Decoding NSK 1319 K
- 13Series
- Self-aligning ball bearings, 13 series. Series differ in outside diameter and width even when the bore is the same.
- 19Bore
- Bore 95 mm (19 × 5).
- KSuffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
1319 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NSK 1319 K measures 95 mm across the bore and 200 mm across the outside diameter; its width is 45 mm (95 x 200 x 45 mm).

When shafts flex or alignment between shaft and housing is not perfect, a double-row self-aligning ball bearing with a tapered bore can keep the assembly running. The NSK K series covers this need. It is common in fans, pumps, conveyors and agricultural equipment. MR Industrial Accessories supplies this series and helps you match the right part number to your application.
Reading the part number is straightforward once you know the code. The basic number comes first, and the K at the end signals a tapered bore. Take 1204 K, 1205 K or 1206 K: each is a self-aligning ball bearing with a tapered bore diameter. That K suffix tells you the bearing mounts on a tapered shaft or with an adapter sleeve. Without the K, the bore is cylindrical. If you are unsure which version your equipment uses, MR can help you confirm.
These bearings suit equipment where misalignment or shaft flex occurs: industrial fans, centrifugal pumps, conveyors, mixers, agricultural machinery and belt drives. They are also common in the food, chemical and cement industries and in aggregate processing plants. The self-aligning design compensates for angular deviation, which helps reduce wear and extend the life of the assembly. MR Industrial Accessories supplies them for replacement and maintenance work.
Selection depends on load, speed and how the bearing is mounted. For the K series with tapered bore, check the shaft taper or plan for an adapter sleeve, and verify the locking method. Lubrication and sealing matter just as much: pick the lubricant for your operating temperature and environment, and add seals where dust or moisture is present. Even though the bearing tolerates misalignment, initial alignment still pays off. MR can help you work through these points.
NSK K series bearings can be interchanged with other brands that use the same dimensional designation. To find an equivalent, compare bore, outer diameter and width, and confirm the bore type is tapered. If you have a part number from another brand, MR will point you to the corresponding NSK reference. Interchangeability is common among catalog bearings, but always check tolerances and internal clearance.

Frequently asked questions
- NSK 1319 K bearing: what are its dimensions?
- NSK 1319 K 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 1319.
- What does the K indicate in the bearing designation?
- A K means the bearing has a tapered bore. It mounts on a tapered shaft or with an adapter sleeve, which makes adjustment and removal easier. Check the shaft taper or use the correct adapter sleeve.
- Where are K series self-aligning ball bearings used?
- They are found in equipment where shafts can become misaligned, such as fans, pumps, conveyors and agricultural machinery. The self-aligning feature compensates for small angular deviations and helps reduce wear in demanding industrial applications.
- How do I request a quote for an NSK K series bearing?
- Send the complete bearing part number, for example 1205 K, by WhatsApp and we will quote it promptly. If you do not have the part number, provide the shaft and housing dimensions or the equipment model and we will advise you.
