Frequently Asked Questions
Q: What are the exact dimensions and material composition of bearing 602134100?
A: This is a deep groove ball bearing with 20 mm bore, 47 mm outer diameter, and 14 mm thickness. It is manufactured from SAE 52100 high-carbon chromium alloy steel with double nitrile rubber seals for protection against contaminants and moisture.
Q: Which manual pallet jack brands are compatible with the 602134100 bearing?
A: This bearing is compatible with load and steer wheel assemblies on manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Daifuku, Clark, and other major manufacturers. Verify that your equipment has a 20 mm wheel bore diameter before ordering.
Q: Why is SAE 52100 chrome steel used in this bearing?
A: SAE 52100 is a high-carbon chromium alloy steel selected for superior durability and load capacity. This material resists wear under heavy pallet loads and maintains hardness in warehouse environments, significantly extending bearing service life in both load and steer wheel applications.
Q: How do the double rubber seals protect this bearing?
A: Double nitrile rubber seals on both sides prevent contaminant entry, moisture infiltration, and grease loss. The sealed design is ideal for wet dock areas, outdoor storage, and high-dust warehouse environments where manual pallet jacks operate regularly.
Q: What is the expected service life and when should this bearing be replaced?
A: In typical heavy-use warehouse conditions, expect 2-3 years of service life. Replace this bearing if you detect grinding sounds from the wheel, feel binding or resistance when rotating the wheel by hand, observe seal damage, or notice leakage around the bearing.
