Deep Groove Ball Bearings SKF 6301 -2Z

The SKF 6301-2Z deep groove ball bearing, measuring 12x37x12 mm, offers compact dimensions, dust protection on both sides and low-friction operation for standard applications.

The SKF 6301-2Z single-row deep groove ball bearing is a versatile rolling bearing designed primarily for radial loads. By virtue of its design, it can also accommodate moderate axial forces in both directions. Manufactured from standard 100Cr6 bearing steel in the SKF Explorer performance class, the bearing features a dimensionally stable sheet steel cage to guide the rolling elements. The outer ring, which has no flange or groove, allows for installation in cylindrical housing bores.

What requirements does the 6301-2Z deep groove ball bearing meet in operation?

The bearing is primarily used in designs where combined forces occur and compact installation dimensions are required. With a bore of 12 mm, an outer diameter of 37 mm and a width of 12 mm, the component meets common mechanical requirements. The permissible temperature range is from –20 to +120 degrees Celsius. The version with standard radial clearance is suitable for standard fit conditions without extreme thermal expansion.

What are the benefits of the -2Z cover plates on both sides?

The suffix ‘-2Z’ denotes non-contact gap seals made from profiled sheet steel covers on both sides of the bearing. These cover plates keep solid contaminants and dust out of the bearing interior and reduce lubricant leakage. As the sheet metal discs do not come into contact with the rotating inner ring, no additional frictional resistance is generated during operation. The 6301 -2Z deep-groove ball bearing starts up with low torque and is suitable for applications involving higher speeds.
