Frequently Asked Questions
Q: What are the key dimensions and load ratings for the EC BB1-6304Z bearing?
A: The EC BB1-6304Z is a single row deep groove ball bearing with a 20 mm bore diameter, 52 mm outside diameter, and 15 mm width. It is rated for 1780 lbf dynamic load and 3950 lbf static load. Maximum operating speed reaches 14,000 RPM with grease lubrication or 17,000 RPM with oil lubrication.
Q: What material is the EC BB1-6304Z bearing constructed from?
A: The EC BB1-6304Z features a high carbon chromium steel bearing race with ISO Class 0 precision. The cage is constructed from pressed steel, and the bearing includes a single metal shield for debris protection in industrial material handling environments.
Q: Which pallet jack models does the EC BB1-6304Z bearing fit?
A: The EC BB1-6304Z bearing is designed for manual pallet jacks made by Ecoa. Verify your equipment model number and bearing dimensions match before ordering to ensure proper fitment.
Q: How does the metal shield affect bearing performance and maintenance?
A: The single metal shield provides protection against dirt and contamination in warehouse and loading dock environments. The shielded design requires less frequent cleaning than open bearings but does restrict access for re-greasing. Monitor for noise or resistance increases as an indicator that replacement is needed.
