Frequently Asked Questions
Q: What are the dimensions and specifications of the KO 49910-02 bearing?
A: The KO 49910-02 is a 20mm bearing with two rubber shields designed for manual pallet jack load wheel and support assemblies. The rubber shields provide contamination protection on both bearing faces, making it suitable for environments where dust or moisture exposure is a concern.
Q: Which pallet jack models is the KO 49910-02 bearing compatible with?
A: The KO 49910-02 is an OEM component for Komatsu manual pallet jack models. Verify your equipment model number and load wheel bearing size against the Komatsu parts compatibility documentation to confirm the KO 49910-02 is the correct replacement for your pallet jack.
Q: What is the purpose of the rubber shields on the KO 49910-02?
A: The two rubber shields on the KO 49910-02 protect the bearing races from contamination including dirt, water, and particulates. This sealed design extends bearing life, especially in wet or dusty warehouse and loading dock environments where manual pallet jacks operate.
Q: Is the KO 49910-02 better than the KO 49910-01 for my application?
A: The KO 49910-02 differs from the KO 49910-01 in two ways: it is 20mm in diameter and includes two rubber shields for added protection. The KO 49910-02 is recommended if your pallet jack specifications call for a sealed bearing or if you operate in wet, cold, or heavily contaminated environments. Always verify bearing diameter and seal requirements before ordering.
Q: How do I maintain the KO 49910-02 bearing with rubber shields?
A: Sealed bearings like the KO 49910-02 require minimal maintenance. Inspect the rubber shields periodically for tears or separation. If shields are damaged, contamination can enter the bearing races. Replace the bearing if shields show signs of deterioration or if the bearing develops noise or play in the wheel assembly.
Q: What is the service life of the KO 49910-02 bearing?
A: The rubber shields extend service life by protecting bearing races from water and dirt. Typical service life depends on pallet jack usage frequency and environmental conditions. Bearings with intact shields can last significantly longer than unshielded designs in wet or cold storage environments.
