– Solid and split covers are designed to accommodate higher speeds and increased torque.
– Inherently balanced from precision machining for high-speed applications.
– Design dampens torsional vibration and shock to help extend life of the coupling and surrounding components.
The SXCST Type Close Coupled Split Spacer Coupling is manufactured by Lovejoy, and has two flex planes to accommodate the parallel misalignment by the angular misalignment in each disc pack. The unit has a split spacer design that allows easy maintenance and replacement of disc pack without moving the equipment.
Fits standard SAE UJ (Universal Joint) companion flanges. Release torque is adjustable by Wedgepin ratings. The maximum release torque is based on maximum Wedgepin capacity and not UJ shaft capacity- Check your UJ shaft manufacturers max load rating. Spigot diameters may change on higher rated UJ shafts. When selecting high overloads always limit the release torque to 90% of UJ shaft
The GPL series from AB Transmission are hub-hub couplings designed with integrated rubber elements and a spacer. These devices are suitable for use in different types of application, which require rapid and easy maintenance operations on the coupled machines. In addition, these tools allows replacement of the rubber elements, and hubs dismounting due to the available spacer.
Hub-hub couplings with rubber elements with spacer, for applications where maintenance operations on the coupled machines are required without moving them. They have a hub and a bush already machined with bore and keyway. Especially suitable for electric pumps.
Made in steel fully turned with standard treatment of phosphating. Disc pack in stainless steel. High torsional rigidity. Maintenance and wear free. Version with double disc pack: GTR/D. High torque possible.

Choosing an Alignment Measurement Setup
Having taken care of the preliminaries, we are now ready to choose an alignment setup, or arrangement of measuring instruments. Many such setups are possible, generally falling into three broad categories: face-and-rim, reverse-indicator, and face-face-distance. The following sketches show several of the more common setups, numbered arbitrarily for ease of future reference. Note that if measurements are taken with calipers or ID micrometers, it may be necessary to reverse the sign from that which would apply if dial indicators are used.
Figures 5-3 through 5-8 show several common arrangements of indicators, jigs, etc. Other arrangements are also possible. For example, Figures 5-3 and 5-4 can be done with jigs, either with or without breaking the coupling. They can also sometimes be done when no spacer is present, by using right-angle indicator extension tips. Figures 5-6 and 5-7 can be set up with both extension arms and indicators on the same side, rather than 180° opposite as shown. In such cases, however, a sign reversal will occur in the calculations. Also, we can indicate on back of face, as for connected metal disccouplings. Again, a sign reversal will occur.
In choosing the setup to use, personal preference and custom will naturally influence the decision, but here are some basic guidelines to follow.
This is the setup we prefer for most alignment work. As illustrated in Figure 5-9
Accuracy is not affected by axial movement of shafts in sleeve bearings.
Both shafts turn together, either coupled or with match marks, so coupling eccentricity and surface irregularities do not reduce accuracy of alignment readings.
Face alignment, if desired, can be derived quite easily without direct measurement.
Rim measurements are easy to calibrate for bracket sag. Face sag, by contrast, is considerably more complex to measure.
With suitable clamp-on jigs, the reverse-indicator method can be used quite easily for measuring without disconnecting the coupling or removing its spacer. This saves time, and for gear couplings, reduces the chance for lubricant contamination.
