Description
INA AY25-XL-NPP-B belongs to y-bearing (insert bearing), part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for AY25-XL-NPP-B and any equivalents.
The INA AY-XL-NPP-B series is a single-row insert bearing that mounts into split or solid housings to create a bearing unit for rotating shafts. It handles radial loads and some axial thrust, with self-aligning capability and straightforward installation.
The part number breaks down into meaningful blocks: AY denotes the insertable bearing family with a spherical outer ring; XL marks the optimized version; NPP shows double-lip seals; and B is a design variant of the inner ring. The middle number reflects the shaft size, as seen in AY12-XL-NPP-B, AY15-XL-NPP-B, AY17-XL-NPP-B, AY20-XL-NPP-B, AY25-XL-NPP-B, and AY30-XL-NPP-B. This coding lets you identify size and key features at a glance.
These Y-bearings appear in conveyors, bucket elevators, mixers, fans, centrifugal pumps, and equipment for food, textile, wood, and cement processing. They also serve in agricultural implements and packaging lines, where split housings simplify maintenance and replacement. The sealed design suits dusty, moderately humid, or splash-prone settings when paired with a suitable housing and seal.
When selecting a bearing from this series, consider shaft diameter, load type (radial, axial, or combined), environment, and speed. The NPP double-lip seal blocks contaminants and keeps lubricant in place; confirm that the housing accepts the spherical outer ring for alignment. During mounting, avoid hitting the seals and ensure the shaft is clean and free of burrs. Follow the lubrication method specified for your variant, whether life-long or relubricable.
Y-bearings are made to dimensional standards that permit interchange between brands, but tolerances, seals, and load ratings can differ. Always check the complete part number and critical dimensions before substituting one insert for another. MR Industrial Accessories supplies the INA brand within its bearing range and can advise on compatibility with other system components.

Frequently asked questions
- What does NPP indicate on an INA Y-bearing?
- NPP means the bearing has double-lip seals, which keep out contaminants and retain lubricant, making it suitable for dusty or moderately humid environments.
- How do I pick the right part number in the AY-XL-NPP-B series?
- The middle number corresponds to the shaft diameter. For instance, AY20-XL-NPP-B fits a 20 mm shaft. Verify dimensions and housing type before requesting a quote.
- Can I replace a Y-bearing from another brand with an INA one?
- Y-bearings generally follow dimensional standards that allow interchange, but tolerances, seals, and load capacity may vary. Consult our technical team on WhatsApp to confirm the equivalence.
