Abstract
Abstract A plain bearing comprising a support and a galvanically deposited bearing alloy deposited on said support in a thickness of about 0.01 to 0.1 mm from a bath containing metallic fluoroborates. The bearing alloy is a copper-free alloy of only tin, antimony and lead and consisting essentially of 16 to 40% by weight tin, 8 to 11% by weight antimony and the balance lead. The support comprises a steel support covered with lead or tin-bronze and a nickel containing barrier layer.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
58 words
A plain bearing comprising a support and a galvanically deposited bearing alloy deposited on said support in a thickness of about 0.01 to 0.1 mm, said bearing alloy being a copper-free alloy of only tin, antimony and lead and consisting essentially of 16 to 40% by weight tin, 8 to 11% by weight antimony and the balance lead.
Claim 2
Dependent Claim
58 words
A plain bearing comprising a support and a galvanically deposited bearing alloy deposited on said support in a thickness of about 0.01 to 0.1 mm, said bearing alloy being a copper-free alloy of only tin, antimony and lead and consisting essentially of 16 to 40% by weight tin, 8 to 11% by weight antimony and the balance lead.
Claim 3
Dependent Claim
28 words
The plain bearing defined in claim 1 wherein said alloy is an alloy of 35 to 40% by weight tin, 10% by weight antimony and the balance lead.
Claim 4
Dependent Claim
16 words
The plain bearing defined in claim 1 wherein said thickness is between 0.020 and 0.050 mm.
Claim 5
Dependent Claim
25 words
The plain bearing defined in claim 3 wherein said alloy consists essentially of 35 to 40% by weight tin, 10% by weight antimony, balance lead.
Claim 6
Dependent Claim
34 words
The plain bearing defined in claim 4 wherein said support is steel provided with a coating of tin or lead-bronze, and a barrier layer containing nickel onto which said bearing alloy is galvanically deposited.
Claim 7
Independent Claim
59 words
A method of making a plain bearing which comprises the steps of: galvanically depositing upon a support a bearing metal layer free from copper, composed only of tin, antimony and lead, and consisting of 16 to 40% by weight tin, 8 to 11% by weight antimony and the balance lead in a thickness of 0.01 mm to 0.1 mm.
Claim 8
Independent Claim
59 words
A method of making a plain bearing which comprises the steps of: galvanically depositing upon a support a bearing metal layer free from copper, composed only of tin, antimony and lead, and consisting of 16 to 40% by weight tin, 8 to 11% by weight antimony and the balance lead in a thickness of 0.01 mm to 0.1 mm.
