chrisash Report post Posted August 2, 2018 just looking up PFAFF needles size 134 Check online and it states the needles are the same as PFAFF 134 797 135x5 135x7 DPX5 135x Are these really the same common needle and if so why so many different descriptions Quote Share this post Link to post Share on other sites
DrmCa Report post Posted August 2, 2018 dunno about 797, never came across those, but the rest is the same needle. This is the standard needle for Pfaff walking foot machines. Why? Hell knows! Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted August 2, 2018 Different manufacturers used to assign their own system codes to needles when they produced those lines, many of which were based on early Adler, Pfaff and Singer needles. European needle makers called their needles by different codes than American/Canadian makers. There is a gap between SAE/ISO and Metric measurements, so needles made to different measurement systems get different names, even though the geometry may end up the same.

brmax Report post Posted August 3, 2018 No there not all the same, and its truthfully surprising how these have been made different. In some ways a needle may be ground in machining to have a difference in its point, thread eyelet, the scarf area and upwards. Possibly marketing and manufacturing to peform better for a specfic task and in a machine of some brand or other. I think we see some of this in different point angles and for sure taller thread eyelets or holes. Good day Floyd Quote Share this post Link to post Share on other sites
Constabulary Report post Posted August 3, 2018 (edited) The needles are the same - you may find minor differences among different manufacturers but they all have the same length from top of shank to top of needles eye (as said before - with minor differences) - meaning they are interchangeable. Shank diameter is ~2mmm, length from top of shank to top of needle eye is ~33,9mm Other names for this needle is: DPx134, SY 1995 or even CANU 20:05 1 EDIT: Edited August 3, 2018 by Constabulary Quote Share this post Link to post Share on other sites
chrisash Report post Posted August 3, 2018 Thanks guys most enlightening, I guess the marketing folk thought that having a different name would make customers only go to them to buy needles rather than a generic needle, Further question does the needle thickness get thinner (not shank) if the size goes down from say 130 to 90 Quote Share this post Link to post Share on other sites
