Frequently Asked Questions
Q: What is a tapered roller bearing cup and cone assembly?
A: A tapered roller bearing cup and cone assembly is a precision-engineered rolling element bearing consisting of a separable outer race (cup) and inner race assembly (cone) with tapered raceways. The CR 805111-001 distributes radial and axial loads in drive unit and wheel assemblies of electric pallet trucks through rolling contact between the tapered surfaces.
Q: What are the key specifications of the CR 805111-001 bearing?
A: The CR 805111-001 tapered roller bearing cup and cone assembly has an inner diameter of 1.171 inches, outer diameter of 2.44 inches, and overall bearing width of 0.846 inches. These are precision dimensions for Crown ST 3000 series equipment. Verify fitment with your specific drive unit or wheel assembly bore before ordering.
Q: Which Crown equipment models does the CR 805111-001 bearing fit?
A: The CR 805111-001 tapered roller bearing is compatible with Crown ST 3000 series electric pallet jacks and stackers, for use in drive units and wheel assemblies. Confirm your equipment series designation before ordering.
Q: What materials are used in the CR 805111-001 bearing?
A: The CR 805111-001 is constructed from high carbon alloy steel for both the cup and cone races. This material composition provides the hardness, durability, and fatigue resistance required to withstand the radial and axial loading cycles typical of electric pallet truck operations.
Q: Why is a tapered roller bearing used in Crown ST 3000 series equipment?
A: Tapered roller bearings like the CR 805111-001 are used because they efficiently handle both radial and axial loads simultaneously, provide lower friction during rotation, and offer extended service life under the sustained load cycles and dynamic conditions found in electric pallet jack drive and wheel assemblies.
Q: Are there alternate part numbers or cross-references for the CR 805111-001?
A: No cross-reference part numbers are documented for the CR 805111-001. Order using the exact Crown OEM part number CR 805111-001 (alternate designation CR805111001) to ensure correct fitment in Crown ST 3000 series drive and wheel assemblies.
