair it with a non-locating SL0249 at the other end to avoid binding.
