Frequently asked questions about 6300-ZZ
What does the open design mean on a 6300-ZZ bearing?
The 6300-ZZ (10mm x 35mm x 11mm) 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 6300-ZZ?
Equivalent designations include 6300-2Z, 6300-2ZR, 6300ZZ, 300ZZ, 6300Z, 6300ZZS . These are brand-specific numbers for the same ISO boundary dimensions as the 6300-ZZ (10mm x 35mm x 11mm). The basic number matching does not confirm the complete specification — compare seal type, clearance, precision, cage, and lubrication suffix before ordering.
Does the 6300-ZZ come with C3 clearance?
This directory lists the 6300-ZZ 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 6300-ZZ is listed as a 10×35×11mm deep groove ball bearing in double metal shielded configuration. Part of the 6300 series, the directory records chrome steel gcr15 and P0 (ABEC-1) precision grade for RFQ verification.
The 6300-ZZ bearing cross-references to SKF 6300-2Z, FAG 6300-2ZR, NSK 6300ZZ and NTN 6300ZZ. This means you can replace an SKF equivalent, FAG alternative, NSK cross reference, or NTN interchange part with the same ISO boundary dimensions. Compare the full specification table and designation suffixes before ordering, especially the seal type (2RS vs ZZ) and internal clearance (C3 vs CN).
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
