The INA PNA-XL series is a radial needle roller bearing that combines an inner ring, an outer ring and a needle cage. It is built for applications where radial space is tight but radial loads are significant. MR Industrial Accessories LLC supplies this series as part of its INA bearing range for customers in the United States and Latin America.
Reading the part number helps you confirm the size before ordering. In a designation such as PNA12/28-XL, PNA15/32-XL or PNA20/42-XL, the letters PNA indicate a needle roller bearing with both rings. The first number is the bore diameter and the second is the outer diameter, separated by a slash. The XL suffix marks the current INA generation, which brings design updates without changing the mounting dimensions.
These bearings are common in machine tools, transmission equipment, pumps, compressors and material handling systems. They also appear in automotive, agricultural and mining machinery, where a small radial section must carry a heavy radial load. Gearboxes, pulleys and rollers are typical installation points.
When selecting a PNA-XL bearing, start with the bore and outer diameter your application requires, then check the load and speed conditions. Support alignment and lubrication matter: grease or oil may be used depending on the working environment. In dusty or humid areas, add extra protection at the seal. Use the correct mounting tools to avoid damaging the rings and needles.
INA needle roller bearings can be replaced by products from other European manufacturers that follow the same dimensional standards, such as SKF, FAG or NTN, provided the dimensions and execution type match. Tolerances and load capacity should still be checked for each maker. Our team can help you identify a suitable equivalent for your equipment.

Frequently asked questions
- What does the XL suffix mean on an INA bearing?
- It identifies the current INA generation. Design updates are included, but the mounting dimensions stay the same, so it can replace earlier versions.
- How do I pick the right PNA-XL bearing?
- Note the required bore and outer diameter, plus the working loads and speeds. Match those to the part number. If you are unsure, send us the dimensions and we will help.
- Can PNA-XL bearings be swapped with other brands?
- Yes, if the dimensions and execution type follow the same international standards. SKF, FAG and NTN offer equivalents. Check tolerances and capacities before replacing.
