The SRV.NU M series from SKF covers single-row cylindrical roller bearings that use a machined brass cage and an inner ring without flanges. They handle heavy radial loads at elevated speeds while providing only minimal axial guidance. This design suits machines where the shaft must move axially because of thermal growth, including electric motors, pumps and gearboxes.

Reading the designation helps you confirm what you are ordering. NU tells you the inner ring has no flanges while the outer ring does, so the shaft can shift axially inside the housing. The trailing M identifies a machined brass cage, which is chosen for tougher load and temperature conditions than a stamped steel cage. SRV marks the execution variant of the series. For example, SRV.NU 413 M uses the numbers to set size and load capacity within the line.

These bearings appear in rotating equipment such as medium and large electric motors, centrifugal pumps, industrial fans, gearboxes and machine tools. Conveyors and mills also use them where radial loads are heavy and speeds stay high. Because the bearing is separable, mounting and dismounting during maintenance is easier, particularly on large-diameter shafts or where access is limited.

Selection depends on radial load, speed and lubrication method. The SRV.NU M series works with grease or oil; for high-speed duty, oil and a suitable heat removal arrangement are preferred. Sealing should match the environment: add external seals or protectors in dusty or damp locations. Shaft-to-housing alignment matters because angular misalignment beyond the permissible limit reduces bearing life. Check internal clearance before mounting and set it according to the fit.

Interchangeability is possible between makers of single-row cylindrical roller bearings with a flangeless inner ring when main dimensions, tolerances and clearance agree. A similar part number is not enough: compare bore, outer diameter, width and load capacity. Even M-suffix series from other manufacturers may use a brass cage, yet internal geometry can differ. Always check the original manufacturer's tables or ask for technical support before substituting.
