Frequently Asked Questions
Q: What is the CR 045752 and where does it fit on a Crown pallet jack?
A: The CR 045752 is an OEM Crown load roller assembly for manual pallet jacks. It is a complete roller assembly featuring a 3-inch outside diameter, 3.75-inch tread width, and is press-fit with a sealed ball bearing. This assembly functions as a load wheel mounted to the fork tines and supports the pallet load during lifting and movement.
Q: What are the material and finish specifications for the CR 045752?
A: The CR 045752 is constructed from SAE 1045 medium carbon steel and features a zinc plating finish for corrosion resistance. SAE 1045 is a medium-carbon steel selected for its balance of strength and toughness in load-bearing applications. The zinc plating protects the steel from rust and extends component lifespan in humid or wet warehouse environments.
Q: What is the bore size of the CR 045752, and why does this matter?
A: The CR 045752 has a 0.875-inch bore for axle mounting. This bore size must match your existing axle diameter precisely. If your pallet jack uses a different axle size, the CR 045752 will not fit. Verify your current load wheel bore dimension before ordering to ensure proper fitment.
Q: What type of bearing is used in the CR 045752?
A: The CR 045752 features a sealed ball bearing integrated into the roller assembly. Sealed bearings are pre-lubricated and enclosed to prevent contamination from dust, dirt, and moisture in warehouse environments. This design reduces maintenance requirements and extends bearing life compared to open or grease-packed bearing designs.
Q: Will the CR 045752 fit Crown manual pallet jacks other than the PTH50?
A: The CR 045752 is designed as a replacement load roller for Crown manual pallet jacks. However, fitment depends on your specific Crown model. Verify that your pallet jack has a 3-inch diameter roller requirement, a 0.875-inch axle bore, and a 3.75-inch tread width. If your model has different load roller dimensions, this part will not be compatible.
