How the SL182232 model number is decoded
envelope 160×290×80 mm with a 65.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1020 kN and C0 1470 kN; with a C/C0 ratio of 0.69 the 80 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 187 kN, the limiting speed 1,370 r/min and the thermal reference speed 920 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 6.38 kN per millimetre of the 160 mm bore and 12.75 kN per millimetre of the 80 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 23 kg (23000 g) (0.99 g per mm² of the 290×80 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 160 mm bore this is among the largest catalogue sizes; the 1,370 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position 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 High radial rigidity at 1020 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 Typical applications include material handling conveyor pulleys, rolling-mill and steel-industry drives and construction machinery slewing drives, where the 290 mm outside diameter and 1020 kN dynamic rating match the duty. In material handling conveyor pulleys the unit fits a compact 160 mm seat, and in rolling-mill and steel-industry drives the 23 kg mass is part of the rotor inertia calculation. Designers also specify it for construction machinery slewing drives, relying on the 80 mm width and the published 1470 kN static rating. The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling. 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
- 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
- The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
- 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.
- Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
Frequently asked questions
What are the dimensions of the SL182232?
The SL182232 is a SL1822 single-row full-complement semi-locating cylindrical roller bearing with 290 mm outside diameter, 160 mm bore and 80 mm width, envelope 160×290×80 mm. Mass is 23 kg.
What does the SL182232 designation mean in the FAG/INA HR1 catalogue?
SL182232 identifies this SL1822 single-row full-complement semi-locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 160×290×80 mm and the catalogue ratings are C 1020 kN, C0 1470 kN, Cur 187 kN.
What is the load capacity of the SL182232?
The basic dynamic load rating C is 1020 kN and the basic static load rating C0 is 1470 kN; the fatigue load limit Cur is 187 kN.
What is the maximum speed of the SL182232?
The limiting speed is 1,370 r/min and the thermal reference speed is 920 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 SL182232?
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.
