How the SL182206-XL model number is decoded

envelope 30×62×20 mm with a 16.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 70 kN and C0 64 kN; with a C/C0 ratio of 1.09 the 20 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 10.4 kN, the limiting speed 7,400 r/min and the thermal reference speed 4,550 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 2.33 kN per millimetre of the 30 mm bore and 3.50 kN per millimetre of the 20 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 300 g (0.24 g per mm² of the 62×20 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 30 mm bore falls in the small band, the workhorse size for gearbox planetary positions, hydraulic pumps and general cam and linkage duty SL18 bearings are separable for mounting: the inner ring with the self-retained roller set can be fitted separately from the plain-bored outer ring, which simplifies interference-fit assembly The dimension-series digits place this bearing in the SL18 section of the HR1 plan, giving the 16.0 mm section height between the 30 mm bore and the 62 mm outside diameter -XL means this is an X-life bearing — Schaeffler's upgraded performance level with smoother raceways, so the 70 kN C rating and longer nominal life come without an envelope change. Typical applications include marine and offshore winch arrangements, rope drums and winch drums and hydraulic pumps and radial piston pumps, where the 62 mm outside diameter and 70 kN dynamic rating match the duty. In marine and offshore winch arrangements the unit fits a compact 30 mm seat, and in rope drums and winch drums the 300 g mass suits the compact, space-optimised housing. Designers also specify it for hydraulic pumps and radial piston pumps, relying on the 20 mm width and the published 64 kN static rating. C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film. 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.

Typical equipment & failure modes

Common applications

  • material handling conveyor pulleys
  • rope drums and winch drums
  • construction machinery slewing drives
  • planetary gear bearing positions

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

  • C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
  • 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.
  • The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.

Frequently asked questions

What are the dimensions of the SL182206-XL?

The SL182206-XL is a SL1822 single-row full-complement semi-locating cylindrical roller bearing with 62 mm outside diameter, 30 mm bore and 20 mm width, envelope 30×62×20 mm. Mass is 300 g.

What does the SL182206-XL designation mean in the FAG/INA HR1 catalogue?

SL182206-XL identifies this SL1822 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 30×62×20 mm and the catalogue ratings are C 70 kN, C0 64 kN, Cur 10.4 kN.

What is the load capacity of the SL182206-XL?

The basic dynamic load rating C is 70 kN and the basic static load rating C0 is 64 kN; the fatigue load limit Cur is 10.4 kN.

What is the maximum speed of the SL182206-XL?

The limiting speed is 7,400 r/min and the thermal reference speed is 4,550 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 SL182206-XL?

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.
