How the SL183026 model number is decoded

envelope 130×200×52 mm with a 35.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 425 kN and C0 600 kN; with a C/C0 ratio of 0.71 the 52 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 84 kN, the limiting speed 1,990 r/min and the thermal reference speed 1,660 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.27 kN per millimetre of the 130 mm bore and 8.17 kN per millimetre of the 52 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 5.65 kg (5650 g) (0.54 g per mm² of the 200×52 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 130 mm bore this is among the largest catalogue sizes; the 1,990 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position Reading the designation: SL18 marks the Schaeffler full-complement semi-locating type with one rib on the outer ring and two ribs on the inner ring; the rollers are axially guided by the inner ring while the outer ring can displace by the catalogue s-value Typical applications include crane travelling-wheel mechanisms, compact slow-speed agitator drives and heavy industrial gearbox shafts, where the 200 mm outside diameter and 425 kN dynamic rating match the duty. In crane travelling-wheel mechanisms the unit fits a compact 130 mm seat, and in compact slow-speed agitator drives the 5.65 kg mass is part of the rotor inertia calculation. Designers also specify it for heavy industrial gearbox shafts, relying on the 52 mm width and the published 600 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. The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.

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.
• The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
• 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.
