Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Morgan Advanced Materials part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 3 series from our supply network are the closest match on published figures.
A small analogue power-and-signal slip ring with FASTON quick-connect terminals for fast wiring in dusty, high-cycle machinery. Optional IP65 sealing.

View Multi-channel Slip Ring →Slip rings using heat-resistant materials for extreme temperatures from -55°C to +250°C, such as hot rollers and heating plant.
View High & Low Temperature Slip Ring →Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
What a slip ring is
This group covers slip rings that do not fit a single standard format, including modular and split designs, contactless capacitive or optical data rings, temperature-rated units, quick-connect terminal designs, very high circuit counts and application-specific assemblies for wind turbines or packaging. All solve the same problem: transferring power, signals or data between stationary and rotating parts of a machine. What differs is the construction, which may be a split housing, a modular stack, a non-contact data path or a special material set.
When engineers choose a slip ring
Engineers look at these designs when a standard capsule, through-bore or pancake unit does not fit the job. Split rings suit retrofits onto existing shafts. Contactless data rings suit high data rates or long life without wear. Modular units allow circuit counts to change between machine variants. The trade-offs are cost, availability and, for custom designs, longer lead times and qualification. Match the construction to the real constraint, whether that is installation, data, temperature or circuit count.
How to specify the Morgan Advanced Materials Wind turbine carbon brushes (incl. National S22)
Send these with your enquiry and an engineer can confirm the right Wind turbine carbon brushes (incl. National S22) variant or an equivalent:
- What makes the application non-standard: installation, data, temperature, circuit count or format
- Circuits, current and voltage (A, V)
- Data protocols and rates
- Speed (rpm) and expected life (revolutions)
- Bore, envelope and mounting (mm)
- Temperature range (°C) and IP code
- Terminations, such as flying leads, connectors or quick-connect tabs
Common mistakes to avoid
- Choosing a special design when a standard type with minor changes would do
- Not stating the actual constraint, so the supplier offers the wrong format
- Assuming contactless data channels also carry power
- Underestimating lead time for custom or modular builds
Morgan Advanced Materials Wind turbine carbon brushes (incl. National S22): frequently asked questions
What is the Morgan Advanced Materials Wind turbine carbon brushes (incl. National S22)?
Phase, earth/grounding, lightning protection and pitch control brushes in around 20 grades for bronze, steel and high-load rings, including the National S22 silver grade, with cross-references for most major turbine platforms. It is made by Morgan Advanced Materials plc; Specify Motion can help source it or propose an equivalent.
Who makes the Morgan Advanced Materials Wind turbine carbon brushes (incl. National S22)?
The Morgan Advanced Materials Wind turbine carbon brushes (incl. National S22) is made by Morgan Advanced Materials (Morgan Advanced Materials plc) and is listed here for engineers comparing options. Specify Motion is not affiliated with Morgan Advanced Materials plc; brand names are used only to identify the product.
Is there an alternative to the Morgan Advanced Materials Wind turbine carbon brushes (incl. National S22)?
Yes. On published figures, HR Series Faston Type Slip Ring and Multi-channel Slip Ring are the closest match from our supply network. An engineer confirms the fit against your application before recommending anything.
What is a split slip ring?
A split slip ring has a rotor and housing made in two halves, so it can be fitted around an existing shaft without removing the shaft or its bearings. It suits retrofits and large machines where disassembly would be costly. Expect tighter installation tolerances and possibly a lower speed rating than a one-piece unit.
What is a contactless slip ring?
A contactless slip ring transfers data, and sometimes power, across rotation without sliding contacts, using capacitive, inductive or optical coupling. There is no wear on the data path, so life is long and very high data rates are possible. Contactless power is usually limited, so many designs combine a contactless data channel with conventional power rings.
