Frequently Asked Questions
Q: What is the PR 312895-000 wheel hub and what is its construction?
A: The PR 312895-000 is a machined steel wheel hub designed as a press-on replacement component for BT Prime Mover SMX-series electric lift truck rim and hub assemblies. The hub is factory-finished with protective plating to resist corrosion and wear.
Q: What are the cross-reference and equivalent part numbers for PR 312895-000?
A: The PR 312895-000 cross-references to PM312895-000 and BT P312895-000. The manufacturer part number is PM312895-000. These are equivalent interchange parts for the same machined steel hub assembly. Verify your equipment documentation matches one of these part numbers before ordering.
Q: Which BT Prime Mover electric lift truck models use the PR 312895-000 hub?
A: The PR 312895-000 hub is designed for BT Prime Mover SMX-series electric lift trucks, including SMX 45 and related walkie pallet truck platforms. Confirm your truck model and serial range match SMX-series before ordering this hub assembly.
Q: Why is machined steel hub construction preferred for electric lift trucks?
A: Machined steel hubs provide superior strength for repeated load cycles compared to cast alternatives. The precision machining ensures precise bore concentricity and fit with wheel bearings and axles. Steel resists impact damage and maintains dimensional stability under high-speed operation on warehouse floors.
Q: What maintenance is needed to extend the lifespan of the PR 312895-000 hub?
A: Inspect the hub bore and bearing interface periodically for scoring, spalling, or corrosion. Clean debris and apply bearing lubrication according to your equipment manual. The factory corrosion-resistant finish protects against warehouse moisture and cleaning chemicals. Replace the hub if bearing bore damage is visible or if the hub cannot maintain axle alignment.
