A sealing assembly for bearings, in particular for use in agriculture, comprising a primary sealing barrier and a secondary sealing barrier, which are arranged in series along a potential path (P) of ingress of contaminants into the bearing, and have, respectively, a first seal and a second seal with a plurality of contact lips. The contact lips of the first and second seal with a plurality of contact lips may be static lips that do not rotate about an axis (A) of rotation of the bearing.

Sealing assembly for bearings, in particular for use in agriculture

Sealing device including a first annular element coupled to a first fixed mechanical member, and a second annular element coupled to a second rotating mechanical member, for protecting an annular compartment delimited between the members; the first element being provided with at least one annular sealing lip configured to interact with the second element, which has a radial edge of a flange portion arranged at an edge of a sleeve portion of the first element, thus forming with the latter a radial gap configured as a labyrinth seal; wherein the radial gap of the flange portion of the second annular element carries a plurality of depressions arranged in a crown, spaced adjacently to one another at the radial gap and configured to generate, as a result of the rotation of the second element, a dynamic effect (F) for the purpose of repelling any contaminants impelled towards the radial gap.

Sealing device with dynamic action, particularly for rolling bearings

A dynamic seal having a contact surface including a fabric is provided. A fatty acid ester is incorporated into the fabric.

Dynamic seal

A dynamic seal having a contact surface providing poly(norbornene) or a derivative thereof.

The invention provides a building block for a mechanical construction. The invention further provides a bearing and a method of producing the building block. The building block provides a first printed material printed via an additive manufacturing process on or at least partially embedded in a second material. The first printed material is printed in a pattern configured and constructed for cooperating with a sensor for providing position information of the building block relative to the sensor. The sensor may be a magnetic sensor or an optical sensor. The first printed material may include magnetic particles. The method of producing the building block may include a step of adding the first printed material to the second material via the additive manufacturing process under the influence of a predefined magnetic field.

Building block for a mechanical construction

An elastomeric seal, the seal () having an elastomeric part () with a contact surface () for contacting, in use, a movable surface (), the contact surface having a distribution of dimples thereon, the dimples having a depth of at least 9 &#x3bc;m, an aspect ratio of at least 0.2 and an area density of from 0.05 to 0.5.

Low-friction seal

A rolling bearing comprising an outer ring, an inner ring, at least one row of rolling elements that are disposed radially between the rings, at least one seal forming a first sealing component that is fixed to one of the rings and engages with the other ring, and at least one flange forming a second sealing component that is fixed to the other ring and is offset axially with respect to the seal on the outer side of the bearing. At least one of the first and second sealing components comprises at least two annular ribs, the other sealing component being mounted axially in contact therewith. At least one closed annular space is delimited by the ribs and by the other sealing component. At least one lubricant is disposed inside the space.

Rolling bearing comprising a sealing flange

A sealing device is to be fitted at a side of a bearing unit in order to seal a gap () between a stationary race () and a rotatable race () of the bearing unit. The device includes a relatively rigid reinforcing insert () of disc-annular shape, and a gasket () of relatively soft rubber or elastomeric material, over-moulded or vulcanized onto the insert (). The gasket forms two opposite peripheral sealing portions () intended to perform a static sealing action against the rotatable race () and a dynamic sealing action on the stationary race (), respectively. The insert () includes magnetized or magnetizable material for forming, at predetermined angular zones or fields, a sequence of alternate and/or spaced north/south poles, in order to act as an encoder.
