How the SL192332-TB-BR model number is decoded

envelope 160×340×114 mm with a 90.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1690 kN and C0 2170 kN; with a C/C0 ratio of 0.78 the 114 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 244 kN, the limiting speed 1,250 r/min and the thermal reference speed 760 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 10.56 kN per millimetre of the 160 mm bore and 14.82 kN per millimetre of the 114 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 49.7 kg (49700 g) (1.28 g per mm² of the 340×114 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 160 mm bore this is among the largest catalogue sizes; the 1,250 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position SL192332-TB-BR is the wide dimension-series 23 execution of the single-row full-complement principle: a markedly wider 114 mm ring carries more and longer rollers than the 29/30-series sizes The 114 mm width versus 340 mm outside diameter gives this series its characteristic squat proportions and high tipping rigidity under eccentric loads -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-finished surfaces tolerate damp assembly environments better than bare steel, which matters for the large 49.7 kg industrial executions. Typical applications include compact slow-speed agitator drives, planetary gear bearing positions and crane travelling-wheel mechanisms, where the 340 mm outside diameter and 1690 kN dynamic rating match the duty. In compact slow-speed agitator drives the unit fits a compact 160 mm seat, and in planetary gear bearing positions the 49.7 kg mass is part of the rotor inertia calculation. Designers also specify it for crane travelling-wheel mechanisms, relying on the 114 mm width and the published 2170 kN static rating. 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. The split outer ring of SL0149 is joined by retaining rings for handling only; never use those rings as a thrust face in the design.

Selection pitfalls — read before you substitute

• 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.
• The split outer ring of SL0149 is joined by retaining rings for handling only; never use those rings as a thrust face in the design.
• Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
