Frequently Asked Questions
Q: What are the specifications of the JT PT2748A-040 steel ball?
A: The JT PT2748A-040 is a precision-ground 14 mm hardened steel ball manufactured to bearing-grade standards. It is designed for use in the hydraulic unit of Jet manual pallet jacks as a check or valve component. The ball is engineered for durability and repeatable pressure cycling in hydraulic assemblies.
Q: Which Jet pallet jack models use the JT PT2748A-040?
A: The JT PT2748A-040 is compatible with Jet manual pallet jacks in the A, L, and J model series, including the PT2748A model. The part functions as a check ball or valve ball in the hydraulic lift assembly. Verify your model designation on the equipment nameplate before ordering.
Q: What cross-reference part numbers are equivalent to JT PT2748A-040?
A: Cross-reference numbers for the JT PT2748A-040 include JTPT2748A-040, PT2748A-040, and Jet PT2748A-040. The variant PT2748A-040A may apply to certain Jet A, L, and J series applications. Confirm the exact part number from your equipment documentation or contact us for verification.
Q: How long does a hardened steel ball typically last in a pallet jack hydraulic system?
A: Bearing-grade hardened steel balls in hydraulic check valve assemblies typically last the operational life of the pallet jack if operated normally and maintained properly. Premature wear or replacement may indicate contamination in the hydraulic fluid, worn seals, or metal debris from other components. If check balls require frequent replacement, investigate the source of contamination in the hydraulic assembly.
