Notes on this data
No current, voltage, speed, IP or temperature figures published on the pages read.
Specify Motion is not affiliated with BGB (family-owned; legal entity name not stated on its website). BGB and Wind turbine slip rings are used only to identify the product. Comparisons use published figures; always confirm against the current datasheet.
BGB Wind turbine slip rings replacement and alternative options
Use these supply-network options as a starting point for an engineering check. We can also help source the original BGB part. Published series figures do not establish an exact-model or drop-in replacement: confirm ratings, fit, interfaces and approvals for your application.
Slip rings using heat-resistant materials for extreme temperatures from -55°C to +250°C, such as hot rollers and heating plant.
A small analogue power-and-signal slip ring with FASTON quick-connect terminals for fast wiring in dusty, high-cycle machinery. Optional IP65 sealing.
High-circuit-count slip rings that carry hundreds of mixed power, digital, analogue, fibre and RF channels in one unit.
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.
Typical applications
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 BGB Wind turbine slip rings
Send these with your enquiry and an engineer can confirm the right Wind turbine slip rings 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
BGB Wind turbine slip rings: frequently asked questions
Can you help replace BGB Wind turbine slip rings or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including supply-network options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the BGB Wind turbine slip rings?
Pitch-control, hub and power slip rings for wind turbines, supplied new and as aftermarket replacements for major turbine platforms, with through-bore, pancake, high-current, capsule and fibre optic variants. It is made by BGB (family-owned; legal entity name not stated on its website); Specify Motion can help source it or propose an equivalent.
Who makes the BGB Wind turbine slip rings?
The BGB Wind turbine slip rings is made by BGB (BGB (family-owned; legal entity name not stated on its website)) and is listed here for engineers comparing options. Specify Motion is not affiliated with BGB (family-owned; legal entity name not stated on its website); brand names are used only to identify the product.
Is there an alternative to the BGB Wind turbine slip rings?
We can assess suitable replacement options. On published figures, Motion Control Products High & Low Temperature Slip Ring and Motion Control Products HR Series Faston Type Slip Ring are options to assess 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.
