How the SL014980 model number is decoded

envelope 400×540×140 mm with a 70.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 2310 kN and C0 5800 kN; with a C/C0 ratio of 0.40 the 140 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 610 kN, the limiting speed 650 r/min and the thermal reference speed 300 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 5.78 kN per millimetre of the 400 mm bore and 16.50 kN per millimetre of the 140 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 96.5 kg (96500 g) (1.28 g per mm² of the 540×140 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 400 mm bore this is among the largest catalogue sizes; the 650 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position 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 As the fixed (locating) bearing it takes the thermal-expansion thrust from the shaft while the paired floating bearing moves; the limiting speed here is 650 r/min Typical applications include rope drums and winch drums, vibrating and oscillating machinery and marine and offshore winch arrangements, where the 540 mm outside diameter and 2310 kN dynamic rating match the duty. In rope drums and winch drums the unit fits a compact 400 mm seat, and in vibrating and oscillating machinery the 96.5 kg mass is part of the rotor inertia calculation. Designers also specify it for marine and offshore winch arrangements, relying on the 140 mm width and the published 5800 kN static rating. The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling. 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.

Selection pitfalls — read before you substitute

• The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
• 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.
• 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.
