How the SL192324-TB-XL-BR model number is decoded

envelope 120×260×86 mm with a 70.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1130 kN and C0 1230 kN; with a C/C0 ratio of 0.92 the 86 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 204 kN, the limiting speed 1,690 r/min and the thermal reference speed 1,120 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 9.42 kN per millimetre of the 120 mm bore and 13.14 kN per millimetre of the 86 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 22.3 kg (22300 g) (1.00 g per mm² of the 260×86 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 120 mm bore the 260 mm outside diameter and 86 mm width target rolling stands, construction machinery and heavy gearboxes; the limiting speed drops to 1,690 r/min Reading SL1923: full-complement roller set, no cage, self-guided rollers; the wide envelope is chosen where a narrow-section bearing would fit radially but lacks load capacity X-life status (-XL) indicates the current Schaeffler premium execution at 120 mm bore; the 1230 kN C0 rating reflects the improved rolling-contact geometry. Reading -TB: Schaeffler's enhanced-rib design for full-complement bearings; axial friction torque is reduced while radial ratings stay at 1130 kN C. The -BR coating is a handling and storage protection; once mounted and greased, the 260 mm bearing operates to its normal 1,690 r/min limit. Typical applications include planetary gear bearing positions, construction machinery slewing drives and compact slow-speed agitator drives, where the 260 mm outside diameter and 1130 kN dynamic rating match the duty. In planetary gear bearing positions the unit fits a compact 120 mm seat, and in construction machinery slewing drives the 22.3 kg mass is part of the rotor inertia calculation. Designers also specify it for compact slow-speed agitator drives, relying on the 86 mm width and the published 1230 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. 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

  • planetary gear bearing positions
  • hydraulic pumps and radial piston pumps
  • compact slow-speed agitator drives
  • crane travelling-wheel mechanisms

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.
  • 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 SL192324-TB-XL-BR?

The SL192324-TB-XL-BR is a SL1923 single-row full-complement semi-locating cylindrical roller bearing with 260 mm outside diameter, 120 mm bore and 86 mm width, envelope 120×260×86 mm. Mass is 22.3 kg.

What does the SL192324-TB-XL-BR designation mean in the FAG/INA HR1 catalogue?

SL192324-TB-XL-BR identifies this SL1923 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 120×260×86 mm and the catalogue ratings are C 1130 kN, C0 1230 kN, Cur 204 kN.

What is the load capacity of the SL192324-TB-XL-BR?

The basic dynamic load rating C is 1130 kN and the basic static load rating C0 is 1230 kN; the fatigue load limit Cur is 204 kN.

What is the maximum speed of the SL192324-TB-XL-BR?

The limiting speed is 1,690 r/min and the thermal reference speed is 1,120 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 SL192324-TB-XL-BR?

This is a semi-locating bearing: it locates the shaft in one axial direction and floats in the other, and should be paired with a non-locating or locating bearing accordingly.
