YL 507380800

Frequently Asked Questions

Q: What is the YL 507380800 ball bearing and what does it do in an electric lift truck?
A: The YL 507380800 is a Yale OEM single shield ball bearing designed for electric lift truck applications. This component supports rotating axles, mast components, or drive systems under load. The single shield design provides protection from light contamination while maintaining low friction and smooth operation. Verify your equipment model and bearing location match before ordering.

Q: What are the dimensional specifications and load rating of the YL 507380800?
A: Exact bore diameter, outer diameter, width, and dynamic load rating are determined by the specific bearing model. The YL 507380800 is engineered for forklift bearing assembly duty cycles and load conditions. Consult the Yale parts diagram or contact technical support with your equipment model number to confirm precise dimensions and load specifications.

Q: Can the YL 507380800 single shield bearing be used in wet or dusty environments?
A: The single shield design provides basic sealing against light splash and dust. However, in wet storage facilities, dock environments, or heavy dust conditions, the bearing can accumulate moisture or contamination, leading to rust and premature failure. For harsh environments, verify whether a double shield or sealed bearing variant is available for your application.

Q: What are the signs that the YL 507380800 bearing needs replacement?
A: Common failure symptoms include grinding or squealing noises from the bearing location, rough rotation, excessive axle play or wobbling, and overheating. If you observe any of these symptoms during operation, the bearing has likely lost preload or internal balls are damaged. Replacement prevents secondary damage to axles and surrounding components.

Q: How do I verify that a replacement bearing is compatible with the YL 507380800 specification?
A: Bearing compatibility requires exact matching of bore diameter, outer diameter, width, shield configuration, and load rating. Aftermarket or equivalent bearings must meet the same dimensional and performance specifications. Verify the cross-reference part number against your equipment documentation. Using an undersized or lower-rated bearing will cause premature failure.

Q: What is the typical service life of the YL 507380800 bearing?
A: Service life depends on operating conditions, load patterns, lubrication maintenance, and environmental exposure. In moderate warehouse service, Yale OEM bearings typically last 3 to 5 years or longer. Exposure to moisture, contamination, or continuous high-load cycles shortens lifespan. Regular inspection and prompt replacement extends overall equipment reliability.
