A system includes a wind turbine having a fixed part and a rotational part and a brake having a brake disk mounted to the rotational part for rotation with the rotational part. At least one brake block is fixed relative to the fixed part and has a friction surface facing the brake disk. The brake block is shiftable between a first position with the friction surface spaced from the brake disk and a second position with the friction surface in contact with and pressed against the brake disk, and the friction surface and/or the brake disk are configured such that pressing the at least one brake block against the brake disk creates a micro-interference fit between the at least one brake block and the brake disk.

A rolling-element bearing unit for use in a motor vehicle wheel or in a motorbike rocker arm includes outer and inner raceway elements and a set of rolling elements between the inner and outer raceway elements such that the inner and outer raceway elements are pivotable or rotatable relative to each other and also a lubricant reservoir body in the bearing interior for storing and dispensing a lubricant, the body including bridge elements extending between adjacent pairs of the rolling elements and a side ring connecting the bridge elements.

A guide roller configured to guide a wire to or from a work roller in a wire rolling line includes a rolling-element bearing having a rotatable outer ring, a fixed inner ring, and rolling elements between the outer ring and the inner ring. The outer ring has a profile configured to guide the wire on a radially outer surface thereof. The guide roller is configured as a double row preloaded rolling-element bearing and is installable as a finished component on a fixed shaft of the wire rolling line without adjusting the preload.

A rolling-element bearing includes a first bearing ring, a second bearing ring, and a seal unit formed in a multiple-piece manner, the seal unit including an at least part-ring shaped main element which is freely rotatable with respect to the first bearing ring and the second bearing ring and at least one seal lip. In addition, the main element and the seal lip are exchangeably connectable to each other.

A seal unit for a rolling-element bearing having an inner bearing ring and an outer bearing ring. The seal unit includes an at least part-ring shaped element having a seal lip, the at least part-ring shaped element is configured for attachment to the inner bearing ring, and the outer bearing ring is tiltable through a limited angle with respect to the inner bearing ring. Also a rolling-element bearing having such a seal unit.

A bearing device for a solar power plant unit includes at least one support element, at least one first roller and at least one second roller. At least one first roller bearing unit is movably supported on the support element and rotatably supports the at least one first roller and the one second roller. At least one first spherical plain bearing having an outer ring is attached to the at least one first roller. A solar power plant includes at least one mirror movably supported by at least one such bearing device.

A part-bearing-ring of a rolling-element bearing includes first and second assembly bores on its end surface, and the second assembly bore has a larger diameter than the first assembly bore so that it can accommodate a securing sleeve. The second assembly bore may include an internal thread for attaching the securing sleeve. Also a bearing ring formed of two part-bearing-rings and a securing sleeve and a method of installing a bearing ring.

Part-bearing-ring, securing sleeve, rolling-element bearing, and mounting method

A rolling-element bearing includes a first bearing ring () and a second bearing ring () opposing the first bearing () in a radial direction (). A sealing element () of the rolling-element bearing includes a radially-encircling seal support () extending in the radial direction () by a predetermined distance towards the second bearing ring (). The seal support () is interference-fit and removably attached to an axial end side () of the first bearing ring (). A sealing lip () is attached to the seal support () and extends from an end of the seal support () opposite the first bearing ring () in the radial direction () up to a mating surface (), which is part of the second bearing ring ().
