Frequently Asked Questions
Q: What is the JT PT2748W-68 ball bearing and what equipment does it fit?
A: The JT PT2748W-68 is a 14 mm diameter hardened steel ball bearing designed for Jet PT Series manual pallet jack hydraulic pump assemblies. It fits Jet model W pallet jacks and similar PT Series manual models. This is an OEM replacement part for the hydraulic pump assembly.
Q: What material and hardness specifications does this ball bearing have?
A: The JT PT2748W-68 is manufactured from SAE 52100 hardened carbon steel to DIN 5401 Grade 100 specifications. Core hardness is Rockwell C 60-66 with compressive strength of 375,000 PSI. Surface finish is polished and oil-coated to prevent corrosion.
Q: How long does this bearing typically last in service?
A: Lifespan depends on pump usage frequency and maintenance. SAE 52100 grade bearings with this hardness specification are designed for extended service life in manual pump applications. Regular inspection for wear and contamination in the pump assembly will extend bearing life. Replace if you notice rough operation or noise in the pump.
Q: Can this bearing be used as a replacement for other pallet jack brands?
A: The JT PT2748W-68 is engineered specifically for Jet PT Series pump assemblies. While other manual pallet jack brands may use similar 14 mm ball bearings, verify that the pump assembly design, bore diameter, and load specifications match before substituting. Using incorrect bearings can cause pump failure or safety hazards.
