How the SL183024 model number is decoded

envelope 120×180×46 mm with a 30.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 295 kN and C0 425 kN; with a C/C0 ratio of 0.69 the 46 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 59 kN, the limiting speed 2,160 r/min and the thermal reference speed 1,840 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 2.46 kN per millimetre of the 120 mm bore and 6.41 kN per millimetre of the 46 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 3.8 kg (3800 g) (0.46 g per mm² of the 180×46 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads with a 120 mm bore this is a heavy-industrial bearing: 3.8 kg of stiff ring and roller set, specified where rigidity matters more than speed The dimension-series digits place this bearing in the SL18 section of the HR1 plan, giving the 30.0 mm section height between the 120 mm bore and the 180 mm outside diameter High radial rigidity at 295 kN C is the point of this design: rib-guided rollers in a cageless pack resist deflection in planetary gears, rope drums and vibrating machinery Typical applications include vibrating and oscillating machinery, heavy industrial gearbox shafts and rope drums and winch drums, where the 180 mm outside diameter and 295 kN dynamic rating match the duty. In vibrating and oscillating machinery the unit fits a compact 120 mm seat, and in heavy industrial gearbox shafts the 3.8 kg mass is part of the rotor inertia calculation. Designers also specify it for rope drums and winch drums, relying on the 46 mm width and the published 425 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.
• 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.
