How the SL192334-TB-BR model number is decoded

envelope 170×360×120 mm with a 95.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1830 kN and C0 2380 kN; with a C/C0 ratio of 0.77 the 120 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 270 kN, the limiting speed 1,200 r/min and the thermal reference speed 730 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 10.76 kN per millimetre of the 170 mm bore and 15.25 kN per millimetre of the 120 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 59.2 kg (59200 g) (1.37 g per mm² of the 360×120 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 170 mm bore puts this execution at the top of the HR1 range — the 360 mm outside diameter, 120 mm width and 59.2 kg mass are built for primary-industry load cases SL192334-TB-BR is the wide dimension-series 23 execution of the single-row full-complement principle: a markedly wider 120 mm ring carries more and longer rollers than the 29/30-series sizes The 120 mm width versus 360 mm outside diameter gives this series its characteristic squat proportions and high tipping rigidity under eccentric loads Reading -TB: Schaeffler's enhanced-rib design for full-complement bearings; axial friction torque is reduced while radial ratings stay at 1830 kN C. The -BR coating is a handling and storage protection; once mounted and greased, the 360 mm bearing operates to its normal 1,200 r/min limit. Typical applications include rope drums and winch drums, vibrating and oscillating machinery and marine and offshore winch arrangements, where the 360 mm outside diameter and 1830 kN dynamic rating match the duty. In rope drums and winch drums the unit fits a compact 170 mm seat, and in vibrating and oscillating machinery the 59.2 kg mass is part of the rotor inertia calculation. Designers also specify it for marine and offshore winch arrangements, relying on the 120 mm width and the published 2380 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.
