How the SL183032 model number is decoded
envelope 160×240×60 mm with a 40.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 540 kN and C0 800 kN; with a C/C0 ratio of 0.68 the 60 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 105 kN, the limiting speed 1,600 r/min and the thermal reference speed 1,280 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.38 kN per millimetre of the 160 mm bore and 9.00 kN per millimetre of the 60 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 8.8 kg (8800 g) (0.61 g per mm² of the 240×60 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 1,600 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 The dimension-series digits place this bearing in the SL18 section of the HR1 plan, giving the 40.0 mm section height between the 160 mm bore and the 240 mm outside diameter Typical applications include planetary gear bearing positions, construction machinery slewing drives and compact slow-speed agitator drives, where the 240 mm outside diameter and 540 kN dynamic rating match the duty. In planetary gear bearing positions the unit fits a compact 160 mm seat, and in construction machinery slewing drives the 8.8 kg mass is part of the rotor inertia calculation. Designers also specify it for compact slow-speed agitator drives, relying on the 60 mm width and the published 800 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
- 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
- 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 SL183032?
The SL183032 is a SL1830 single-row full-complement semi-locating cylindrical roller bearing with 240 mm outside diameter, 160 mm bore and 60 mm width, envelope 160×240×60 mm. Mass is 8.8 kg.
What does the SL183032 designation mean in the FAG/INA HR1 catalogue?
SL183032 identifies this SL1830 single-row full-complement semi-locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 160×240×60 mm and the catalogue ratings are C 540 kN, C0 800 kN, Cur 105 kN.
What is the load capacity of the SL183032?
The basic dynamic load rating C is 540 kN and the basic static load rating C0 is 800 kN; the fatigue load limit Cur is 105 kN.
What is the maximum speed of the SL183032?
The limiting speed is 1,600 r/min and the thermal reference speed is 1,280 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 SL183032?
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.
