 ====== Technical specifications ======
+===== Spindle bearings ====
+Main bearings: currently NSK 7207CTRDULP4Y. Previously FAFNIR 207.
+Suitable NSK part numbers match ''^7207C(TR|TYN)D(U|B)(L|M)P4(|Y)$''
+If replacement is needed, the requirements are:
+  * angular contact bearings (7)
+  * 35x72x17mm (207)
+  * 15deg contact angle (C)
+  * any cage material suitable for spindles (TR, TYN, possibly some other options, see NSK designation guides)
+  * matched pair (D)
+  * universal or back-to-back arrangement (U, B)
+  * low or medium preload (L, M)
+  * ABEC7 or ISO P4 rating, those two are equivalent (P4)
+  * "special precision" is fine but not important (Y)
 ===== Spindle transmission =====
   * Minimum center distance - motor shaft to driven shaft: 244.5mm
