The thin-wall construction of ROHS-compliant bimetal sleeve bushings offers a compact and efficient solution for precision bearing assemblies. These bushings are designed with a unique combination of materials that possess excellent wear resistance and self-lubricating properties.
The bimetal sleeve bushings are composed of a steel backing with an overlay of a softer, lubricious metal such as bronze or lead alloy. This combination ensures high strength and durability while providing smooth and reliable operation. The thin-wall design further reduces the overall size and weight of the bushings, making them suitable for applications where space is limited.
The ROHS (Restriction of Hazardous Substances) compliance ensures that the materials used in the manufacturing of these bushings are environmentally friendly and free from hazardous substances. This not only reduces the environmental impact of the products but also ensures compliance with international regulations and standards.
The precision machining process ensures that the bushings meet strict dimensional tolerances and surface finish requirements. This precision is crucial for applications where precise alignment and fit are necessary, such as in automotive transmissions, industrial machinery, and other high-precision equipment.
The compact size and superior performance of these ROHS-compliant bimetal sleeve bushings make them an ideal choice for precision bearing assemblies. They provide smooth and reliable operation with minimal friction and wear, resulting in longer service life and reduced maintenance requirements.

Advantage of Bimetal Bushings
low friction, high wear resistance
low coefficients of friction eliminate the
need for lubrication while reducing wear
and extending service life.
Maintenance-Free
Ideal for applications requiring long service
life without regular maintenance or operating
conditions with little or no lubrication.
Reduce shaft costs by eliminating the need
Lower System Cost
for hardening and machining grease paths.
Compact, one-piece construction provides
space and weight savings and simplifies
assembly.
Environmental
Greaseless, lead-free solutions comply
with increasingly stringent environmental
regulations such as the RoHS directive for
electrical and electronic equipment.
Bimetal Bushings Competitive Price,High Quality Standard SAE-797 bimetal bushing is based on steel and sintered with CuPb10Sn10 or CuSn6Zn6Pb3 as a lining layer. The strongest type of bimetal bushings and widely applicated in so many fields.
This type has the best performance within the range of Cu-Pb alloy constructured bushing.Thereforce it has a wide application and is mostly suitable for where is middle speed and high impact etc.
