SIPEX and BIPEX-S Backlash-free Couplings

Article number code

The article number consists of a combination of digits and letters and is divided into three blocks linked by hyphens for better clarity. The coupling series, the type and the size are encoded in blocks 1 and 2. Block 3 contains information applying only to the coupling specified in blocks 1 and 2. The three blocks of the article number are supplemented by information on the bore of the coupling hub parts and information on "Special Types".

The bore details with the code letter L always refer to the bore diameter D1 of the hub part shown on the left on the dimension drawing. The order code beginning with M always refers to the bore diameter D2 of the hub part shown on the right on the dimension drawing.

The order code without the letter "-Z" refers to tolerance H7 without keyway. An exception to this rule is type BNN of series -BIPEX-S to which tolerance H7 with keyway applies.

To order other types with keyway, the letter "-Z" must be appended to the article number.
L40 / M40 = Keyway according to DIN 6885, keyway width JS9
L41 / M41 = Keyway according to DIN 6885, keyway width P9

Bore specifications

Additional identification code with order codes for bore specifications (no letter "-Z" required)

Identification codes with order codes have been specified for the bore specifications.

A bore is ordered by specifying the digit 9 in the 11th and 12th places of the article number and by adding the appropriate order codes for ∅D1 and ∅D2 from the table below.

Unless a different bore tolerance is specified, H7 is selected for all metric bore diameters.

To order a bore diameter other than the values stated in the table, the digit 9 must be specified in the 11th and/or 12th place of the article number; in addition, the letter "-Z" must be added to the article number as well as the order code L9Y with plain text for the left-hand hub and/or order code M9Y with plain text for the right-hand hub.

Additional identification code with order code for shaft distances (no letter "Z" required.

Order specification with order code Q0Y has been specified for the shaft distance.

Shaft distance is ordered by specifying the letter Z in the 15th place of the article number, adding order code Q0Y and providing additional information in plain text for dimension S (shaft distance).

Ordering example:

SIPEX SHH-W coupling, size 60
Shaft distance S = 1000 mm
Total length LG = 1044 mm
Bore ∅D1 24 H7
Bore ∅D2 28 H7
