2I7187

Frequently Asked Questions

Q: What are the specifications and dimensions of the 2I7187 bearing assembly?
A: The 2I7187 is a sealed radial ball bearing with precision ground chrome steel (SAE 52100) inner and outer rings. Bore diameter is 20mm, outer diameter is 47mm, and width is 14mm. Rubber seals provide contamination protection suitable for standard manual pallet jack wheel and axle support applications.

Q: Which pallet jack models and brands does the 2I7187 fit?
A: The 2I7187 is compatible with standard manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, and Clark that feature 20mm bore axles. It supports both load and steer wheel assemblies in warehouse pallet trucks across multiple OEM designs.

Q: How do the rubber seals on the 2I7187 compare to other bearing types?
A: The 2I7187 features rubber seals that exclude dirt, moisture, and floor debris from the bearing raceway. Sealed design provides superior contamination protection compared to open or shielded bearings, reducing maintenance intervals and extending bearing life in typical warehouse environments.

Q: What is the typical service life of the 2I7187 bearing?
A: In standard warehouse duty with regular pallet jack operation, the 2I7187 typically lasts 18 to 36 months. Life varies with floor surface conditions, equipment load cycles, and maintenance. Replace bearings if you observe wheel noise, rough rotation, excessive play, or difficulty steering.

Q: How does the 2I7187 compare to the 2I6972 bearing?
A: Both bearings share identical dimensions (20mm bore, 47mm OD, 14mm width) and are compatible with the same pallet jack applications. The 2I7187 features SAE 52100 chrome steel construction with rubber seals. Both are sealed, lubricated assemblies suitable for warehouse duty. Verify your equipment OEM specification to determine which bearing your pallet jack requires.
