Frequently Asked Questions
Q: What is the UE H-1043-B139 precision steel ball used for?
A: The UE H-1043-B139 is a hardened carbon steel ball precision component used in the Uline H-1043 hydraulic pump assembly. It functions as an internal check valve component in the controlled lowering mechanism.
Q: What are the specifications for the UE H-1043-B139 steel ball?
A: The UE H-1043-B139 is manufactured from hardened carbon steel with a 3/4 inch nominal diameter. The ball features a machined and polished finish suitable for precision valve operation in oil-immersed environments.
Q: Which Uline pallet jack models use the UE H-1043-B139 steel ball?
A: The UE H-1043-B139 is designed for Uline H-1043 manual pallet jack models. Verify that your equipment uses the 3/4 inch ball size before ordering, as pump assemblies may use different ball diameters.
Q: Why is the UE H-1043-B139 ball made from hardened carbon steel?
A: Hardened carbon steel provides wear resistance and durability under high-cycle operation. The ball experiences repeated contact stress as it seats and unseats against the valve base during lifting and lowering cycles, necessitating a hard, durable material.
Q: What symptoms indicate the UE H-1043-B139 steel ball needs replacement?
A: Signs of ball wear include loss of control over lowering speed, inability to maintain a desired descent rate, oil leakage from the pump assembly, or visible pitting and scoring on the ball surface. These indicate the ball no longer seals properly in the valve seat.
