Frequently Asked Questions
Q: What are the dimensions of bearing L9503003546?
A: Bearing L9503003546 has an inside diameter of 20 mm, outside diameter of 47 mm, and width of 14 mm. These dimensions fit standard wheel and load roller designs on manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and similar manufacturers. Verify your equipment bore and housing specifications match before ordering.
Q: What material is bearing L9503003546 made from?
A: L9503003546 is constructed from SAE 52100 chrome steel with hardness rated Rockwell C58–C62. This material provides exceptional strength, wear resistance, and load capacity for demanding manual pallet jack applications. The chrome steel raceways resist corrosion and maintain precision under high load cycles.
Q: Is bearing L9503003546 sealed against moisture and contamination?
A: Yes. L9503003546 features dual synthetic seals that protect the bearing from dust, moisture, and contamination. This sealed design enables maintenance-free operation and extends bearing life in warehouse and cold storage environments. The seals are not serviceable, so if compromised, the entire assembly must be replaced.
Q: What load capacity does bearing L9503003546 handle?
A: L9503003546 is engineered for high load capacity suitable for manual pallet jack wheel and load roller applications. The 20 mm bore and SAE 52100 chrome steel construction support the dynamic loads generated during normal pallet truck operation. Consult your equipment manufacturer specifications to confirm this bearing meets your load requirements.
Q: How do I know if bearing L9503003546 needs replacement?
A: Replace L9503003546 if you experience grinding or clicking noises from the wheel or load roller, rough rotation, excessive play or wobbling, or resistance to movement. These symptoms indicate bearing wear or seal failure. Once seals fail, water and contamination enter the bearing and cause premature failure.
