Why Vohann for STT Bearings
A clear route from bearing requirements to project supply.
Vohann is an authorized STT service provider. We help global engineering and purchasing teams define the requirement, review specifications, coordinate samples and quotations, and keep information aligned as projects move toward production.

More than
a catalogue hand-off.
Miniature bearing projects often begin with incomplete information. A team may have an existing part number, a shaft drawing, a target motor speed or a performance problem—but not yet a finished specification.
Vohann creates one customer-facing path for the technical, commercial and delivery questions that must be resolved before a bearing can move from initial discussion to validated supply.
One project,
distinct responsibilities
The relationship stays clear: STT is the product developer and manufacturer; Vohann is the authorized service and project coordination interface.
Requirements, communication and supply coordination.
Application discussion, specification review, samples, quotations, delivery requirements and ongoing project communication.
What Vohann
helps move forward
A disciplined project path reduces avoidable iteration and gives both engineering and purchasing teams a common set of facts.
Define the real requirement
Organise the application, installation envelope, speed, loads, accuracy, noise, environment and programme stage.
Review the product direction
Relate those conditions to STT product information, manufacturing capability and feasible specification paths.
Keep the project aligned
Coordinate samples, feedback, quotations, lead time, production introduction and repeat supply communication.
A practical
buyer journey
Start with what is available. Each step should make the next technical or commercial decision clearer.
| 1 · Initial input | Existing part number, drawing, dimensions, application description or current performance issue. |
|---|---|
| 2 · Requirement review | Clarify speed, loads, fit, noise, temperature, contamination, lubrication, duty cycle and validation target. |
| 3 · Specification path | Confirm which product information, dimensions, closure, material or special requirement needs review. |
| 4 · Sample and quotation | Align sample quantity, project timing, quotation basis, delivery country and estimated production demand. |
| 5 · Validation feedback | Keep test observations and requested changes connected to the product and project discussion. |
| 6 · Volume coordination | Maintain continuity across confirmed specification, commercial terms, lead time and repeat supply. |
Built for engineers
and purchasing teams
The same project needs different kinds of clarity depending on who is making the next decision.
Discuss operating conditions, geometry, performance targets, samples and validation feedback.
Confirm the product basis, quantity, quotation, lead time, delivery and supply continuity.
Connect bearing decisions with the mechanism, assembly process and production programme.
Use one structured enquiry path for product, commercial and delivery communication.
What to send
for a faster start
A complete drawing is useful, but not mandatory. The following information helps establish an actionable first review.
Current bearing reference, bore, outside diameter, width, shaft or housing drawing.
Speed, radial and axial load, temperature, duty cycle, noise and vibration requirements.
Dust, moisture, corrosion, cleanliness, lubrication preference and maintenance constraints.
Project stage, sample quantity, estimated annual volume, target timing and delivery country.
Bring the real requirement. Build the next step clearly.
Send a part number, dimensions, drawing or application conditions to begin.
