How the SL183076-TB model number is decoded

envelope 380×560×135 mm with a 90.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 2600 kN and C0 4450 kN; with a C/C0 ratio of 0.58 the 135 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 430 kN, the limiting speed 660 r/min and the thermal reference speed 390 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 6.84 kN per millimetre of the 380 mm bore and 19.26 kN per millimetre of the 135 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 106 kg (106000 g) (1.40 g per mm² of the 560×135 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 380 mm bore puts this execution at the top of the HR1 range — the 560 mm outside diameter, 135 mm width and 106 kg mass are built for primary-industry load cases 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 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 The -TB feature concerns the rib contact, not the envelope: the 380×560×135 mm dimensions and 106 kg mass follow the standard series plan. Typical applications include compact slow-speed agitator drives, planetary gear bearing positions and crane travelling-wheel mechanisms, where the 560 mm outside diameter and 2600 kN dynamic rating match the duty. In compact slow-speed agitator drives the unit fits a compact 380 mm seat, and in planetary gear bearing positions the 106 kg mass is part of the rotor inertia calculation. Designers also specify it for crane travelling-wheel mechanisms, relying on the 135 mm width and the published 4450 kN static rating. The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling. 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.

Selection pitfalls — read before you substitute

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