594A

BEARING

The 594A is a tapered roller bearing cone (inner ring) used in two-piece tapered roller bearing assemblies. It mates with a matching cup to support combined radial and thrust loads in heavy-duty truck and trailer wheel hubs. This cone is part of a wheel-end bearing set that allows the wheel to rotate smoothly while handling the weight of the vehicle. Replace when bearings show signs of wear, pitting, noise, or overheating, typically during routine brake or wheel-end service.
