Cage materials — Deep Groove Ball Bearing

Suffix	Material	Printed by
`(none)`	Pressed steel	NSK, NTN, Timken
`M / MA / MB`	Machined brass	SKF, Schaeffler (FAG), Timken
`TN9 / TVP / TVH`	Polyamide (glass-fibre reinforced PA66)	SKF, Schaeffler (FAG)
`PH`	PEEK	SKF

Suffix letters are set by each manufacturer; the third column names the brands that print the row. Always confirm the exact variant in the manufacturer's table.

Clearance groups

Group	Meaning
`C2`	Radial internal clearance smaller than normal
`CN`	Normal clearance — the ISO default group, usually not printed in the designation (SKF/FAG may write it as CN or C0)
`C3`	Radial internal clearance greater than normal
`C4`	Greater than C3

CN is the ISO normal clearance group and is usually not printed in the designation; other groups include C2, C3 and C4. The numeric ranges are defined per bearing type and size (ISO 5753), so always compare them in the manufacturer's table.

Bearing materials

Material	Where it appears
Bearing steel	Rings and rolling elements — the standard for every model without a special material note
Stainless steel	Corrosion-resistant versions, e.g. the SKF "W" series
Ceramic rolling elements (hybrid)	Ceramic balls or rollers running in steel rings; electrically insulating and tolerant of poor lubrication
Ceramic-coated steel rings	SKF INSOCOAT: VL0241 coats the outer ring, VL2071 the inner ring (electrical insulation against stray currents)

The material refers to the rings and the rolling elements. Unless a special material is stated, both are bearing steel.

Manufacturer Ratings

Load-rating symbols are printed as each manufacturer writes them in its own catalogue, so the same quantity can carry a different symbol from brand to brand.

Brand	Dynamic Load Rating	Static Load Rating	Fatigue Load Limit
SKF 16030	C92.2 kN	C098 kN	Pu3.05 kN
NSK 16030	Cr92.5 kN	C0r91 kN	—
Schaeffler (FAG) 16030	Cr98 kN	C0r99 kN	Cur4.4 kN
NTN 16030	Cr107 kN	C0r101 kN	Cu5 kN
Timken 16030	Cr91.9 kN	C0r98.5 kN	—

Speed Ratings

Speed limits depend on sealing and lubrication, and definitions differ by manufacturer. Contact-sealed variants are normally greased for life and run slower. Always confirm the exact variant in the manufacturer's table.

Brand	Grease open / shielded	Oil open	Reference	Limiting
SKF 16030	—	—	6,000 r/min	3,800 r/min
NSK 16030	2,600 r/min	3,000 r/min	—	—
Schaeffler (FAG) 16030	—	—	3,100 r/min	4,050 r/min
NTN 16030	2,800 r/min	3,200 r/min	—	—
