Double row full complement cylindrical roller bearings SL series are part of the group of radial roller bearings. These bearings comprise solid outer rings, inner rings and full complement rolling element sets. Due to the absence of a cage, the bearing can accommodate the largest possible number of rolling elements. The rollers have profiled ends, i.e. they have a slight lateral curvature towards the ends. This modified line contact between the rolling elements and raceways prevents damaging edge stresses. Bearings in the standard range differ essentially in the arrangement of the ribs on the inner ring and outer ring. Depending on the design, they are used as non-locating bearings, semi‑locating bearings or locating bearings.

JnSn bearings have SL series cylindrical roller bearings in stock, including full-complement cylindrical roller bearings (SL19, SL18), cylindrical roller bearings with annular slots (SL04 series), low friction cylindrical roller bearings (LSL, ZSL). These bearings are true star performers when it comes to load carrying capacity and rigidity. What most people don’t know is that they support unusually high axial loads – up to 60 percent of the radial load in fact. These bearings have a significantly longer life under axial loads and also have reduced friction thanks to the improved contact between the rollers and the ribs. This is certainly an interesting combination when considering downsizing and increasing energy efficiency.

Application

Due to their special technical features, double row full complement cylindrical roller bearings are highly suitable, for example, for bearing arrangements in heavy industry (steel production), power transmission (gearbox engineering), processing machines and construction machinery, wind turbines (gearbox applications) and so on.
