Product Description
The YL 550090854 thrust plate is a load-bearing component designed for Yale manual pallet jacks. This hardened steel plate distributes load evenly and reduces friction between rotating and stationary wheel assembly components, extending equipment life and maintaining smooth operation. The thrust plate supports the axle under load while preventing lateral movement, ensuring stable, even tire wear and safe load handling across all floor surfaces.
Frequently Asked Questions
Q: What is the YL 550090854 thrust plate and what does it do?
A: The YL 550090854 is a thrust plate (also called a load bearing plate or thrust washer) that distributes load and reduces friction between rotating and stationary components in the wheel assembly. It supports the axle and wheel under load and prevents sideways movement during operation.
Q: Which manual pallet jack models use the YL 550090854 thrust plate?
A: The YL 550090854 is an OEM Yale component for the YA55-PT manual pallet jack and compatible Yale models. Verify compatibility with your equipment serial number before ordering.
Q: What material is the thrust plate made from and why does that matter?
A: Yale thrust plates are manufactured from hardened steel or bronze-bearing materials. These materials withstand high contact pressure, reduce wear on the axle, and maintain consistent dimensional tolerances under continuous load cycles typical in material handling environments.
Q: How can I tell if the thrust plate is worn out and needs replacement?
A: Signs of thrust plate wear include excessive vertical play in the wheel assembly, lateral shifting of the wheel on the axle, rough rolling motion, or grinding sounds during operation. A worn thrust plate reduces load stability and can cause uneven tire wear.
Q: Is the YL 550090854 a consumable part with a typical service life?
A: The thrust plate is a wear item. Lifespan depends on load applied, floor conditions, and operation frequency. In moderate-duty environments, expect 2000 to 5000 operating hours before measurable wear occurs. High-load or rough-floor operations may reduce service life significantly.
