Frequently Asked Questions
Q: What Crown equipment models are compatible with the CR 77086-1-A?
A: The CR 77086-1-A tandem polyurethane load wheel assembly fits Crown PE 3000 Series and Crown PW Walkie electric pallet jacks. The assembly features sealed ball bearings and compound 305 Durarun polyurethane for enhanced durability in heavy-duty applications.
Q: What cross-reference part numbers are equivalent to the CR 77086-1-A?
A: The CR 77086-1-A replaces 77086-A and is compatible with CR77086-A. It supersedes the older 77086-301 designation and is equivalent to CR77086-20. Verify the correct cross-reference for your equipment model before ordering.
Q: What is compound 305 Durarun and why is it used in the CR 77086-1-A?
A: Compound 305 Durarun is a premium-grade polyurethane material engineered for extended tread life in demanding warehouse environments. It resists rapid wear, maintains consistent rolling resistance, and provides superior load distribution across sealed ball bearings. This compound delivers harder, more durable performance than standard alternatives.
Q: How do sealed ball bearings improve the CR 77086-1-A performance?
A: Sealed ball bearings reduce contamination from dust, moisture, and warehouse debris. This design extends bearing service life, reduces rotational friction, and requires minimal maintenance compared to open bearing designs. Sealed bearings provide more consistent wheel performance over extended operating periods.
Q: What is the expected service life of the CR 77086-1-A wheel?
A: The compound 305 Durarun material and sealed bearing design typically deliver 3000 to 6000 operating hours in heavy-duty warehouse use. Actual lifespan varies based on floor surface conditions, total load weight, and daily cycle frequency. Inspect wheels regularly for bearing play, flat spots, or tread wear.
Q: What storage conditions are recommended for the CR 77086-1-A?
A: Store wheels indoors in a dry location away from direct sunlight, extreme heat, and ozone sources. Keep sealed bearings clean and protect the polyurethane surface from harsh chemicals, oils, and solvents that may degrade the material.
