TBI-VAC / Environment + load

Vacuum & High-Current Slip Rings

Define a vacuum-compatible, high-current or sealed rotary interface for semiconductor equipment, wind pitch systems and crane cable reels.

Typical design brief: Vacuum chucks, coating chambers, pitch drives and marine winches.

Exact imperial conversions: 0.5″ = 12.7 mm · 1″ = 25.4 mm · 1.5″ = 38.1 mm · 2″ = 50.8 mm · 3″ = 76.2 mm · 4″ = 101.6 mm. Metric 50 / 70 / 100 mm bores remain separate choices.

APPLICATION REVIEW

What determines a workable TBI-VAC?

High vacuum, IP68 immersion, extreme temperature and 500 A are separate design branches. They are not combined standard ratings.

Vacuum pressure, outgassing, materials and bakeout
Continuous / peak current, voltage and cooling
For IP68: depth, duration, medium and rotation duty

Replacing an existing assembly? →

Concept mounting: rotor on independently supported shaft, stator tab restrained with compliance

Give the stator a flexible stop.

For a shaft-mounted design, secure the rotor as its drawing specifies and restrain the stator with an anti-rotation tab that accommodates misalignment. Avoid rigidly locking both sides. Mounting is model-specific; flange and capsule designs may differ.

Assembly options

Illustrative accessory allowances, subject to compatibility and written quotation. Two options are preselected; clear either if unnecessary. Connector quantity, circuit count, wire gauge, custom harness work, sealing, shipping and any NRE are priced for the agreed configuration.

Connector preferenceExtended lead length

Connector and extended-length selections apply only when their corresponding assembly option is checked. Wire material, sealing scope and connector suitability require approval.

No payment is collected. No stock, dispatch date or performance is reserved by this request.

TBI-VAC engineering questions

Does IP68 mean vacuum compatible?

No. Immersion sealing and vacuum material/outgassing requirements are different. Specify and validate the operating environment independently.

Is 500 A available at every bore and speed?

No. Current, heat removal, contact geometry and duty determine feasibility. Provide a complete load profile for engineering review.
