How the SL014928 model number is decoded

envelope 140×190×50 mm with a 25.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 270 kN and C0 550 kN; with a C/C0 ratio of 0.49 the 50 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 1,950 r/min and the thermal reference speed 1,370 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.93 kN per millimetre of the 140 mm bore and 5.40 kN per millimetre of the 50 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 4.2 kg (4200 g) (0.44 g per mm² of the 190×50 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 140 mm bore this is among the largest catalogue sizes; the 1,950 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position No angular compensation is built in: misalignment loads one roller row preferentially, so the housing and shaft seats for a 140 mm bore SL0149 must be machined parallel SL0149 is the double-row full-complement locating bearing: it supports the radial load and axial loads in both directions, fixing the shaft axially at that position Typical applications include compact slow-speed agitator drives, planetary gear bearing positions and crane travelling-wheel mechanisms, where the 190 mm outside diameter and 270 kN dynamic rating match the duty. In compact slow-speed agitator drives the unit fits a compact 140 mm seat, and in planetary gear bearing positions the 4.2 kg mass is part of the rotor inertia calculation. Designers also specify it for crane travelling-wheel mechanisms, relying on the 50 mm width and the published 550 kN static rating. C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.

Selection pitfalls — read before you substitute

• C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
• Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
• 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.
