How the SL192313-XL model number is decoded

envelope 65×140×48 mm with a 37.5 mm radial section; every available circumferential space carries a roller because there is no cage C is 350 kN and C0 345 kN; with a C/C0 ratio of 1.01 the 48 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 67 kN, the limiting speed 3,200 r/min and the thermal reference speed 2,180 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 5.38 kN per millimetre of the 65 mm bore and 7.29 kN per millimetre of the 48 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 3.52 kg (3520 g) (0.52 g per mm² of the 140×48 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 65 mm bore the 140 mm outside diameter and 48 mm width target rolling stands, construction machinery and heavy gearboxes; the limiting speed drops to 3,200 r/min The 48 mm width versus 140 mm outside diameter gives this series its characteristic squat proportions and high tipping rigidity under eccentric loads Large SL1923 sizes in HR1 are typically the TB design with oxide-finished surfaces; the 3.52 kg mass reflects the thick, deformation-resistant rings As an X-life (-XL) bearing it benefits from the optimised surface finish that reduces friction and raises the fatigue strength behind the 67 kN Cur value. Typical applications include compact slow-speed agitator drives, planetary gear bearing positions and crane travelling-wheel mechanisms, where the 140 mm outside diameter and 350 kN dynamic rating match the duty. In compact slow-speed agitator drives the unit fits a compact 65 mm seat, and in planetary gear bearing positions the 3.52 kg mass is part of the rotor inertia calculation. Designers also specify it for crane travelling-wheel mechanisms, relying on the 48 mm width and the published 345 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.
