Decoding NSK N 319
- N 3Series
- Cylindrical roller bearings, N 3 series. Series differ in outside diameter and width even when the bore is the same.
- 19Bore
- Bore 95 mm (19 × 5).
N 319 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NSK N 319 measures 95 mm across the bore and 200 mm across the outside diameter; its width is 45 mm (95 x 200 x 45 mm).

Cylindrical roller bearings in the NSK N series are built for machines that run under heavy radial load at considerable speed. The parallel raceways and cylindrical rollers keep operation precise where radial forces dominate. You will find them in industrial machinery, electric motors, pumps and transmission equipment. MR Industrial Accessories supplies this series and can help you match the right size to your equipment.
Reading the code helps you confirm what you are ordering. The N tells you the outer ring has no flange, so the bearing can accommodate relative axial movement. The digits that follow, as in N 211, N 212 or N 216, set the size and tie back to bore diameter and load capacity, with larger numbers meaning larger diameter and capacity. Suffixes can point to cage, tolerance or heat treatment differences, so check the full part number before you commit.
These bearings show up across many industries. Large electric motors, gearboxes, centrifugal pumps, industrial fans and mining equipment are common homes for them. You will also see them in food, cement and steel operations where radial loads are demanding. Their capacity for high speed and load suits gear transmissions and shafts of large diameter. MR Industrial Accessories supplies them for replacement and maintenance work.
When selecting a bearing, weigh the radial load, the rotation speed and the surrounding conditions. The N series does not take meaningful axial load, so pair it with another bearing if forces in that direction are present. Mounting calls for precise alignment between shaft and housing, plus proper lubrication, grease or oil as the application requires. Sealing depends on the environment; in contaminated areas, add extra protection. Follow the manufacturer's instructions for mounting and lubrication.
Interchange is possible between N series cylindrical roller bearings from different makers when the main dimensions and design line up. NSK, SKF, FAG, NTN and Timken all offer comparable series, but you must verify the full part number and tolerances, because suffixes are not always compatible across brands. For a replacement, compare dimensions and operating conditions first. MR Industrial Accessories can help you identify the right option.

Frequently asked questions
- NSK N 319 bearing: what are its dimensions?
- NSK N 319 measures 95 mm across the bore and 200 mm across the outside diameter; its width is 45 mm (95 x 200 x 45 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation N 319.
- What does the N series mean in NSK bearings?
- The N stands for a cylindrical roller bearing with a flangeless outer ring, which permits axial displacement. The numbers after it define size and load capacity. It is a series made for high radial loads.
- Where are NSK N series bearings used?
- They appear in electric motors, pumps, gearboxes, fans and industrial equipment that sees significant radial loads. Cement, steel and food plants are typical settings.
- How do I request a quote for an NSK N series bearing?
- Send the complete part number or the bearing dimensions via WhatsApp or email. MR Industrial Accessories will quote promptly and point out a compatible alternative if one is needed.
