How the SL024926 model number is decoded

envelope 130×180×50 mm with a 25.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 260 kN and C0 510 kN; with a C/C0 ratio of 0.51 the 50 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 64 kN, the limiting speed 2,090 r/min and the thermal reference speed 1,500 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 2.00 kN per millimetre of the 130 mm bore and 5.20 kN per millimetre of the 50 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 3.8 kg (3800 g) (0.42 g per mm² of the 180×50 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 130 mm bore, 180 mm outside diameter: at this size the 510 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs SL0249 is the double-row full-complement non-locating (floating) bearing: the flangeless outer ring moves freely over the rollers, taking only radial load while a separate bearing locates the shaft Two full roller rows give C 260 kN and C0 510 kN in a 180 mm outside diameter — the classic floating position opposite an SL0149 locating bearing Typical applications include vibrating and oscillating machinery, heavy industrial gearbox shafts and rope drums and winch drums, where the 180 mm outside diameter and 260 kN dynamic rating match the duty. In vibrating and oscillating machinery the unit fits a compact 130 mm seat, and in heavy industrial gearbox shafts the 3.8 kg mass is part of the rotor inertia calculation. Designers also specify it for rope drums and winch drums, relying on the 50 mm width and the published 510 kN static rating. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease. 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

  • rope drums and winch drums
  • compact slow-speed agitator drives
  • marine and offshore winch arrangements
  • hydraulic pumps and radial piston pumps

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

  • Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
  • 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.

Frequently asked questions

What are the dimensions of the SL024926?

The SL024926 is a SL0249 double-row full-complement non-locating cylindrical roller bearing with 180 mm outside diameter, 130 mm bore and 50 mm width, envelope 130×180×50 mm. Mass is 3.8 kg.

What does the SL024926 designation mean in the FAG/INA HR1 catalogue?

SL024926 identifies this SL0249 double-row full-complement non-locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 130×180×50 mm and the catalogue ratings are C 260 kN, C0 510 kN, Cur 64 kN.

What is the load capacity of the SL024926?

The basic dynamic load rating C is 260 kN and the basic static load rating C0 is 510 kN; the fatigue load limit Cur is 64 kN.

What is the maximum speed of the SL024926?

The limiting speed is 2,090 r/min and the thermal reference speed is 1,500 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 SL024926?

The SL0249 is non-locating: the flangeless outer ring floats freely and takes radial load only, making it the standard partner for a locating SL0149.
