Frequently Asked Questions
Q: What is the 00591-35808-81 bearing assembly used for?
A: The 00591-35808-81 is a Toyota OEM bearing assembly designed for electric lift truck mast assemblies. This bearing is engineered to support the mast column during fork elevation and lowering cycles in powered pallet jack operation. The bearing must handle both radial and axial loads from the load being lifted.
Q: What equipment models does the 00591-35808-81 fit?
A: The 00591-35808-81 is specified for Toyota electric pallet jack series equipment. Before ordering, verify your equipment model number and serial range against Toyota specifications. Using this bearing on non-Toyota electric lift equipment without dimensional verification will result in fitment failure.
Q: How does electric lift truck operation affect bearing performance?
A: Electric lift trucks operate with powered mast raise and lower, creating continuous load cycling at controlled speeds. This results in consistent bearing loads compared to manual jacks where operator technique varies. The 00591-35808-81 is designed for the duty cycle typical of electric lift trucks, typically 5 to 10 raises per minute in normal warehouse service.
Q: What bearing material does the 00591-35808-81 use?
A: The 00591-35808-81 uses case-hardened bearing steel, which provides high surface hardness combined with a tough core. This material composition allows the bearing to withstand repeated impact loads and shock that occur when the mast stops and reverses direction. Case-hardened construction provides superior spalling resistance compared to unhardened steel.
Q: Is there a cross-reference or equivalent part for the 00591-35808-81?
A: The 00591-35808-81 is a Toyota OEM part number with no listed cross-reference SKUs. If you need a bearing for non-Toyota electric lift equipment, contact us with your mast channel bore diameter, outside diameter, width, and load specifications for compatibility assessment.
