The present invention provides a dynamic seal for enclosing a radial gap between coaxial, relatively rotatable inner and outer members. The dynamic seal includes an inner seal part, mountable to the inner member; an outer seal part, mountable to the outer member; and a counterface part radially suspended between the inner and outer seal parts and coaxial therewith. Each of the inner and outer seal parts provides a set of first and second sealing elements, which bear against oppositely oriented axial surfaces of the counterface part. The counterface part is thus axially retained in both directions by the inner seal part at a radially inner contact location, and is axially retained in both directions by the outer seal part at a radially outer contact location.

Dynamic seal

The invention provides a sealing assembly that includes an elastic seal lip having a movable part. The seal lip is configured to be attached to a first part of a machine and to be in sliding contact with a second part of the machine. It is proposed that at least one vibration sensor is fixed to the movable part of the seal lip.

Sealing assembly and method for monitoring dynamic properties of a sealing assembly

A sealing assembly including an elastic seal lip having a movable part is provided. The seal lip is configured to be attached to a first part of a machine and to be in contact with a second part of the machine. At least one acceleration sensor is fixed to the movable part of the seal lip, and that assembly further includes a data processing device for processing data obtained from the acceleration sensor. The data processing device is configured to determine the orientation of the acceleration sensor in relation to the direction of gravity.

Sealing assembly and method for monitoring a sealing assembly

A bearing assembly comprising a rolling element bearing having a first row of rolling elements arranged in a first bearing cavity between a first inner raceway and a first outer raceway of the bearing, and having a second row of rolling elements arranged in a second bearing cavity between a second inner raceway and a second outer raceway of the bearing. The assembly further comprises an annular grease cartridge arranged between the first and second rows of rolling elements. The annular grease cartridge is at least partly formed from a honeycomb structure having axially extending passageways filled with a grease lubricant, wherein at least some of passageways are open towards the first and second bearing cavities.

Bearing assembly with lubrication cartridge

A process for the manufacture of a lubricating grease composition, the process comprising steps of: (a) providing an essentially homogeneous liquid composition comprising a lubricating oil and a thickening polymer, and (b) flowing the liquid composition through a shear-mixing device to mix and cool the liquid composition to form a lubricating grease composition.

Polymer grease manufacturing process

A bearing assembly comprises a rolling element bearing having an inner ring, an outer ring and a set of rolling elements arranged in a bearing cavity between the inner and outer rings. A first grease is provided in the bearing cavity, which has a first thermal bleed rate at a specific reference temperature. The bearing assembly further comprises a grease cartridge, arranged at an axial side of the bearing cavity, whereby the cartridge has axially extending passageways that open into the bearing cavity, and whereby at least some of the passageways are filled with a second grease. The second grease has a second thermal bleed rate at the specific reference temperature which is lower than that of the first grease.

A cage for a ball bearing comprising a body of generally annular shape and clamps, the body comprising a heel of substantially annular shape and a substantially axial portion being connected to the heel and wherein recesses are arranged for the balls, the substantially axial portion supporting said clamps on the side axially opposite to the heel, the cage comprising an axial partition placed between the recesses and extending axially from the end of the heel opposite to the clamps toward the clamps while radially delimiting external free spaces and internal free spaces situated radially on either side of said partition.

Cage for ball bearing

A bearing arrangement comprises at least one bearing ring and at least one machine part with which the bearing ring is connected. The bearing arrangement is equipped with a device for detecting relative movement between at least one of the bearing rings and one of the machine parts. To facilitate the measurement of creep between one of the bearing rings and one of the machine parts, the device for detecting relative movement is located in or at the machine part and has a contact element which contacts the bearing ring, wherein a sensor element is arranged in or at the device to detect the relative movement between the device and the contact element.
