Sizes of precision seamless tubes
Standard precision tubes are practically used in all areas of the machine production. Seamless steel tubes can be supplied as cut tubes and bent tubes. Cut tubes are designed especially for manufacturers of automotive components.
Dimensions of precision tubes for bearing rings
– outside diameter x wall thickness (OD x WT):- 22.0 x 3.0 – 70.0 x 8.0 mm
- for bearings *
Dimensions and weights of seamless tubes according to standard A/SA-999; A/SA-333 (A/SA-335) minimal wall thickness (A/SA-1016; A/SA-213; upon agreement average WT)
