Frequently Asked Questions
Q: What are the dimensions of the TO 00591-64390-81 bearing?
A: The TO 00591-64390-81 is a deep groove ball bearing with a 35.25 mm bore, 80.00 mm outer diameter, and 21.00 mm width. It is manufactured by JTEKT Japan and specified for Toyota electric lift truck applications, particularly in transfer case assemblies.
Q: What does C4 radial clearance mean for this bearing?
A: C4 radial clearance indicates a larger internal clearance specification than standard C0. This clearance level is designed for applications requiring greater space between rolling elements and races, providing better accommodation for thermal expansion and shaft deflection in electric lift truck transfer case systems.
Q: Is the TO 00591-64390-81 an open type bearing?
A: Yes, the TO 00591-64390-81 is an open type bearing, meaning it has no seals or shields. This design allows direct contact with the surrounding environment and requires external protection from contamination. Verify that your application includes appropriate sealing if exposure to moisture or debris is a concern.
Q: What is the cage material for this bearing?
A: The TO 00591-64390-81 features a steel cage, which provides durability and strength in industrial material handling equipment. Steel cages are common in load-bearing bearing applications where reliability and service life are critical.
Q: Which Toyota electric lift truck models use the TO 00591-64390-81?
A: This bearing is specified for Toyota electric lift truck applications, particularly in transfer case assemblies. Verify your specific model and year against the OEM part number 00591-64390-81 before ordering to confirm compatibility with your equipment.
Q: What is the typical service life of the TO 00591-64390-81 bearing?
A: Service life depends on operating conditions, load levels, and maintenance practices. Open type bearings require regular monitoring for wear and contamination. Schedule replacement if you observe increased noise, vibration, or temperature rise in the transfer case assembly.
