Frequently Asked Questions
Q: What is the CR 77084-003-A and what equipment does it fit?
A: The CR 77084-003-A is a polyurethane load wheel assembly for Crown electric pallet trucks, compatible with Crown PR 3000 Series models with riser assemblies. It is designed for tandem and dual wheel configurations on the fork assembly. The wheel includes factory-installed sealed bearings and comes ready to mount.
Q: What are the exact dimensions and bore specifications for CR 77084-003-A?
A: The CR 77084-003-A has a 3.25 inch outside diameter, 3.25 inch tread width, and 25 mm bore diameter. It includes 6205-2RS sealed ball bearings pre-installed. The polyurethane tread is bonded to a cast iron core, providing durability in repetitive load wheel cycling environments.
Q: What cross-reference part numbers apply to the CR 77084-003-A?
A: The CR 77084-003-A cross-references include CR77084, 77084, 317084, 317084-003, 77084-003, 77084-001, 77084-002, 77084-302, 77084-305, 77084-401, 82740, and 317084-001. It also supersedes 092537S-020, 092537S-025, 092537S-10, and 092537S variants. Verify dimensions match your equipment before ordering under a cross-reference number.
Q: Why does the CR 77084-003-A include pre-installed sealed bearings?
A: The 6205-2RS sealed bearings come factory-installed on the CR 77084-003-A to reduce assembly time and ensure proper bearing seating. The sealed design (2RS) shields the bearing from warehouse dust and moisture, extending bearing life under typical Crown electric pallet truck duty conditions. The bearing does not require pre-installation or bearing press work at point of use.
Q: How long does the CR 77084-003-A typically last in service?
A: Load wheel lifespan depends on floor conditions, load frequency, and maintenance. The polyurethane tread and sealed bearing design on the CR 77084-003-A are suitable for standard indoor warehouse use. Regular inspection for tread wear and bearing noise is recommended. Replace the wheel when tread becomes thin, uneven, or the bearing develops excessive play or noise.
Q: Can the CR 77084-003-A be used on wet or cold storage floors?
A: The standard 95A polyurethane tread on the CR 77084-003-A is optimized for dry to damp warehouse floors. Performance may be reduced on wet or icy surfaces due to lower grip. For cold storage (below 32 degrees Fahrenheit) or wet floor environments, consult load wheel alternatives with specialized tread compounds designed for those conditions.
