How the SL183012-XL model number is decoded
envelope 60×95×26 mm with a 17.5 mm radial section; every available circumferential space carries a roller because there is no cage C is 123 kN and C0 143 kN; with a C/C0 ratio of 0.86 the 26 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 24.1 kN, the limiting speed 4,350 r/min and the thermal reference speed 3,000 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 2.05 kN per millimetre of the 60 mm bore and 4.73 kN per millimetre of the 26 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 690 g (0.28 g per mm² of the 95×26 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 60 mm bore this is a mainstream industrial size — conveyor drives, winches and medium gearboxes use the 26 mm width as a standard mounting space High radial rigidity at 123 kN C is the point of this design: rib-guided rollers in a cageless pack resist deflection in planetary gears, rope drums and vibrating machinery SL183012-XL is a single-row full-complement cylindrical roller bearing: no cage is fitted, so the maximum number of rollers runs between the rings, and the rollers guide themselves on the two inner-ring ribs X-life status (-XL) indicates the current Schaeffler premium execution at 60 mm bore; the 143 kN C0 rating reflects the improved rolling-contact geometry. Typical applications include compact slow-speed agitator drives, planetary gear bearing positions and crane travelling-wheel mechanisms, where the 95 mm outside diameter and 123 kN dynamic rating match the duty. In compact slow-speed agitator drives the unit fits a compact 60 mm seat, and in planetary gear bearing positions the 690 g mass suits the compact, space-optimised housing. Designers also specify it for crane travelling-wheel mechanisms, relying on the 26 mm width and the published 143 kN static rating. C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
Typical equipment & failure modes
Common applications
- hydraulic pumps and radial piston pumps
- heavy industrial gearbox shafts
- rolling-mill and steel-industry drives
- material handling conveyor pulleys
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
- C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
- Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
- 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.
Frequently asked questions
What are the dimensions of the SL183012-XL?
The SL183012-XL is a SL1830 single-row full-complement semi-locating cylindrical roller bearing with 95 mm outside diameter, 60 mm bore and 26 mm width, envelope 60×95×26 mm. Mass is 690 g.
What does the SL183012-XL designation mean in the FAG/INA HR1 catalogue?
SL183012-XL identifies this SL1830 single-row full-complement semi-locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue; the -XL suffix marks the X-life execution. The envelope is 60×95×26 mm and the catalogue ratings are C 123 kN, C0 143 kN, Cur 24.1 kN.
What is the load capacity of the SL183012-XL?
The basic dynamic load rating C is 123 kN and the basic static load rating C0 is 143 kN; the fatigue load limit Cur is 24.1 kN.
What is the maximum speed of the SL183012-XL?
The limiting speed is 4,350 r/min and the thermal reference speed is 3,000 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 SL183012-XL?
This is a semi-locating bearing: one rib on the outer ring and two on the inner ring guide the shaft axially in one direction, while the other direction is free for thermal expansion.
