How the SL014926 model number is decoded

envelope 130×180×50 mm with a 25.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 260 kN and C0 510 kN; with a C/C0 ratio of 0.51 the 50 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 64 kN, the limiting speed 2,090 r/min and the thermal reference speed 1,500 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 2.00 kN per millimetre of the 130 mm bore and 5.20 kN per millimetre of the 50 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 3.95 kg (3950 g) (0.44 g per mm² of the 180×50 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 130 mm bore, 180 mm outside diameter: at this size the 510 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs 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 Inside the 130×180×50 mm envelope the two cageless rows provide C0 510 kN, the capacity this series is selected for in heavy gearbox and drum positions Typical applications include heavy industrial gearbox shafts, crane travelling-wheel mechanisms and vibrating and oscillating machinery, where the 180 mm outside diameter and 260 kN dynamic rating match the duty. In heavy industrial gearbox shafts the unit fits a compact 130 mm seat, and in crane travelling-wheel mechanisms the 3.95 kg mass is part of the rotor inertia calculation. Designers also specify it for vibrating and oscillating machinery, relying on the 50 mm width and the published 510 kN static rating. 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.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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.
• Use the rib structure correctly: SL18/SL1850 give one-direction axial guidance, SL0149 locates both ways and SL0249 floats — pairing two locating bearings on one shaft binds thermal growth.
