Page 13: General Notes
Flender accepts no responsibility for damage or disruption caused by disregard of these instructions. The "FLENDER coupling" described in these instructions has been developed for stationary use in general engineering applications. The coupling is designed only for the application described in section 1, "Technical data". Other operating conditions must be contractually agreed. -
Page 14: Safety Instructions
If the coupling is intended for installation in plant or equipment, the manufacturer of such plant or equipment must ensure that the contents of the present operating instructions are incorporated in his own instructions. • All spare parts must be obtained from Flender. ZAPEX 3502 en Operating instructions 10/2017... -
Page 15: Transport And Storage
The coupling is delivered in a preserved condition and can be stored in a covered, dry place for up to 6 months. If the unit is to be stored for a longer period, it should be treated with a longterm preservative agent (Flender must be consulted). 4.3.2 Storage of the DUO sealing rings 4.3.2.1 General... -
Page 16: Technical Description
Technical description Observe the instructions in section 3, "Safety instructions"! If a dimensioned drawing has been made out for the coupling, the data in this drawing must be given priority. General description ZAPEX type ZWBT, ZWBG, ZWB, ZWH and ZWHD couplings are provided for connecting two shafts. The shaft ends to be connected must be supported immediately upstream of and downstream of the coupling. -
Page 17: Types Zwh And Zwhd
5.1.2 Types ZWH and ZWHD ZWHD Torque is transmitted from the shaft over parallel key, shrink fit or a comparable connection to the coupling part (1), then over the tooth system to the coupling sleeve (5) and from here over the tooth system to the coupling part (2) and then again via the parallel key, shrink fit or a comparable connection to the shaft. -
Page 18: Fitting
Flender should be consulted. If other shaft-hub connections (e.g. spline bore hub profile, tapered or stepped bores, parallel-key connections with tightening) are to be used instead of the provided parallel-key connection, Flender should be consulted. Failure to observe these instructions may result in breakage of the coupling. -
Page 19: 6.1.1.1 Parallel Keyway

6.1.3 Set screws in case of parallel-key connection Hexagon socket set screws with cup points to DIN 916 must be used for set screws. The following guidelines must be observed!

Check space requirement for inserting the cheese-head screws (11), and, if necessary, insert the screws (11) in the cover (10 and/or 21).

Page 24: Fitting Coupling Parts (1/2) In Case Of A Cylindrical And Tapered Interference Fit Set Up For Removal By Oilhydraulic Shrinking Off
Fitting coupling parts (1/2) in case of a cylindrical and tapered interference fit set up for removal by oilhydraulic shrinking off The information specified on the dimensioned drawing must be observed. Before fitting, the screw plugs (22) must be unscrewed from the coupling parts (1/2) and all parts and the shaft ends carefully cleaned and dried. -
Page 25: Fitting The Coupling
The coupling parts (1/2) should be pushed smartly onto the shaft up to the position specified in the orderspecific dimensioned drawing. The coupling parts (1/2) must be held in position on the shaft with the aid of a suitable retaining device, until they cool down and seat firmly. -
Page 26: Alignment
Alignment The types ZWB, ZWH and ZWHD compensate for positional errors up to 1° of the shaft ends to be connected. Due to axialbacklash limitation types ZWBT and ZWBG compensate only for a positional error of up to 0.3°. When aligning, the radial and angular misalignment of the shaft ends must be kept as small as possible, because, other conditions being equal, this increases the service life of the coupling. -
Page 27: Possible Misalignments
ZWH, ZWHD Dial gauge Ruler Ruler Caliper gauge With small distances "S", a ruler and caliper gauge can be used instead of a micrometer and tape measure. The max. permissible misalignments depend upon the duty factor, axialbacklash limitation and coupling speed. If the speed changes, a check must imperatively be carried out. -

For normal operating conditions we recommend oil. This has the advantage of easy oil changing and good surface wetting. The lubricants are suitable for operating temperatures of between 10 °C and + 80 °C. If temperatures deviate from these, consult Flender.

Page 34: Faults, Causes And Remedy
Flender will not be bound by the terms of the guarantee or otherwise be responsible in cases of improper use of the coupling, modifications carried out without the agreement of Flender, or use of spare parts not supplied by Flender. -
Page 35: Maintenance And Repair
Maintenance and repair Observe the instructions in section 3, "Safety instructions"! If a dimensioned drawing has been made out for the coupling, the data in this drawing must be given priority. 10.1 General The coupling must be checked for leaks and heating, and any change in the noise level, at general maintenance intervals or at least every three months. -
Page 36: Demounting The Coupling Parts (1/2) In Case Of Shaft-Hub Connection With Parallel Key
10.4 Demounting the coupling parts (1/2) in case of shaft-hub connection with parallel key Unscrew the screw plugs (6) and drain off the oil or grease into a suitable vessel, as shown in the diagram above (to simplify matters, in case of grease, add lightbodied oil to the used grease and mix). All the oil or grease must be completely collected and disposed of in accordance with the regulations applying. - Page 37 (material of screws and spindles min. 10.9, material of nuts identical to that of the screws). • 1 hydraulic cylinder ("Lukas") with oil pump. Note displacement and pressure of the hydraulic cylinder (”Lukas”) (for axial force, consult Flender and/or refer to dimensioned drawing). Observe manufacturer's instructions for using forcingoff/detaching device and pumps.
