The codes 7408 and 7410 show two references in the 74 series. The numeric sequence distinguishes them within that series but does not describe the machine’s arrangement. The same catalog includes 7000 CD/P4A, with letters and a slash after the number, and 7205 BECBP, with a different final block.
Write each reference in full. Do not remove CD/P4A or BECBP to make a reference match a basic code found on another part. If a marking is only partly readable, a close-up photograph helps complete the request. Do not reconstruct one bearing’s code by copying the ending from the other member of the pair: record the actual markings on each part.
MR's catalog holds 1,126 SKF angular contact pages: 288 in series 70, 279 in 72, 172 in 73 and 132 in 719. The 7207 comes in 14 executions, each with its own page, such as 7207 BECBP, 7207 BEP and 7207 ACD/P4A.
