Frequently Asked Questions
Q: What are the specifications for the 6204LLBNR bearing?
A: The 6204LLBNR is an NTN deep groove ball bearing with a 20 mm bore diameter, 47 mm outside diameter, and 14 mm width. It features high carbon chrome steel construction, pressed steel cage, and double nitrile rubber contact seals. Dynamic load capacity is 12,800 N with C3 internal clearance and ABEC 1/ISO P0 precision grade.
Q: What is the maximum rotational speed for the 6204LLBNR?
A: The 6204LLBNR has a maximum rotational speed of 10,000 RPM. This bearing is rated for general industrial applications requiring sealed bearing protection and axial retention capability via the external snap ring groove on the outer race.
Q: What seal material is used in the 6204LLBNR?
A: The 6204LLBNR uses nitrile rubber (NBR) contact seals on both sides. These double seals provide protection against contamination while maintaining low friction during operation.
Q: Does the 6204LLBNR have an external snap ring groove?
A: Yes, the 6204LLBNR features an external snap ring groove on the outer race, which provides axial retention capability. This design allows for secure mounting in applications requiring positive axial positioning.
Q: What is the cage construction material in the 6204LLBNR?
A: The 6204LLBNR uses a pressed steel cage construction. This cage design supports the rolling elements and is suitable for general industrial bearing applications.
