Frequently Asked Questions
Q: What is the 00591-35817-81 bearing assembly?
A: The 00591-35817-81 is a Toyota OEM bearing assembly engineered for electric lift truck mast operation. This bearing supports the mast channel during powered fork lift and lower cycles, managing both radial and axial loads generated by the lifted load and mast motion.
Q: What is the application and equipment compatibility for the 00591-35817-81?
A: The 00591-35817-81 is designed for Toyota electric pallet jack and electric lift truck mast assemblies. Verify your equipment model and serial range match Toyota specifications before ordering. Fitment depends on mast channel bore diameter, outside diameter, and bearing width dimensions.
Q: What loads does the 00591-35817-81 support in electric lift truck service?
A: The 00591-35817-81 is manufactured to withstand combined radial loads from the lifted load pressing down on the mast channel, plus axial loads from the powered mast raise and lower mechanism. In electric lift truck operation, the bearing experiences continuous cycling at controlled hydraulic or motor speeds, typically 5 to 12 lift cycles per minute.
Q: What material is the 00591-35817-81 constructed from?
A: The 00591-35817-81 uses case-hardened bearing steel for the races and rolling elements. Case hardening creates a hard exterior surface that resists wear and spalling, while the core remains tough to absorb impact from sudden mast deceleration. This material provides extended service life under the repeated load reversals typical of electric lift truck mast operation.
Q: Are there alternative or cross-reference part numbers for the 00591-35817-81?
A: The 00591-35817-81 is a Toyota OEM part with no available cross-reference SKUs. If you require this bearing for equipment other than Toyota electric lift trucks, contact us with your mast specifications including bore diameter, outside diameter, width, and load capacity requirements.
