Frequently Asked Questions
Q: What is the JT BB-6004VV and how does it differ from the standard BB-6004?
A: The JT BB-6004VV is a double-sealed deep groove ball bearing with the same bore (20 mm), outer diameter (42 mm), and width (12 mm) as the BB-6004, but includes dual seals to protect against moisture and contamination. It replaces the older BB-6004W design.
Q: What are the exact dimensions of the JT BB-6004VV bearing?
A: The JT BB-6004VV has a 20 mm bore, 42 mm outer diameter, and 12 mm width. These dimensions match standard 6004 deep groove ball bearing specifications.
Q: What material is the JT BB-6004VV made from and how hard are the races?
A: The JT BB-6004VV is constructed from high carbon chrome steel (SAE 52100 equivalent) with hardened raceways rated at 58 to 64 HRC. This hardness provides wear resistance and long service life under load.
Q: Does the JT BB-6004VV come pre-lubricated?
A: Yes. The JT BB-6004VV comes pre-lubricated. The seals retain the original grease and help prevent outside contamination.
Q: What parts does the JT BB-6004VV replace?
A: The JT BB-6004VV replaces the older BB-6004W bearing. If you have equipment using BB-6004W, the VV version is a direct upgrade with improved sealing.
Q: When should I use the sealed JT BB-6004VV instead of the standard BB-6004?
A: Use the double-sealed JT BB-6004VV if your pallet jack operates in wet environments, cold storage, or areas with high dust and debris. The dual seals extend bearing lifespan by keeping contaminants out and grease in.
