How the SL185013-XL model number is decoded

envelope 65×100×46 mm with a 17.5 mm radial section; every available circumferential space carries a roller because there is no cage C is 223 kN and C0 315 kN; with a C/C0 ratio of 0.71 the 46 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 53 kN, the limiting speed 4,000 r/min and the thermal reference speed 2,500 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.43 kN per millimetre of the 65 mm bore and 4.85 kN per millimetre of the 46 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 1.32 kg (1320 g) (0.29 g per mm² of the 100×46 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 65 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 SL1850 denotes the double-row full-complement semi-locating bearing: two roller rows share the 65 mm bore, and the arrangement guides the shaft axially in one direction while allowing displacement s in the other Two cageless roller rows inside the 100×46 mm envelope give C 223 kN and C0 315 kN — among the highest radial capacities available at the 65 mm bore X-life status (-XL) indicates the current Schaeffler premium execution at 65 mm bore; the 315 kN C0 rating reflects the improved rolling-contact geometry. Typical applications include compact slow-speed agitator drives, planetary gear bearing positions and crane travelling-wheel mechanisms, where the 100 mm outside diameter and 223 kN dynamic rating match the duty. In compact slow-speed agitator drives the unit fits a compact 65 mm seat, and in planetary gear bearing positions the 1.32 kg mass is part of the rotor inertia calculation. Designers also specify it for crane travelling-wheel mechanisms, relying on the 46 mm width and the published 315 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

  • heavy industrial gearbox shafts
  • construction machinery slewing drives
  • vibrating and oscillating machinery
  • rope drums and winch drums

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 SL185013-XL?

The SL185013-XL is a SL1850 double-row full-complement semi-locating cylindrical roller bearing with 100 mm outside diameter, 65 mm bore and 46 mm width, envelope 65×100×46 mm. Mass is 1.32 kg.

What does the SL185013-XL designation mean in the FAG/INA HR1 catalogue?

SL185013-XL identifies this SL1850 double-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 65×100×46 mm and the catalogue ratings are C 223 kN, C0 315 kN, Cur 53 kN.

What is the load capacity of the SL185013-XL?

The basic dynamic load rating C is 223 kN and the basic static load rating C0 is 315 kN; the fatigue load limit Cur is 53 kN.

What is the maximum speed of the SL185013-XL?

The limiting speed is 4,000 r/min and the thermal reference speed is 2,500 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 SL185013-XL?

The SL1850 is semi-locating: it carries axial load in one direction and permits the catalogue s-displacement in the other.
