Frequently asked questions about 6313
What does the open design mean on a 6313 bearing?
The 6313 (65mm x 140mm x 33mm) 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 6313?
Equivalent designations include 313 . These are brand-specific numbers for the same ISO boundary dimensions as the 6313 (65mm x 140mm x 33mm). The basic number matching does not confirm the complete specification — compare seal type, clearance, precision, cage, and lubrication suffix before ordering.
Does the 6313 come with C3 clearance?
This directory lists the 6313 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 6313 is listed as a 65×140×33mm deep groove ball bearing in open configuration. Part of the 6300 series, the directory records chrome steel gcr15 and P0 (ABEC-1) precision grade for RFQ verification.
The 6313 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 6300 Series
The 6300 series is a medium duty deep groove ball bearing with higher load ratings than the 6200 series. With a thicker cross-section (larger OD and width for the same bore), these bearings handle heavier radial loads and are commonly found in larger motor frames and industrial gearboxes.
Common Applications
- Heavy Machinery
- Mining Equipment
- Steel Mills
- Industrial Gearboxes
