Frequently Asked Questions
Q: What are the dimensions and bearing specifications for the CR 81645-035 load wheel?
A: The CR 81645-035 features an 8-inch diameter wheel with a 2.5-inch hub width and 20 mm bore. It is equipped with precision-sealed 6204 ball bearings rated for continuous load handling. Confirm your equipment bore size and hub width before ordering this assembly.
Q: Which Crown equipment models does the CR 81645-035 fit?
A: The CR 81645-035 is designed for Crown SX3000 Series, WP Series, and WS Series electric lift trucks. Verify your model number against the compatible series list. Cross-references include CR 81645-025, CR 81645-030, CR 81645-040, and CR 81645-A.
Q: What is the core material and tread composition of the CR 81645-035?
A: The CR 81645-035 has a polyurethane 95A tread bonded to a cast iron core. This construction combines flexibility in the tread with rigidity and weight distribution from the cast iron foundation. Cast iron cores provide superior load capacity compared to aluminum or composite hubs.
Q: What other part numbers are equivalent to the CR 81645-035?
A: The CR 81645-035 supersedes CR 81645-025 and CR 81645-030. It is equivalent to CR 81645-040 and CR 81645-A. Confirm that bore diameter, hub width, and wheel diameter match before substituting these part numbers on your equipment.
Q: What sealed bearing type is used in the CR 81645-035 and why does it matter?
A: The CR 81645-035 uses 6204 sealed ball bearings, a standard size across material handling equipment. Sealed bearings keep out dust, moisture, and contaminants common in warehouse floors, extending bearing life and reducing friction. Sealed bearings require no regular lubrication, lowering maintenance overhead.
Q: What maintenance intervals should I follow for the CR 81645-035 wheel assembly?
A: Inspect wheels quarterly for tread wear, flat spots, and bearing noise. Sealed bearings do not require greasing. Monitor bearing play by checking for side-to-side movement at the wheel rim. Replace the wheel if tread depth is visibly reduced, bearings feel rough or make noise, or the wheel is visibly cracked.
