Frequently Asked Questions
Q: What is a DU-type self-lubricating composite bushing?
A: The CR 42053-008 is a DU-type bushing with a steel backing and PTFE/lead sliding layer. This composite construction provides self-lubrication without requiring external lubricants, reducing maintenance needs and friction in high-load applications.
Q: What are the material specifications of the CR 42053-008?
A: The CR 42053-008 features a low-carbon steel backing with a PTFE/lead composite sliding layer. The wear layer thickness ranges from 0.010 to 0.020 inch. This construction provides high static and dynamic load capacity suitable for electric lift truck pivot applications.
Q: What is the load capacity of the CR 42053-008?
A: The CR 42053-008 is engineered for high static and dynamic load capacities. The PTFE/lead composite material distributes loads effectively across the bearing surface. For specific load ratings, consult the Crown equipment specification or contact technical support.
Q: How long does the wear layer last on a CR 42053-008?
A: The wear layer thickness of 0.010 to 0.020 inch is designed for extended service life under continuous operation. Actual lifespan depends on load, cycle frequency, and operating conditions. The self-lubricating PTFE/lead composite reduces wear compared to plain sleeve bushings.
Q: Which Crown equipment uses CR 42053-008 bushings?
A: The CR 42053-008 is engineered for electric lift truck and electric pallet jack lift structures, including Crown GPW Series equipment. Verify your specific model and lift structure design before ordering to ensure fitment.
