KTR Split Coupling: Advantages and Applications
As a coupling manufacturer with over 60 years of innovative experience, KTR has been seeking to improve existing designs. For decades, KTR has incorporated split wheel hub design (such as machined ROTEX A-H steel) as part of our products. However, as the industry's demand for new efficiency and cost savings continues to grow, KTR has extended the concept of split couplings to other key product lines.
The split type hub coupling design features a hub that divides the hub into two halves. This type of design makes it easy to assemble the upper and lower shafts, simplifying the maintenance process and reducing downtime. The basic feature of any split wheel hub design is two wheel hub halves that are separated from each other by a horizontal split (parallel to the axis). This effectively causes the hub half to fall off the shaft without the need to move driving or driven components such as pumps or motors.
Assembly is achieved through at least two screws that connect the hub halves together, and may have a clamping effect (depending on the specific design), which is advantageous for certain applications.
Some split design wheels (such as ROTEX S-H) can even be provided in boring situations, providing greater flexibility for maintenance procedures. It is worth mentioning that due to the reduction of hub materials available for drilling, the position of fastening screws in the hub is reduced by the number of large allowable holes given the hub size.

Maintenance advantages of split type couplings
Although bifurcated couplings are not suitable for every application, they do have multiple advantages, especially in terms of maintenance.

Due to the design of the wheel hub in half, it can be easily removed to repair the coupling. This means that heavier components can be retained in their original positions, simplifying the problem of re alignment and eliminating the need for heavy lifting equipment, which is typically the expensive and time-consuming part of repairing large couplings. On the contrary, for smaller sizes, a detachable design typically allows for disassembly in applications with limited space or safety covers.

It should also be noted that existing couplings must still be removed before being replaced with a split wheel hub design, so the benefits of a split design are usually not always obtained from the beginning. This leads to another consideration, that is, the benefits of designing separate wheel hub couplings are usually long-term. Compared to standard equivalent products, it is usually necessary to produce higher prices related to split type wheels and consider the maintenance costs saved during the service life of the coupling.


Application Areas
At KTR, split wheel design can be used on the following product series: ROTEXSH ® And ROTESAH ® (Jaw type coupling), BoWexGT ® (Nylon sleeve gear type), RIGIFLE-N AH (disc/gasket type), and REVOLEX KX-D (pin and bushing type). Our extensive split design can provide customers with solutions tailored to their specific applications.
