How the SL182212-XL model number is decoded

envelope 60×110×28 mm with a 25.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 169 kN and C0 176 kN; with a C/C0 ratio of 0.96 the 28 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 33 kN, the limiting speed 3,900 r/min and the thermal reference speed 2,550 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 2.82 kN per millimetre of the 60 mm bore and 6.04 kN per millimetre of the 28 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 1.18 kg (1180 g) (0.38 g per mm² of the 110×28 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 60 mm bore this is a mainstream industrial size — conveyor drives, winches and medium gearboxes use the 28 mm width as a standard mounting space High radial rigidity at 169 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 SL182212-XL is a single-row full-complement cylindrical roller bearing: no cage is fitted, so the maximum number of rollers runs between the rings, and the rollers guide themselves on the two inner-ring ribs As an X-life (-XL) bearing it benefits from the optimised surface finish that reduces friction and raises the fatigue strength behind the 33 kN Cur value. Typical applications include heavy industrial gearbox shafts, crane travelling-wheel mechanisms and vibrating and oscillating machinery, where the 110 mm outside diameter and 169 kN dynamic rating match the duty. In heavy industrial gearbox shafts the unit fits a compact 60 mm seat, and in crane travelling-wheel mechanisms the 1.18 kg mass is part of the rotor inertia calculation. Designers also specify it for vibrating and oscillating machinery, relying on the 28 mm width and the published 176 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.
• 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.
