Frequently Asked Questions
Q: What are the exact dimensions of the CR 088628-040 load wheel?
A: These dimensions are critical for fitment verification on Crown electric pallet trucks. The shoulder bearing configuration supports the wheel on the axle assembly.
Q: What polyurethane compound is used in the CR 088628-040?
A: The CR 088628-040 features a 92A durometer polyurethane compound, which provides a moderately firm tread with good load support and resistance to deformation. A 92A compound offers improved floor grip and shock absorption while maintaining structural integrity for heavy-duty electric lift truck and pallet jack use.
Q: Are there alternative compound options for the CR 088628-040 base part number?
A: Yes. The CR 088628 base part number has variants with different durometer ratings. A 95A Shore hardness variant exists and may be specified under different suffix codes. Check the variant part numbers 088628-402-88 and 088628-035-HL to compare available compound options, as hardness selection affects traction and wear characteristics.
Q: What does the shoulder bearing configuration mean?
A: The shoulder bearing design uses a bearing race pressed onto the axle shoulder to support the wheel radially. This configuration is common on Crown electric pallet trucks and handles both the wheel weight and side loads from turning and steering operations.
Q: How do I determine if the CR 088628-040 is compatible with my equipment?
A: Verify that your Crown electric pallet truck equipment has an axle and accepts wheels. Check your equipment's parts manual or contact Crown directly to confirm the wheel specifications match before ordering.
Q: What is the product lifespan and when should the CR 088628-040 be replaced?
A: Polyurethane load wheels typically last 12-24 months depending on usage intensity, floor conditions, and load weight. Replace the wheel when tread wear becomes visible, when flat spots develop, or when bearing play becomes excessive during operation.
