Tapered bearings are provided for use on each end of each link arm on an agricultural seed row planter mounted on a toolbar. The bearing is a low friction material and greaseless. The tapered design of the bearings allows the bearings to be adjusted as wear occurs, by tightening the link arm mounting nut which extends through the tapered bearing. The tapered bearing has an increased life and reduced maintenance, as compared to prior art roller bearings.

A bearing assembly for supporting a rotor in a fixed housing includes multiple slide bearing segments, each having a slide bearing body supported against a sliding surface. In the region of each slide bearing segment, the bearing clearance between the respective slide bearing body and the sliding surface is adjustable by an adjustment screw, each adjustment screw having an outer thread via which the screw can be screwed into a recess having an inner thread, each adjustment screw having a groove delimited on both sides by adjustment screw sections. A clamping screw extends through the adjustment screw sections and also through the groove, the adjustment screw sections can be clamped by the clamping screw, whereby each adjustment screw can be secured in the respective recess.

A sliding element works with a guide system having two guide parts that can be moved relative to one another. The sliding element can be fixed to one of the guide parts by an attachment face (3) and includes, on a face opposite the attachment face (3), a sliding surface (6) so as to be slidingly supported on the other guide part. The sliding element includes a first part (I) and a second part (2) which is mounted so as to be rotatable relative thereto, which parts include a contact surface (3) for mutual support. The contact surface (7) is axially inclined in a rotational direction of the second part (2) counter to the first part (I), and the two parts (I, 2) can be locked to one another in various angular positions and the locking can be released.

Proposed is a novel coupling mechanism capable of applying a preload to a ball portion and a socket portion which constitute a coupling mechanism of a titling pad bearing, without using a spring element.

A very compact play-free bearing unit includes a bearing that runs without play while having a reasonably large play when assembling and during disassembly of the bearing unit from its axle. The bearing unit uses three bearings, one of which is mobile, and thanks to a preloading mechanism the play is removed when loaded. Thanks to an amplification lever, the preloading unit is able to function either with a pneumatic actuator or with a hydraulic actuator.

Bearing assemblies and methods of using bearings are provided in the present disclosure. In one embodiment, a bearing ring is provided having a plurality of carrier components removably coupled therewith. Each carrier component may carry one or more bearing elements. Upon wearing of the bearing elements beyond a desired amount, the carrier components may be removed from the bearing ring and installed in a different bearing ring to place the mearing elements at their original bearing surface radius. In another embodiment, individual bearing elements may be radially adjustable relative to the bearing ring to define and redefine the radius of a radial bearing surface.
