The NTN SL series cylindrical roller bearing handles high radial loads at moderate speeds. Its cylindrical rollers and steel cage suit tough industrial environments. You will find it in heavy machinery, mining equipment, conveyors and transmission systems that demand rigidity and durability. MR Industrial Accessories supplies this series to customers across the United States and Latin America.

The part number tells you what you are holding. SL marks the high-capacity cylindrical roller bearing family. The following digits give size and design variant. SL04 is a defined design with standardized dimensions. NR means the outer ring has a groove and a retaining ring for axial mounting. Sizes run from SL04-5008NR through SL04-5015NR.

These bearings show up in mining equipment, cement and crushing plants, conveyors and agricultural machinery. They also work in gearboxes, transmission shafts, support rollers, cranes and material handling equipment. When a machine runs under severe conditions, this series is a common replacement choice.

Selection starts with radial load, speed and the working environment. The SL series is usually mounted with an interference fit on the shaft and in the housing to prevent slipping. Check alignment between shaft and support. Lubrication can be grease or oil, depending on the application. Sealing depends on dust or moisture; in contaminated areas, add extra protection.

SL series cylindrical roller bearings can be interchanged with equivalent products from other brands when main dimensions and tolerances match. Compare bore, outer diameter and width, plus load capacity. If you have a part number from another brand, MR Industrial Accessories will identify the compatible alternative. We can also quote the exact size you need.
