Oiles Toughmet D
Sintered bronze bearings consisting of a steel back
and uniformly dispersed wear resistant lubricants.
Features
Superior durability and stable low coefficient of friction where lubrication is
present.
Able to handle reciprocating, oscillating, and intermittent motion where oil
film is difficult to be formed.
Thin walled configuration for compact design.
Dramatically reduces lubrication intervals.
Possesses high load carrying capacity, wear resistance, and seize resistance.
Electric coductivity.
Available in various standard and custom sizes.
