Frequently Asked Questions
Q: What are the specifications of the 6206Z bearing?
A: The 6206Z is an ISO-standardized deep groove ball bearing with 30mm bore, 62mm outside diameter, and 16mm width. It features chrome steel construction with hardened high carbon content, a single non-contact metal shield, pressed steel cage, ISO P0 precision, dynamic load rating of 20,500 N, static load rating of 11,300 N, and is designed for radial load applications.
Q: What is the maximum speed rating for the 6206Z?
A: The 6206Z has a mechanical speed limit of 18,000 RPM maximum, which is significantly higher than sealed bearing variants. The single metal shield design allows minimal drag and permits sustained high-speed operation. The fatigue load limit is 510 N under continuous operation.
Q: How does the metal shield on the 6206Z compare to rubber seals?
A: The 6206Z uses a single non-contact metal shield rather than rubber seals. Metal shields provide excellent speed capability and lower drag but offer minimal contamination protection compared to sealed bearings. Choose 6206Z only for clean, dry environments. Wet or dusty conditions require sealed variants like 6206RS or 6206RS2.
Q: What equipment types use the 6206Z bearing?
A: The 6206Z bearing fits electric pallet jacks, high-speed load wheel assemblies, and other material handling equipment from Crown, Toyota, Raymond, Yale, and similar brands where speed performance and radial load capacity are critical. Verify your equipment specifications match before ordering.
Q: Why is the load capacity of 6206Z higher than sealed 6206 variants?
A: The 6206Z has a dynamic load capacity of 20,500 N compared to lower ratings on sealed variants. Open-design bearings like the 6206Z optimize ball and race geometry for load support without seal space constraints. However, this advantage applies only in clean environments; contamination ingress would quickly damage the unshielded design.
