Wrapped bronze bearings are specifically designed for use in
hoisting machines, where they play a crucial role in ensuring
smooth and reliable operation. The bronze material used in these
bearings is known for its excellent wear resistance, high strength,
and corrosion resistance, making it a suitable choice for demanding
industrial applications.
The wrapping construction of these bearings provides additional
stability and durability. The bronze material is wrapped around a
core structure, creating a strong and resilient bearing that can
withstand the heavy loads and repetitive motion typical of hoisting
machines.
Wrapped bronze bearings also exhibit good self-lubricating
properties, which helps reduce friction and wear during operation.
This results in lower maintenance requirements and extended service
life for the bearings.
In addition, wrapped bronze bearings are precision-engineered to
fit the specific requirements of hoisting machines. They are
designed to ensure proper alignment and load distribution,
minimizing stress and wear on the bearings and the surrounding
components.
Overall, wrapped bronze bearings are an excellent choice for
hoisting machines, providing superior performance, durability, and
reliability in demanding industrial environments.

Sleeve Bearings · Straight – Flange Sleeve Bearing(WF-WB700 &
WB700)
The bearings are manufactured of a cold formable homogenous bronze, which because of this will obtain exceptional material
properties. The execution of the flange permits that the bearing
also can carry axial loads. The standard sizes are fitted with diamond-shaped lubrication
indents on the bearing surface.
These indents serve as lubricant reservoirs I .a. to rapidly build
up a lubrication film in the moment of start and therewith reduce the start friction. The properties of the WB700-material, tog with the procedure of
wrapping and calibration, make this type of bearing especially
suitable for constructions, where medium or high loads and relatively slow movements are
occurring
WB700 is a kind of bushes wrapped by bronze strip. The bronze is made as
to the particular formulation with high specific and gravity, and on its surface may be incorporated with spherical or
diamond-shaped indentations or/and oil grooves as required by
customers. It is of high load capacity and long life, in place of traditional casting bronze bush. It is cheaper and
more compact. It is widely applied in hoisting machines and other
construction machines, automobiles, tractors, trucks, machine
tools, and some mineral engines.
Advantages:
1. Lead-free and fully recyclable. Less expensive than a machined
bushing.
2. Minimal space required.
3. Lighter in weight than machined bushing or roller bearing.
4. High stability under load, therefore particularly suitable for
oscillating bearing.
5. Lubrication grooves are coined into the metal, and any shape
desired is possible.
6. Grease depots for long-term lubrication.

WF-WB700 Flanged Bushing
WF-WB700 Flanged Bushing is a kind of slide bearing in split
wrapped bushing. It is made of CuSn6.5 or CuSm.The bronze is made
as a particular formulation with high specific and gravity.
WF-WB700 Flanged bushing offers the following additional advantages:
1. A single bushing and take both radial and axial forces.
2. A single bearing element is needed to replace both thrust washer
and cylindrical bushing.
3. High stability.
4. No fixing of thrust washers.

Bronze Bushing Structure Characteristics & Applications
Bronze Bushing wrapped bronze bearing is made of tin-bronze CuSn8 with its surface punched with diamond oil sockets that are
preserved for oil saving. It has good anti-fatigue, anti-erosion anti-abrasion, and load
capacity. The products are widely applied in conditions of heavy
load but low running velocities, such as on agricultural, building,
and engineering machines.
Product Benefits
1. Saving a large amount of bronze material and save the working
hours normally spent on lathing the bronze bushing.
2. Compared with lathed bushings and roller bearings, it is lights
and more cost-effective.
3. Various holes and dents can be made on the frication surface for
grease storage, prolonging the lubrication interval to 5 times as
long as required by the bronze bushing.
4. Extremely high load sustainability, especially suitable for
coarse abrasion surfaces.
Standard products available: straight bushings, thrust plates, and
pressure bearings.
Non-standard products available: straight bushings, thrust plates, planks, bearing bushings, slide
plates, and steel bushing assembly.
Bronze Bushing material
High-density bronze is rolled into shape or oil bags and oil holes
are specially integrated into the inner surface to reduce the
wearing and prolong the service hours. Besides, it has excellent
anti-corrosion functions.
