How the SL182922-XL model number is decoded
envelope 110×150×24 mm with a 20.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 155 kN and C0 213 kN; with a C/C0 ratio of 0.73 the 24 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 34.5 kN, the limiting speed 2,500 r/min and the thermal reference speed 1,710 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.41 kN per millimetre of the 110 mm bore and 6.46 kN per millimetre of the 24 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 1.23 kg (1230 g) (0.34 g per mm² of the 150×24 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads with a 110 mm bore this is a heavy-industrial bearing: 1.23 kg of stiff ring and roller set, specified where rigidity matters more than speed SL182922-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 The -XL suffix marks the X-life execution: refined raceway topography and upgraded materials lift the basic ratings versus the non-X-life bearing at the same 110×150×24 mm envelope. Typical applications include rolling-mill and steel-industry drives, hydraulic pumps and radial piston pumps and material handling conveyor pulleys, where the 150 mm outside diameter and 155 kN dynamic rating match the duty. In rolling-mill and steel-industry drives the unit fits a compact 110 mm seat, and in hydraulic pumps and radial piston pumps the 1.23 kg mass is part of the rotor inertia calculation. Designers also specify it for material handling conveyor pulleys, relying on the 24 mm width and the published 213 kN static rating. 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. 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.
Typical equipment & failure modes
Common applications
- vibrating and oscillating machinery
- planetary gear bearing positions
- rope drums and winch drums
- marine and offshore winch arrangements
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
- 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.
- 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.
Frequently asked questions
What are the dimensions of the SL182922-XL?
The SL182922-XL is a SL1829 single-row full-complement semi-locating cylindrical roller bearing with 150 mm outside diameter, 110 mm bore and 24 mm width, envelope 110×150×24 mm. Mass is 1.23 kg.
What does the SL182922-XL designation mean in the FAG/INA HR1 catalogue?
SL182922-XL identifies this SL1829 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 110×150×24 mm and the catalogue ratings are C 155 kN, C0 213 kN, Cur 34.5 kN.
What is the load capacity of the SL182922-XL?
The basic dynamic load rating C is 155 kN and the basic static load rating C0 is 213 kN; the fatigue load limit Cur is 34.5 kN.
What is the maximum speed of the SL182922-XL?
The limiting speed is 2,500 r/min and the thermal reference speed is 1,710 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 SL182922-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.
