Today’s manufacturing sector is concerned with the amount of downtime spent on scheduled and unscheduled maintenance. The dollars lost to unscheduled maintenance by itself can be quite substantial. All industrial facilities use some type of flexible coupling for pumps, compressors, conveyors, and other machinery.
Fact is, flexible couplings all require some type of maintenance. Gear and grid type flexible couplings require lubrication. To lubricate these types of couplings, the lube plugs must first removed and then the coupling is filled with grease. Various elastomeric type flexible couplings require periodic change of the elastomeric element. The difficultly level for different types of elastomeric couplings can vary widely. Some, like the standard jaw product, require that one of the hubs be moved back on the shaft to allow for the element to be changed-out. Machinery may have to be moved to allow for this hub movement, which can be very time consuming.
Other elastomeric designs have many fasteners and parts to be disassembled for element change-out. In either case, the time that it takes to change this element is critical for maintenance personnel. This is where the advantages of the Lovejoy Jaw In Shear 6 Pin design provide a solution to plant downtime. There are no tools necessary, no hubs to move, no messy lubrication to deal with and best of all – elements can be changed in minutes.

DELTEX - XS Torsionally flexible spider replacement couplings, made of steel or stainless steel
This patented elastic shaft coupling is a new Innovation. After removing
the safety cover the spider can exchanged easily without moving the
driving or driven side (for example motor or pump). After removing the
cover the separable spider can be exchanged without any problem.

- Double cardanic curved-tooth gear coupling
- Maintenace-free due to the material combination of steel and nylon
- For all applications in the range of general engineering and hydraulics
- Axial plug-in, easy assembly
- Compensating for axial, radial and angular shaft misalignment
- Finish bore according to ISO fit, kayway according to DIN 6885 sheet 1,
JS9 and P9
- Surface protected steel parts (zinc-coated and passivated, Cr6+free)
Caracteristics of the DELWEX - sleeves (material polyamide):
- High mechanical consistency and stiffness
- Favourable slide-friction behaviour
- High thermal stability to +100°C
- Good viscosity even in case of low temperatures
- Very good electrical insulating property
- Good resistance to chemicals
Behaviour of wear and friction of the DELWEX - sleeves:
The high thermal stability and resistance to lubricants, fuels,
dissolvents, hydraulic fluids, etc. make polyamide an ideal material
for components stressed by sliding, particularly for the coupling
production. While any metallic materials tend to "corrode" in case of
dry running, slide combinations with steel and polyamide are operative
without any lubrication and maintenance.

Rotary Systems designs and manufactures a line of standard and custom over-the-shaft rotary unions.
The rotary union shown is constructed from carbon steel and utilizes a precision ground shaft, radial ball bearings and Teflon seals. This is a two passage rotary union with .25" NPT passages with a four inch bore through the shaft. This union was designed specifically for a high pressure hydraulic indexing application.
Our standard over-the-shaft line of rotary unions can be viewed on our website by clicking on the 011 series. Our standard unions are offered in two and four passages with a .5", 1.5” or 2.0” bore through the shaft. The bore through the shaft is independent from the union. Some customers will pass a shaft or electrical wires through this bore.
If you have a custom rotary union application, please contact our Technical Sales department at 1-800-959-0146.
