Frequently Asked Questions

Q: What are the specifications of bearing assembly 03040-06306?
A: The 03040-06306 is a precision sealed ball bearing with a 20 mm bore diameter, 47 mm outside diameter, and 14 mm width. It features dual rubber contact seals and is rated for load capacities up to 5000 lbs. The bearing is constructed from high-carbon chromium steel for strength and wear resistance.

Q: Which manual pallet jack models use the 03040-06306 bearing assembly?
A: The 03040-06306 fits multiple manual pallet jack models from Crown, Toyota, Raymond, Yale, and other major material-handling equipment manufacturers. The standard 20 x 47 x 14 mm bore and outside diameter configuration is common across many platforms. Verify your equipment serial number and model against the bearing dimensions before ordering.

Q: What is the load capacity of bearing 03040-06306?
A: This bearing assembly is rated for applications up to 5000 lbs. The high-carbon chromium steel construction and dual rubber contact seals provide durability for typical warehouse manual pallet jack loads. Do not exceed the rated capacity, as this will accelerate bearing wear and failure.

Q: How do the dual rubber seals on the 03040-06306 improve performance?
A: The dual rubber contact seals exclude dirt, moisture, and debris from entering the bearing races, extending bearing life significantly. This sealed design reduces maintenance and allows the bearing to operate reliably in typical warehouse, outdoor, and loading dock environments without frequent re-greasing.

Q: What is the expected service life of the 03040-06306 bearing assembly?
A: Under normal warehouse conditions with typical manual pallet jack usage, this sealed bearing should provide 3 to 5 years of service. Life depends on load frequency, environmental conditions, and proper mounting. Replace immediately if the bearing makes grinding or squealing noises or shows noticeable play in the wheel.
