How the SL182222 model number is decoded
envelope 110×200×53 mm with a 45.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 450 kN and C0 580 kN; with a C/C0 ratio of 0.78 the 53 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 83 kN, the limiting speed 2,130 r/min and the thermal reference speed 1,720 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 4.09 kN per millimetre of the 110 mm bore and 8.49 kN per millimetre of the 53 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 7.24 kg (7240 g) (0.68 g per mm² of the 200×53 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 110 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 The semi-locating function means this bearing locates the shaft in one axial direction and floats in the other — useful in two-bearing shafts where one position is fixed and the other absorbs expansion The dimension-series digits place this bearing in the SL18 section of the HR1 plan, giving the 45.0 mm section height between the 110 mm bore and the 200 mm outside diameter Typical applications include vibrating and oscillating machinery, heavy industrial gearbox shafts and rope drums and winch drums, where the 200 mm outside diameter and 450 kN dynamic rating match the duty. In vibrating and oscillating machinery the unit fits a compact 110 mm seat, and in heavy industrial gearbox shafts the 7.24 kg mass is part of the rotor inertia calculation. Designers also specify it for rope drums and winch drums, relying on the 53 mm width and the published 580 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. 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.
Typical equipment & failure modes
Common applications
- compact slow-speed agitator drives
- rolling-mill and steel-industry drives
- crane travelling-wheel mechanisms
- heavy industrial gearbox shafts
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.
- 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.
- C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
Frequently asked questions
What are the dimensions of the SL182222?
The SL182222 is a SL1822 single-row full-complement semi-locating cylindrical roller bearing with 200 mm outside diameter, 110 mm bore and 53 mm width, envelope 110×200×53 mm. Mass is 7.24 kg.
What does the SL182222 designation mean in the FAG/INA HR1 catalogue?
SL182222 identifies this SL1822 single-row full-complement semi-locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 110×200×53 mm and the catalogue ratings are C 450 kN, C0 580 kN, Cur 83 kN.
What is the load capacity of the SL182222?
The basic dynamic load rating C is 450 kN and the basic static load rating C0 is 580 kN; the fatigue load limit Cur is 83 kN.
What is the maximum speed of the SL182222?
The limiting speed is 2,130 r/min and the thermal reference speed is 1,720 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 SL182222?
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.
