Product Introduction

The NP751516/NP317439 is a specialized non-standard tapered roller bearing engineered to precise dimensional specifications. Measuring 38.1 x 79.375 x 29.37 mm, this bearing provides high structural integrity and exceptional radial and axial load support in specialized mechanical housings where standard dimensional series do not fit. Manufactured from ultra-clean GCr15 chrome alloy steel and processed with stringent dimensional controls, the NP751516/NP317439 delivers long-term durability and smooth rotation, making it a critical solution for bespoke automotive builds and proprietary industrial drivetrains.

Applications

Proprietary automotive gearboxes and specialty transmissions.
Custom agricultural implement drives and PTO shafts.
Specialized industrial machinery and speed reducers.

FAQ

Q: Why is this considered a "non-standard" bearing?
A: It features specific dimensional modifications (indicated by the "NP" prefix) that fall outside standard ISO/ABMA inch or metric series charts, usually designed for specific OEM applications.
Q: Can you guarantee consistent supply for this non-standard size?
A: Yes, we provide reliable long-term supply contracts for B2B clients relying on specialized dimensional bearings.
