How the SL014914 model number is decoded
envelope 70×100×30 mm with a 15.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 106 kN and C0 185 kN; with a C/C0 ratio of 0.57 the 30 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 27.5 kN, the limiting speed 3,900 r/min and the thermal reference speed 2,330 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.51 kN per millimetre of the 70 mm bore and 3.53 kN per millimetre of the 30 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 780 g (0.26 g per mm² of the 100×30 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads with a 70 mm bore this is a heavy-industrial bearing: 780 g of stiff ring and roller set, specified where rigidity matters more than speed 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 3,900 r/min No angular compensation is built in: misalignment loads one roller row preferentially, so the housing and shaft seats for a 70 mm bore SL0149 must be machined parallel Typical applications include planetary gear bearing positions, construction machinery slewing drives and compact slow-speed agitator drives, where the 100 mm outside diameter and 106 kN dynamic rating match the duty. In planetary gear bearing positions the unit fits a compact 70 mm seat, and in construction machinery slewing drives the 780 g mass suits the compact, space-optimised housing. Designers also specify it for compact slow-speed agitator drives, relying on the 30 mm width and the published 185 kN static rating. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease. 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.
Typical equipment & failure modes
Common applications
- rolling-mill and steel-industry drives
- vibrating and oscillating machinery
- material handling conveyor pulleys
- construction machinery slewing 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
- Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
- 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.
- Use the rib structure correctly: SL18/SL1850 give one-direction axial guidance, SL0149 locates both ways and SL0249 floats — pairing two locating bearings on one shaft binds thermal growth.
Frequently asked questions
What are the dimensions of the SL014914?
The SL014914 is a SL0149 double-row full-complement locating cylindrical roller bearing with 100 mm outside diameter, 70 mm bore and 30 mm width, envelope 70×100×30 mm. Mass is 780 g.
What does the SL014914 designation mean in the FAG/INA HR1 catalogue?
SL014914 identifies this SL0149 double-row full-complement locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 70×100×30 mm and the catalogue ratings are C 106 kN, C0 185 kN, Cur 27.5 kN.
What is the load capacity of the SL014914?
The basic dynamic load rating C is 106 kN and the basic static load rating C0 is 185 kN; the fatigue load limit Cur is 27.5 kN.
What is the maximum speed of the SL014914?
The limiting speed is 3,900 r/min and the thermal reference speed is 2,330 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 SL014914?
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.
