How the SL192352-TB-BR model number is decoded

envelope 260×540×165 mm with a 140.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 3550 kN and C0 4700 kN; with a C/C0 ratio of 0.76 the 165 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 465 kN, the limiting speed 760 r/min and the thermal reference speed 410 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 13.65 kN per millimetre of the 260 mm bore and 21.52 kN per millimetre of the 165 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 173.2 kg (173200 g) (1.94 g per mm² of the 540×165 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 260 mm bore, 540 mm outside diameter: at this size the 4700 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 760 r/min limiting speed the SL1923 is a slow-speed, high-load bearing — the cageless rollers trade kinematic speed for the 3550 kN dynamic rating -TB marks the TB execution with higher permissible axial load — the improved roller-end/rib lubrication film carries more thrust than the standard full-complement design. -BR marks the oxide-treated execution: the thin black conversion coating protects the 3550 kN-rated bearing before it enters lubricated service. Typical applications include rope drums and winch drums, vibrating and oscillating machinery and marine and offshore winch arrangements, where the 540 mm outside diameter and 3550 kN dynamic rating match the duty. In rope drums and winch drums the unit fits a compact 260 mm seat, and in vibrating and oscillating machinery the 173.2 kg mass is part of the rotor inertia calculation. Designers also specify it for marine and offshore winch arrangements, relying on the 165 mm width and the published 4700 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.
