How the SL192330-TB-BR model number is decoded

envelope 150×320×108 mm with a 85.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1490 kN and C0 1900 kN; with a C/C0 ratio of 0.78 the 108 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 235 kN, the limiting speed 1,350 r/min and the thermal reference speed 840 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 9.93 kN per millimetre of the 150 mm bore and 13.80 kN per millimetre of the 108 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 42.1 kg (42100 g) (1.22 g per mm² of the 320×108 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 150 mm bore, 320 mm outside diameter: at this size the 1900 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs At 1,350 r/min limiting speed the SL1923 is a slow-speed, high-load bearing — the cageless rollers trade kinematic speed for the 1490 kN dynamic rating SL1923 bearings are semi-locating, with one outer-ring rib and two inner-ring ribs; the wide section delivers extreme C0 — 1900 kN at 150 mm bore — for slow heavy positions The -TB feature concerns the rib contact, not the envelope: the 150×320×108 mm dimensions and 42.1 kg mass follow the standard series plan. BR-finished surfaces tolerate damp assembly environments better than bare steel, which matters for the large 42.1 kg industrial executions. Typical applications include vibrating and oscillating machinery, heavy industrial gearbox shafts and rope drums and winch drums, where the 320 mm outside diameter and 1490 kN dynamic rating match the duty. In vibrating and oscillating machinery the unit fits a compact 150 mm seat, and in heavy industrial gearbox shafts the 42.1 kg mass is part of the rotor inertia calculation. Designers also specify it for rope drums and winch drums, relying on the 108 mm width and the published 1900 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.
