How the SL014930 model number is decoded
envelope 150×210×60 mm with a 30.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 410 kN and C0 820 kN; with a C/C0 ratio of 0.50 the 60 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 106 kN, the limiting speed 1,790 r/min and the thermal reference speed 1,200 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 2.73 kN per millimetre of the 150 mm bore and 6.83 kN per millimetre of the 60 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 6.65 kg (6650 g) (0.53 g per mm² of the 210×60 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 150 mm bore puts this execution at the top of the HR1 range — the 210 mm outside diameter, 60 mm width and 6.65 kg mass are built for primary-industry load cases The outer ring carries an annular lubrication groove and holes, so the 410 kN dynamic rating can be maintained with relubrication without dismounting the 6.65 kg unit As the fixed (locating) bearing it takes the thermal-expansion thrust from the shaft while the paired floating bearing moves; the limiting speed here is 1,790 r/min Typical applications include heavy industrial gearbox shafts, crane travelling-wheel mechanisms and vibrating and oscillating machinery, where the 210 mm outside diameter and 410 kN dynamic rating match the duty. In heavy industrial gearbox shafts the unit fits a compact 150 mm seat, and in crane travelling-wheel mechanisms the 6.65 kg mass is part of the rotor inertia calculation. Designers also specify it for vibrating and oscillating machinery, relying on the 60 mm width and the published 820 kN static rating. 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. C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
Typical equipment & failure modes
Common applications
- marine and offshore winch arrangements
- crane travelling-wheel mechanisms
- hydraulic pumps and radial piston pumps
- rolling-mill and steel-industry drives
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
- 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.
- C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
- Press-fit the correct ring: the rotating ring needs interference while the floating ring must slide on its seat to perform the non-locating function.
Frequently asked questions
What are the dimensions of the SL014930?
The SL014930 is a SL0149 double-row full-complement locating cylindrical roller bearing with 210 mm outside diameter, 150 mm bore and 60 mm width, envelope 150×210×60 mm. Mass is 6.65 kg.
What does the SL014930 designation mean in the FAG/INA HR1 catalogue?
SL014930 identifies this SL0149 double-row full-complement locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 150×210×60 mm and the catalogue ratings are C 410 kN, C0 820 kN, Cur 106 kN.
What is the load capacity of the SL014930?
The basic dynamic load rating C is 410 kN and the basic static load rating C0 is 820 kN; the fatigue load limit Cur is 106 kN.
What is the maximum speed of the SL014930?
The limiting speed is 1,790 r/min and the thermal reference speed is 1,200 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 SL014930?
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.
