How the SL192336-TB-BR model number is decoded

envelope 180×380×126 mm with a 100.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1940 kN and C0 2600 kN; with a C/C0 ratio of 0.75 the 126 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 285 kN, the limiting speed 1,120 r/min and the thermal reference speed 670 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 10.78 kN per millimetre of the 180 mm bore and 15.40 kN per millimetre of the 126 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 69.1 kg (69100 g) (1.44 g per mm² of the 380×126 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 180 mm bore, 380 mm outside diameter: at this size the 2600 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs Reading SL1923: full-complement roller set, no cage, self-guided rollers; the wide envelope is chosen where a narrow-section bearing would fit radially but lacks load capacity At 1,120 r/min limiting speed the SL1923 is a slow-speed, high-load bearing — the cageless rollers trade kinematic speed for the 1940 kN dynamic rating The -TB feature concerns the rib contact, not the envelope: the 180×380×126 mm dimensions and 69.1 kg mass follow the standard series plan. The -BR coating is a handling and storage protection; once mounted and greased, the 380 mm bearing operates to its normal 1,120 r/min limit. Typical applications include crane travelling-wheel mechanisms, compact slow-speed agitator drives and heavy industrial gearbox shafts, where the 380 mm outside diameter and 1940 kN dynamic rating match the duty. In crane travelling-wheel mechanisms the unit fits a compact 180 mm seat, and in compact slow-speed agitator drives the 69.1 kg mass is part of the rotor inertia calculation. Designers also specify it for heavy industrial gearbox shafts, relying on the 126 mm width and the published 2600 kN static rating. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease. 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.

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.
• 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.
• 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.
