RINGSPANN shaft-hub connections

Select a RINGSPANN shaft-hub connection by the surfaces it must join in the drive. This line includes shrink discs and tapered locking elements, making position relative to shaft and hub fundamental. These are not simply different names for one part. For replacement, reconstruct the original mounting, distinguish which elements rotate together, where tightening occurs and which parts remain in the machine.

Identifying the designation

4200-014301-000000 is listed as a shrink disc, while 4201-020001-000000 and 4204-070601-TC0000 are tapered locking elements. All have hyphen-separated blocks, but a shared structure does not establish identical function or dimensions. Copy every zero and retain TC where present. Check middle numbers against the record and mounting dimensions rather than directly reading them as a diameter or transmissible torque.

Application and machine position

At a conveyor drum, roller drive or wheel attachment, review these parts with shaft and hub. Document whether the element surrounds the hub externally or sits between the surfaces being joined. That position guides system identification. Screw access, contact length and surface condition also matter. Include any shaft or bore modification because it changes the geometry against which the reference is compared.

Information for a quote

Send MR Accesorios Industriales the full code, relevant inside and outside diameters, length and photographs of the opened assembly. State application, quantity and position in a sketch. Add known working torque as a drive requirement for review, separately from measured dimensions.

Are a shrink disc and tapered locking element equivalent?

Not because they share this category. Identify position and the surfaces each connects before comparing.

Can zeros be omitted from an inquiry?

No. Complete blocks belong to the reference and distinguish records that could look identical when shortened.

Is shaft measurement sufficient?

Hub geometry, useful length and mounting position are also required. The connection is defined by the relationship between both components.

Main series

RINGSPANN Conical Shaft-Hub Connections

Conical shaft-hub connections are fastening elements that transmit torque by radial tightening between a shaft and a hub, without the need for a key or additional machining. They are mounted in the annular space between both parts and, when actuated, generate uniform pressure that locks the connection. MR Accesorios Industriales offers the RINGSPANN line in Buenos Aires, Argentina, with technical advice to select the size according to each application's part number.

RINGSPANN Shaft-Hub Locking Assemblies

RINGSPANN shaft-hub locking assemblies are tapered clamping elements that allow mounting pulleys, gears, cams or any hub onto a shaft without a keyway. When the screws are tightened, the inner cone expands and generates uniform pressure that locks the assembly by friction. This simplifies the design, eliminates shaft weakening from a keyway and makes fine adjustment of the angular position easier. MR Accesorios Industriales supplies this line in Buenos Aires, Argentina, with technical advice to select the right model.

RINGSPANN Shrink Discs

A shrink disc is a shaft-hub connection component that transmits torque through friction, without a keyway or backlash. It is mounted on the hub and, when its screws are tightened, compresses the hub against the shaft, creating a rigid, detachable connection. It is used in power transmission, gearboxes, machine tools and equipment where high precision and reliability are required. MR Accesorios Industriales sells the RINGSPANN line in Buenos Aires, Argentina.
