Decoding NSK N 313W
- N 3Series
- Cylindrical roller bearings, N 3 series. Series differ in outside diameter and width even when the bore is the same.
- 13Bore
- Bore 65 mm (13 × 5).
- WSuffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
N 313 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NSK N 313W measures 65 mm across the bore and 140 mm across the outside diameter; its width is 33 mm (65 x 140 x 33 mm).

For maintenance and purchasing teams working with high-radial-load, high-speed rotating equipment, the NSK N series cylindrical roller bearing is a common specification. These single-row bearings use cylindrical rollers guided by a pressed steel cage, which supports uniform load distribution and high rigidity. You will find them in machine tools, electric motors, and power transmission equipment. MR Industrial Accessories supplies this series to customers across the United States and in several Latin American countries, and can help you confirm the correct part number for your application.
The part number itself tells you most of what you need to know. Take N 204W: the N means a single-row cylindrical roller bearing with two ribs on the inner ring and none on the outer ring, so the bearing can allow axial displacement. The digits that follow set the size, and the W suffix identifies a pressed steel cage. In the same way, N 205W and N 206W cover different shaft diameters. Reading the code correctly is the first step in matching a replacement to the equipment on your floor.
These bearings show up in gearboxes, pumps, fans, compressors, and machine tools, across sectors such as metalworking, food processing, mining, and power generation. Their construction suits continuous-duty equipment that combines heavy radial loads with elevated speeds. Maintenance workshops and machinery builders both rely on the N series for that combination.
Selection comes down to three inputs: the radial load the application applies, the rotational speed, and the operating environment. At installation, shaft-to-housing alignment needs to be precise, and lubrication must be correct, whether grease or oil is specified. The pressed steel cage contributes strength and stable running. Check internal clearance and the fits on the shaft and in the housing as part of the job, since these points affect wear and service life.
On interchangeability, bearings that follow the same international designation, including products from SKF, FAG, or NTN, can serve as equivalents when dimensions and tolerances match. Confirm the complete part number and the technical data before you substitute a part. If anything is unclear, our team can help you work through the options for your equipment.
