Frequently asked questions about 6011
What does the open design mean on a 6011 bearing?
The 6011 (55mm x 90mm x 18mm) is supplied open — without seals or shields — so lubrication and relubrication come from the surrounding housing or an external system. Compare seal types before deciding on the replacement.
Which part numbers are equivalent to 6011?
Equivalent designations include 011 . These are brand-specific numbers for the same ISO boundary dimensions as the 6011 (55mm x 90mm x 18mm). The basic number matching does not confirm the complete specification — compare seal type, clearance, precision, cage, and lubrication suffix before ordering.
Does the 6011 come with C3 clearance?
This directory lists the 6011 with CN (Standard). C3 (increased internal clearance) versions are common for higher operating temperatures, higher speeds, or press-fit arrangements — specify the required clearance on your RFQ so the quotation matches the application. Read the clearance guide.
The 6011 is listed as a 55×90×18mm deep groove ball bearing in open configuration. Part of the 6000 series, the directory records chrome steel gcr15 and P0 (ABEC-1) precision grade for RFQ verification.
The 6011 uses the same part number designation across SKF, FAG, NSK, NTN, and Timken catalogs. This is a standardized deep groove ball bearing with industry-standard boundary dimensions. Confirm the housing style, shaft diameter, and seal type before ordering a replacement.
About the 6000 Series
The 6000 series is an extra light duty deep groove ball bearing series designed for applications requiring compact dimensions and high-speed capability. These bearings offer lower load capacity than the 6200 series but excel where space and weight are constrained.
