How to Check a Bearing Part Number and Dimensions for a CNC Machine
Belfa Makine
When looking for a bearing for a CNC machine, start with the full manufacturer reference marked on the existing component. The NSK codes in Belfa's bearing collection are catalogue examples for comparing specifications; their presence does not establish a match to any particular machine. If the code is unclear, document both the markings and the measured dimensions of the removed bearing.
Compare bore, outside diameter, and width first. The NSK 6001ZZC3 listing records 12, 28, and 8 mm respectively, while the NSK 6003ZZC3 listing records 17, 35, and 10 mm. Similar-looking references should not replace this three-dimensional check. Keep the exact product code beside the measurements taken from the existing component.
An identical bore does not settle the comparison either. NSK 6005ZZC3 is listed with a 25 mm bore, 47 mm outside diameter, and 12 mm width. NSK 6205ZZC3 also has a 25 mm bore, but its outside diameter is 52 mm and its width is 15 mm. These catalogue examples show why checking only the bore leaves important differences unresolved.
Read the shield and radial internal clearance entries separately from the dimensions. Belfa's records for NSK 6001ZZC3 and 6205ZZC3 both specify metal shields on both sides and C3 radial internal clearance. Note the markings on the removed bearing, and avoid inferring a machine's operating requirements from a catalogue entry alone.
For an enquiry, provide the complete NSK part number, visible markings, and measured bore, outside diameter, and width. A photo or the machine's own reference can help make the enquiry precise. These listings support product identification; the final part choice still requires checking the documentation for the actual machine and removed component.
