Frequently Asked Questions
Q: What are the dimensions and specifications of bearing L5520001306?
A: Bearing L5520001306 is a precision ball bearing with 20 mm bore diameter, 47 mm outside diameter, and 14 mm width. It features dual-side rubber seals, arrives pre-lubricated, and conforms to ISO 492 ABEC 1 class dimensional and tolerance standards. These dimensions fit manual pallet jack wheel axle assemblies using 20 mm shafts.
Q: Which manual pallet jack models use bearing L5520001306?
A: Bearing L5520001306 is compatible with manual pallet jacks from common manufacturers including Crown, Toyota, Raymond, Yale, Hyster, and similar equipment with 20 mm axle shaft specifications and 47 mm wheel hub bores. Verify the exact bore and outside diameter of your equipment before ordering.
Q: What does ISO 492 ABEC 1 classification mean?
A: ISO 492 ABEC 1 is an international precision standard for ball bearing dimensions and tolerances. ABEC 1 is the lowest precision grade, appropriate for material handling equipment. This classification ensures the bearing meets standard dimensional tolerances and performs reliably in pallet jack wheel applications.
Q: Does bearing L5520001306 need lubrication?
A: Bearing L5520001306 arrives pre-lubricated and sealed. No additional lubrication is required for normal warehouse operation. The dual rubber seals retain internal grease and protect against contamination. Do not force additional lubricant into sealed units as this can degrade performance.
Q: How long does bearing L5520001306 last?
A: Sealed pre-lubricated bearings like L5520001306 typically operate for 3-7 years in active manual pallet jack service. Lifespan depends on load cycles, operating temperature, and environmental contamination. Wet or chemically aggressive environments reduce bearing life. Replace when you notice rough rotation or excessive play.
