Characteristics
Bimetal bearing with steel backing and leaded bronze overlay.For lubricated applications with plain sliding layer Suitable for oil and grease lubrication
Vailability
Bearing forms made to order: cylindrical bushes, thrust washers, sliding plates, customized bearing designs
Bronze Bearings. Sintered Bearings. Steel Rings.
Construction machinery
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.

TOP BEARINGS has manufacturing, sales, service and supporting assemblies, bushing blocks and thrust plates.
Bushing Application served include:
— Aerospace — Automotive — Industrial — Agricultural — Construction — Oil and Gas — Energy — Fluid Power
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 bearing profile, Bimetal bushing Can be customized
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.
Wrapped composite sliding bearing, Copper-plated or tin-plated steel/bronze, DIN 1494 / ISO 3547, Maintenance-free, With lubrication pockets or groove design
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.
ZHEJIANG TOP BEARINGS CO., LTD. is a manufacturer and distribution of sliding bearings. Our
