Frequently Asked Questions
Q: What is the PR 313729-000 and what equipment does it fit?
A: The PR 313729-000 is a caster wheel assembly for BT Prime Mover SMX45 electric pallet trucks. This direct replacement unit features high-strength steel construction, polyurethane tread, and sealed ball bearing for smooth rolling and extended service life in warehouse and dock applications.
Q: What are the material specifications?
A: The PR 313729-000 features a reinforced steel caster body with integrated polyurethane wheel tread. The sealed ball bearing eliminates water and debris ingress. Polyurethane provides durable floor contact and noise reduction on warehouse concrete while maintaining factory-specification compatibility.
Q: What are the cross-reference part numbers for the PR 313729-000?
A: The PR 313729-000 is cross-referenced as PR 313729-001, PM 313729-001, PM313729-001, and 313729-001. All these numbers refer to the same caster assembly for SMX45 series equipment. Verify your equipment documentation before ordering to confirm the correct part for your application.
Q: How long does the polyurethane tread last and what indicates replacement?
A: Polyurethane caster wheels typically last 1000 to 2000 operational hours depending on floor surface, load weight, and maintenance practices. Signs of wear include visible tread reduction, flat spots, reduced steering response, or grinding noise from the bearing. Replacing worn casters improves vehicle stability and control.
Q: Can this caster assembly be used in cold storage or wet environments?
A: The sealed ball bearing and steel construction provide protection in damp warehouse environments. For extended cold storage use below 32 degrees Fahrenheit, verify material performance to ensure tread flexibility and bearing lubrication remain adequate at low temperatures.
