GlacierVandervell has been a leader in the design, development and manufacture of high
quality plain bearing materials for the last 100 years. We have also been the leader in
transforming those materials into custom designed precision bearings, bushes and thrust
washers.
The working environment of a plain bearing requires a combination of material
properties which may be divided into soft and hard phase characteristics.

FEATURES

The addition of 20% tin gives AS15 optimum seizure resistance whilst still maintaining excellent mechanical properties. Superior tensile strength is achieved by cold working and
annealing treatments which give continuous tin along the aluminium grain edges but not along the grain faces. This strong alloy matrix contains a reticular tin structure.
AS15 is lead free and is now a standard for passenger car main bearings.

20% aluminium tin with increased fatigue strength.

An aluminium/tin material containing silicon which shows excellent performance in crankshaft thrust washer applications.

Glacier AS1241 was developed as a material capable of withstanding high loads without the need for an overlay. It has a similar reticular structure to AS15 but silicon is associated
with the tin network. Copper is present within the aluminium phase as a solution hardener. It is lead free and mainly used for passenger car connecting rod bearings.

AS154 consists of silicon in an aluminium matrix. Copper and magnesium are also present within the aluminium phase as solid solution hardeners. The material has high fatigue
strength and excellent corrosion resistance. It is used overlay plated.

A material similar to AS1241 which can be supplied on a global basis. Its main use is for passenger car applications.

Closely controlled rapid solidification, multi layer powder rolling and a continuous strip solution heat treatment process results in a uniform and homogenous distribution of lead in a
strong aluminium alloy matrix. F85 has excellent ability to endure prolonged service cyclic loads without distress and gives similar performance to AS1241.

F96 has the same composition as F85 but is annealed to provide improved seizure resistance and conformability in bush and washer applications.

VP2 is a lead bronze material which is continuously cast onto steel strip. Casting and quenching conditions are controlled in order to produce a microstructure with vertically orientated
bronze columns. This gives the bearing material its superior strength increasing its compressive load capacity. When plated with lead indium it has become the favoured material for
racing engines. The combination of a lead tin alumina overlay with VP2 improves wear resistance by a factor of two when compared with a lead tin copper overlay. In addition
the shaft conditioning properties are enhanced and fatigue resistance is improved.

VP1 differs from VP2 in its reduced lead and increased tin contents, giving it a higher load carrying capacity. VP1 is used unplated in bush applications and overlay plated in very
highly loaded half bearing applications.

VP3 is similar to VP2. It is supplied with either a lead tin copper or lead indium overlay.

Very high shock and load carrying capacity and high temperature resistance. Excellent for cup drawn seamless bushes such as tappet rollers and spring eye bushes.

A general purpose bush alloy. Good for high speed high load applications with very good compatibility and conformabilty without sacrificing strength. Good for applications involving
some foreign matter and/or misalignment. A good choice for components that will be ball indented or graphited.

VP10 is a very high strength lead bronze. It has excellent wear and corrosion resistance and its load carrying capacity and shock resistance make it ideal for small-end bushes.

SP can be used for bushes or, when plated with lead tin or lead tin copper, for half bearings.
Good compatibility and embeddability. Used unplated for bushes and thrust washers subjected to intermediate oscillating and rotating loads. Used for heavy duty bearings when plated.
SX is a sintered material similar to VP2 but with a higher tin content. It is used unplated in bush applications or with a lead tin overlay in half bearings.
Glacier SY is the sintered equivalent of VP10.
Thin sintered material has a high load capacity and, when overlay plated, good conformability, embeddability and corrosion resistance.
A material designed to have excellent conformability, without an overlay, and for use in light duty bush applications.
