Cylindrical roller bearings in the NTN SL series are built for equipment that carries substantial radial loads at moderate running speeds. The cylindrical roller and steel cage arrangement suits tough industrial duty, which is why these bearings turn up in heavy machinery and transmission systems where load capacity and precision both matter. MR supplies them by part number or size.

Reading the code helps you narrow down the right unit. The letters SL mark the high-capacity cylindrical roller family, and the digits that follow describe the internal design and dimensions. Take SL01-4830: it belongs to the SL01 execution and has a 150 mm bore. SL02-4848 is the SL02 variant with a 240 mm bore. The numeric suffix is what pins down the exact size and version.

You will find these bearings in steel, cement, mining and agricultural machinery manufacturing. Gearboxes, conveyor belts, mills and material handling equipment commonly use them. Heavy radial loads and resistance to contamination make them a fit for harsh plant environments.

Selection comes down to radial load, rotation speed and the conditions on site. Check whether the application calls for seals or shields, since SL series bearings can come either way. Proper alignment at mounting and correct lubrication, grease or oil, are what let the bearing reach its expected service life. Follow the manufacturer's guidance on fitting and cleanliness.

Bearings in the NTN SL series can be exchanged with equivalents from other makers when dimensions and tolerances match. If your part number comes from a different brand, send it over and we will identify the NTN equivalent. Cage type and technical specifications affect interchangeability, so each case needs checking.
