A slide bearing can include a metal support, a primer layer, an adhesive layer applied directly thereto, and a sliding layer applied to the adhesive layer. The primer layer can include an oligomeric condensate of at least one silanol selected from the group having the formula:  The moieties Rand Rcan be the same or different. The moieties Rand Rcan be selected from the group consisting of methyl, ethyl, n-propyl, i-propyl, and a functionalized alkyl group R'&#x2014;(CH)&#x2014;, wherein z is at least 1. Slide bearings comprising a primer system based on silanol oligomeric condensates show improved peel strength than their analogous slide bearings lacking the primer system.

Slide bearing comprising a primer system as adhesion promoter

A slide bearing can include a metal support, a primer layer, an adhesive layer applied directly thereto, and a sliding layer applied to the adhesive layer. The primer layer can include an oligomeric condensate of at least one silanol selected from the group having the formula: 

Slide bearings and methods of producing slide bearings are disclosed. The slide bearing has a metal support and a sliding layer. No other layer is in contact with the sliding layer. The sliding layer is applied directly to the metal support. The sliding layer comprises a mixture of at least two polymers P1 and P2, wherein P1 is a fluoropolymer. P2 is a non-fluorinated thermoplastic polymer.

Maintenance-free slide bearing with a combined adhesive sliding layer

Slide bearings and methods of producing slide bearings are disclosed. The slide bearing has a metal support, an adhesive layer and a sliding layer. The adhesive layer is applied directly to the metal support. The adhesive layer comprises a blend of at least two fluoropolymers P1 and P2, wherein P1 is selected from perfluoroalkoxyethylene (PFA) or tetrafluoroethylene-hexafluoropropylene (FEP). P2 is different from P1 and can be a fluoropolymer.

Maintenance-free slide bearing with FEP or PFA in the adhesive layer

A maintenance-free plain bearing includes a metal support, an intermediate layer applied directly thereto and a sliding layer applied to the intermediate layer. The intermediate layer includes at least one functionalized thermoplastic polymer having functional groups of the formula &#x2014;COOH and/or &#x2014;COOR, where the radicals R are cyclic or linear organic radicals having from 1 to 20 carbon atoms.
