Product Description
The KO 11030-6 is a sealed ball bearing designed for manual pallet jack wheelbase and frame pivot applications. Featuring a 20mm bore diameter and 47mm outer diameter, this bearing delivers approximately 7,000 pounds of static load capacity per unit, making it ideal for 2-ton to 5-ton hand pallet jacks. The hardened alloy steel races with precision ball elements and durable rubber seal provide reliable performance across thousands of load cycles, even in wet dock and cold storage environments. Suitable for equipment from Crown, Toyota, Raymond, Yale, and Clark, the KO 11030-6 maintains dimensional stability and smooth operation under demanding warehouse conditions.
Frequently Asked Questions
Q: What is the bore size and load rating of the KO 11030-6 bearing?
A: The KO 11030-6 is a sealed ball bearing with a 20mm bore diameter and 47mm outer diameter. Load rating capacity is approximately 7000 pounds static load per bearing, which accommodates multi-ton pallet jack service. This bearing is designed for wheelbase and frame pivot applications in manual equipment.
Q: Which manual pallet jack models require the KO 11030-6 bearing?
A: The KO 11030-6 is used in manual pallet jacks from Crown, Toyota, Raymond, Yale, and Clark. Specific models include standard 2-ton, 3-ton, and 5-ton hand jacks depending on equipment generation and configuration. Verify your jack model number and serial range to confirm this bearing matches your application.
Q: Is the KO 11030-6 bearing suitable for wet or cold storage environments?
A: The sealed design of the KO 11030-6 provides protection against moisture and contamination in wet dock and cooler environments. Sealed bearings perform well in cold storage down to -4 degrees Fahrenheit. For extreme conditions or extended outdoor exposure, verify seal integrity and consider more frequent lubrication intervals to maintain performance.
Q: How do I know if my pallet jack needs a replacement KO 11030-6 bearing?
A: Replace the bearing if you hear grinding or squealing during operation, feel excessive play in the wheel axle, or notice the jack becomes difficult to move with a full load. Worn bearings also generate heat; check for hot spots on the bearing housing after operation. Early replacement prevents frame damage and maintains load control.
Q: What material composition does the KO 11030-6 have?
A: The KO 11030-6 features hardened alloy steel races with precision ball elements and a rubber seal or metal shield. The seal material resists oil degradation and temperature extremes common in warehouse operations. This construction maintains dimensional stability and rolling resistance across thousands of load cycles.
