Frequently Asked Questions
Q: What are the dimensions and specifications of the HY 43307 bearing?
A: The HY 43307 is a single-shielded deep groove ball bearing with a 35 mm bore, 80 mm outside diameter, and 21 mm width. It is manufactured from chrome steel with high-carbon composition for durability in electric lift truck applications.
Q: What are the cross-reference part numbers for the HY 43307?
A: The HY 43307 is equivalent to the standard 6307 ball bearing. Alternate references include 43307W and 43307-P, which may be listed in some catalogs as superseding or replacing models.
Q: Which Hyster electric lift trucks use the HY 43307 bearing?
A: The HY 43307 is designed for Hyster electric lift truck assemblies. Verify the bearing cavity dimensions (35 mm bore and 80 mm OD) match your specific lift truck model before ordering.
Q: What material is the HY 43307 bearing made from?
A: The HY 43307 uses chrome steel construction with high-carbon composition, providing superior hardness and wear resistance for the radial and thrust load demands of electric lift truck operations.
Q: Is the HY 43307 bearing single or double shielded?
A: The HY 43307 is single shielded, meaning one side has a protective shield. This design allows access to the bearing interior for lubrication while reducing contamination ingress.
