Frequently Asked Questions
Q: What is the PM312170-000 bearing cup used for?
A: The PM312170-000 is a tapered roller bearing cup (outer race) used in manual pallet jack wheel and steering axle assemblies. It works with a matching bearing cone to support radial and thrust loads.
Q: Which pallet jack models use the PM312170-000 bearing cup?
A: The PM312170-000 is compatible with manual pallet jacks from Crown, Toyota, Raymond, and Yale. Confirm your equipment model and bearing bore size before ordering to ensure correct fitment.
Q: What material is the PM312170-000 made from?
A: The PM312170-000 bearing cup is manufactured from case-hardened steel with precision ground raceways. This provides wear resistance and durability in high-load manual pallet jack applications.
Q: How do I know if my PM312170-000 bearing cup needs replacement?
A: Replace the bearing cup if you observe noise, grinding sounds, or uneven wheel wear. A damaged cup can cause wheel wobble, steering issues, and accelerated wear on the mating bearing cone.
Q: Do I need to replace both the cup and cone together for the PM312170-000?
A: It is recommended to replace bearing cups and cones as matched pairs. If you are replacing only the cup, have the mating cone inspected for damage. Mismatched new and worn bearings will not perform correctly.
