Frequently Asked Questions
Q: What equipment does the 00591-06446-81 bearing assembly fit?
A: The 00591-06446-81 single-shield bearing assembly is compatible with manual pallet jacks from multiple OEM manufacturers including Toyota, Crown, Raymond, and Yale. This bearing is used in load wheel housings and pivot assemblies rated for standard 5,500 lb capacity jacks. Verify your equipment model and serial range before ordering to confirm fitment.
Q: What is the shipping unit for the 00591-06446-81?
A: The 00591-06446-81 bearing assembly comes packaged 10 per sleeve and 100 per box. This bulk packaging is standard for parts distributors and high-volume maintenance operations. Verify your order quantity matches your equipment volume and replacement schedule.
Q: Why is the single-shield design used on the 00591-06446-81?
A: Single-shield bearings provide protection on one race while leaving the opposite side open for load and mounting access. This design is ideal for pivot and load wheel applications where the bearing must accept radial loads while maintaining tight steering response. The exposed side allows for easier inspection and maintenance compared to fully sealed designs.
Q: What material is the 00591-06446-81 bearing made from?
A: The 00591-06446-81 uses precision-ground bearing steel with hardened races and high-carbon ball elements. This material composition provides the durability and precision needed for load wheel and pivot duty under repeated cycling at rated working loads. The hardened steel resists wear and maintains tight tolerances throughout the bearing service life.
Q: How long does the 00591-06446-81 bearing last in normal operation?
A: Under normal indoor warehouse operation with routine maintenance, the 00591-06446-81 typically delivers 2 to 4 years of service life depending on daily usage intensity and operating conditions. Load wheel bearings wear faster than pivot bearings due to rolling contact. Replace the bearing immediately if you observe noise, grinding, lateral play, or resistance to rotation during operation.
Q: What is the replacement procedure for the 00591-06446-81?
A: Bearing replacement requires removing the load wheel or pivot assembly from the jack, pressing or driving out the old bearing, and pressing the new 00591-06446-81 into the bore. Use a bearing puller and press to avoid damaging the housing. Do not strike or force-fit the bearing by hand. Apply light grease around the bearing bore before installation and verify the bearing rotates freely before reinstalling the wheel or pivot assembly.
