How the SL024964 model number is decoded

envelope 320×440×118 mm with a 60.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1700 kN and C0 4050 kN; with a C/C0 ratio of 0.42 the 118 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 435 kN, the limiting speed 800 r/min and the thermal reference speed 395 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 5.31 kN per millimetre of the 320 mm bore and 14.41 kN per millimetre of the 118 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 54.9 kg (54900 g) (1.06 g per mm² of the 440×118 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 320 mm bore this is among the largest catalogue sizes; the 800 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position SL0249 is the double-row full-complement non-locating (floating) bearing: the flangeless outer ring moves freely over the rollers, taking only radial load while a separate bearing locates the shaft Typical applications include vibrating and oscillating machinery, heavy industrial gearbox shafts and rope drums and winch drums, where the 440 mm outside diameter and 1700 kN dynamic rating match the duty. In vibrating and oscillating machinery the unit fits a compact 320 mm seat, and in heavy industrial gearbox shafts the 54.9 kg mass is part of the rotor inertia calculation. Designers also specify it for rope drums and winch drums, relying on the 118 mm width and the published 4050 kN static rating. 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.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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.
• 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.
