Frequently Asked Questions
Q: What are the specifications of the YL 500193907 sintered bronze bushing?
A: The YL 500193907 is a sintered bronze self-lubricating plain bearing with an inner diameter of 0.75 inches and outer diameter of 1.0 inch, manufactured to ANSI/SAE 841 standards. Verify shaft and bore dimensions match before ordering.
Q: What Yale lift truck applications use the YL 500193907?
A: The YL 500193907 is engineered for lift linkage and pivot points on Yale electric lift trucks. Cross-reference part numbers include 12DU16, YT500193907, and older designations 5001939-20 and 500193920. Confirm your equipment requires this specific bore and shaft size.
Q: Why is sintered bronze preferred for lift truck bushings?
A: Sintered bronze is self-lubricating, porous, and impregnated with oil that releases during operation. This design reduces friction, extends service life, requires minimal maintenance, and provides consistent performance under the repetitive loading and pivot motion in lift truck linkage systems.
Q: What should I do if the YL 500193907 bushing makes noise?
A: Noise indicates wear, inadequate lubrication, or excessive shaft play. Sintered bronze bushings are self-lubricating but can wear thin over time. If noise persists after confirming correct installation fit, replacement is necessary to restore smooth mast operation and prevent linkage damage.
