Bronze Bearings.
Sintered Bearings.
Steel Rings.
Our self-lubricating bearings are given on the chassis of the walking mechanism, body elements and hydraulic components. Includes bimetallic lubrication of rolling bearings, self-lubricating metal-based bearings and self-lubricating plastic rolling bearings.
These bearings have material under high load, excellent wear resistance and anti-dust effect, and the technology of self-lubricating bearings allows much longer maintenance cycles, improves the use of equipment, reduces maintenance costs.
TOP BEARINGS offers a comprehensive selection of sleeve bushing to meet the world’s most demanding surface engineering needs.
We manufacture metal-polymer, engineered ptfe bushing, fiber reinforced composite stainless steel 316 or 304 bushing, metal and bimetal bearings and polymer coatings along with a range of supporting assemblies, bushing blocks and thrust plates.

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 withCuPb10Sn10or 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.
The bimetal bearing specialist with custom material manufacture design size
TOP BEARINGS has been proving its vast experience and technical know-how in manufacturing and marketing bimetal bearings bushings and drive units. Benefit from experts who seek the perfect sliding bearing solution for you, designed for your special applications.
CuPb10Sn10 is a higher lead content giving it a better advantage for higher rotational speeds. Also, the bimetal sliding layer has lubrication pockets that are also suitable for oil lubrication and thus allowing this bushing material to run at much higher rotational speeds.
