Frequently Asked Questions
Q: What is the material composition of the CR 101313 seal kit?
A: The CR 101313 contains NBR (nitrile) and polyurethane elastomeric components. The nitrile elements are hardened to Shore A 70-90 specification for durability, while the polyurethane provides enhanced wear resistance in high-pressure hydraulic applications.
Q: Which Crown electric lift truck cylinders use the CR 101313?
A: The CR 101313 is designed exclusively for specific Crown cylinder assemblies. No cross-reference or superseded part numbers have been identified. Contact our technical team with your Crown equipment serial number or cylinder part number to confirm compatibility before ordering.
Q: What is the maximum working pressure for the CR 101313?
A: The CR 101313 is rated for hydraulic systems up to 3000 PSI, standard for Crown electric lift truck applications. This pressure rating applies to both dynamic and static sealing conditions typical in lift cylinder operation.
Q: Why does the CR 101313 use both nitrile and polyurethane materials?
A: NBR provides excellent resistance to petroleum hydraulic fluids and thermal stability, while polyurethane offers superior wear and extrusion resistance under high pressure cycling. The combination delivers longer service life in demanding lift truck environments.
Q: Is the CR 101313 compatible with synthetic hydraulic fluids?
A: The CR 101313 is engineered for standard petroleum-based hydraulic fluids typical in Crown systems. Before switching to synthetic fluids, verify compatibility with both the nitrile and polyurethane elastomers, as some synthetics can cause seal swelling or degradation.
