Frequently Asked Questions
Q: What material is the PM 01.01 load roller bracket made from?
A: The PM 01.01 bracket is manufactured from SAE 1045 carbon steel with oil-impregnated bronze bushings per ASTM B438 specification. This combination provides strength for heavy loads while allowing smooth rotation of the load roller.
Q: Which pallet jack models use the PM 01.01 bracket?
A: The PM 01.01 Load Roller Bracket with Bushings is designed for Palletmaster models PML4000 and PML5000. It is rated for 5000 lbs load capacity at a 24 inch load center. Confirm your model designation before ordering.
Q: What are the critical dimensions of the PM 01.01 bracket?
A: The bracket has a 0.75 inch bore diameter for the load roller pin, a 7/16 inch mounting hole diameter, and a 3.25 inch center-to-center hole spacing for frame attachment. These dimensions are specific to Palletmaster PML4000 and PML5000 equipment.
Q: What does the oil-impregnated bronze bushing provide?
A: Oil-impregnated bronze bushings (ASTM B438) provide self-lubricating properties, reducing friction on the load roller pin. This extends bushing life and reduces maintenance compared to un-lubricated bushings, especially under continuous load cycles.
Q: What load capacity does the PM 01.01 bracket support?
A: The PM 01.01 bracket is rated for 5000 lbs load capacity at a 24 inch load center. This rating applies to Palletmaster PML4000 and PML5000 models. Load capacity depends on correct installation and equipment condition.
Q: Why is SAE 1045 carbon steel used for this bracket?
A: SAE 1045 carbon steel is a mid-range steel that balances strength with machinability. It provides the load-bearing strength required for heavy pallet handling while allowing precise manufacturing of the bore and mounting holes to tight tolerances.
