Frequently Asked Questions
Q: What are the physical dimensions of bearing cup 4TLM102910?
A: The 4TLM102910 bearing cup has an outside diameter of 2.8910 inches and a width of 0.6200 inches. These dimensions are larger than standard manual pallet jack bearings and suit electric lift truck and heavier industrial applications. Verify dimensions match your equipment before ordering.
Q: What bearing cone pairs with 4TLM102910?
A: The 4TLM102910 cup is compatible with the LM102949 bearing cone. This bearing set is designed for radial and axial load applications in electric lift truck and industrial equipment. Ensure cone and cup are ordered as a matched pair for proper bearing function.
Q: What material is 4TLM102910 made from?
A: The 4TLM102910 is manufactured from alloy steel Grade 52100 with case carburization. This material composition provides high hardness, wear resistance, and durability for heavy-duty radial and axial load applications typical of electric lift trucks.
Q: What are the cross-reference part numbers for 4TLM102910?
A: The 4TLM102910 cross-references to the OEM part number LM102910 and is equivalent to bearing cups from Timken, Koyo, SKF, Bower, and Federal-Mogul manufacturers, all designated LM102910. These cross-references provide multiple sourcing options from standard bearing suppliers.
Q: Is 4TLM102910 suitable for manual pallet jacks?
A: No. The 4TLM102910 is designed for electric lift truck applications. Its larger diameter and specifications exceed the requirements of manual pallet jacks. Manual equipment uses smaller bearing cup sizes. Confirm your equipment type and bearing specifications before purchase.
