1) In the technically justified cases, after consultation with the orderer it is allowed to make chain of diameter d with tolerance without a positive deviation.
2) type K - means chain calibrated ( no marking K - means chain not calibrated)
3) For not calibrated chains dimensions  tb1 and  b2 shall be taken as indicative values and  after consultation with the customer are subject to change.

Chain type N minimum breaking stress Rz  min. 240 MPa ( grade 2 )
Chain type U minimum breaking stress Rz  min. 300 MPa ( grade 3 )

We have in our production program chains of dimensions according to PN-75/M84540 in strength grades 5, 6, and 8. These chains are made based on WT ( Manufacturer's specification )
