Frequently Asked Questions
Q: What is the YL 550091339 exit roller and what is its primary function?
A: The YL 550091339 is an OEM exit roller for Yale YA55-PT series manual pallet jacks. It is positioned at the fork tip exit point and uses high-abrasion polyurethane tread with a steel core and sealed ball bearing to control pallet movement during load transfer and prevent unintended pallet pull.
Q: Which Yale manual pallet jacks are compatible with the YL 550091339 exit roller?
A: The YL 550091339 exit roller is designed for Yale YA55-PT series manual pallet jacks with 5500-pound capacity ratings. It is the direct OEM replacement part for these models and maintains the original equipment specifications for performance and durability.
Q: What are the material specifications of the YL 550091339?
A: The YL 550091339 features a high-abrasion polyurethane tread bonded to a steel core. It includes a sealed ball bearing that provides smooth rotation while protecting internal components from contamination. The polyurethane compound offers superior traction and wear resistance compared to rubber, making it ideal for heavy-duty material handling.
Q: How long does the YL 550091339 polyurethane tread typically last in service?
A: The YL 550091339 provides 20 to 40 months of reliable service in typical material handling environments, depending on load cycles, floor surface conditions, and maintenance practices. Abrasive concrete or high-frequency usage may reduce lifespan. Monitor tread wear regularly and replace when wear becomes visually significant or bearing noise develops.
Q: What inspection and maintenance practices extend the lifespan of the YL 550091339?
A: Inspect the YL 550091339 regularly for tread wear, bearing noise, and misalignment. Keep the exit roller and surrounding areas clean to prevent debris buildup that could cause bearing contamination. Monitor bearing performance and replace the sealed bearing if audible grinding or squealing occurs. Replace the entire roller assembly when tread depth decreases or mechanical failure is detected.
Q: What symptoms indicate the YL 550091339 exit roller should be replaced?
A: Replace the YL 550091339 if you observe significant polyurethane tread wear, chunks of tread missing, bearing noise or squealing, pallet slipping during exit movement, or visible misalignment of the fork tips. These conditions indicate tread degradation or bearing failure that compromises load control and equipment safety.
