Please call us if your tolerance requirement is tighter that the figures quoted and we will discuss possible improvements and quality procedures with you.
Diameter
Tolerance
Up to 500
dia ± 2.0mm
500 to 1000
dia ± 2.5mm
1000 to 2000
dia ± 4.0mm
2000 to 3000
dia ± 6.0mm
3000 to 4000
dia ± 6.0mm
Over 4000 then tolerances +/- dia/1000
Max deviation = L/1000 or 6mm whichever is greater.
