How the SL014922 model number is decoded

envelope 110×150×40 mm with a 20.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 198 kN and C0 400 kN; with a C/C0 ratio of 0.49 the 40 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 51 kN, the limiting speed 2,500 r/min and the thermal reference speed 1,600 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.80 kN per millimetre of the 110 mm bore and 4.95 kN per millimetre of the 40 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 2.15 kg (2150 g) (0.36 g per mm² of the 150×40 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 110 mm bore the 150 mm outside diameter and 40 mm width target rolling stands, construction machinery and heavy gearboxes; the limiting speed drops to 2,500 r/min The locating structure has an axially split outer ring with ribs on both sides, joined by retaining rings, and an inner ring with a centre rib — the 40 mm width houses two complete roller rows The outer ring carries an annular lubrication groove and holes, so the 198 kN dynamic rating can be maintained with relubrication without dismounting the 2.15 kg unit Typical applications include hydraulic pumps and radial piston pumps, marine and offshore winch arrangements and rolling-mill and steel-industry drives, where the 150 mm outside diameter and 198 kN dynamic rating match the duty. In hydraulic pumps and radial piston pumps the unit fits a compact 110 mm seat, and in marine and offshore winch arrangements the 2.15 kg mass is part of the rotor inertia calculation. Designers also specify it for rolling-mill and steel-industry drives, relying on the 40 mm width and the published 400 kN static rating. The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling. C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.

Selection pitfalls — read before you substitute

• The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
• C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
• 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.
