60N/Mm² WB702 CuSn8 CuSn6.5Bronze Wrapped Bearing With Holes

Description

WB702 bronze bushings with holes It is suitable for high load, lower speed applications like construction, Transport, and agriculture machinery.092 is deriving from 090; the difference between 090 & 092 is Indentations on the working surface, which substituted by Through-holes. These holes will allow greater capacity to collect lubricant, which builds up a lubrication film at the start of the movement and reduce the friction.

Bearings are thin-walled, rolled CuSn8 parts provided with depots for use with lubricants. They feature high-load capacity enabling compact, high-performing, low-maintenance bearing locations.

CuSn8/CuSn6 WB702 & WB700 Series bushings' biggest feature is the thin-walled structure, which does not occupy a large installation space. Sleeve material specially formulated high-density copper alloy strip. Compared with the traditional casting of copper, with high density, no gas shrinkage, carrying capacity, but also wear resistance, fatigue, and other advantages. Bushings manufactured using advanced tooling can be processed into a variety of engineering conditions apply oil hole, oil pit, sump friction surface strip, so that the sleeve can store a lot of grease in use, to extend the refueling interval, effective increased service life.

CuSn8/CuSn6.5 wrapped bronze bearings Features

1. Can tolerate high loads and blows
2. Works well, even in dirty environments
3. The lubrication depots, which perforate the bearing surface, give excellent lubricating characteristics
4. Good thermal dissipation
5. A broad range of dimensions is held in stock
6. Extends the interval between lubrications by 6-8 times, compared to traditional slide bearings

WB702 & WB700 bronze bushes are very easy to mount in various applications, thanks to their minimal bulk. In addition to being easy to mount, this type of bush is set apart by its excellent sliding capacity and simplified lubrication (long lubrication intervals).

Lubrication Pockets Self-Lubrication bushings phosphor bronze CuSn8 Wrapped bronze bearings must be lubricated with grease or oil on installation. High-quality lubricant is essential as it will reduce friction and wear by forming a film between the plain bearing and the shaft.

There are three basic variants:

As variant with rolled-in diamond-shaped lubrication recesses. This type is primarily designed to cope with cases where surrounding construction elements such as gear wheels are oil lubricated. Equally suitable are commercially available, pumpable greases or pastes.

also has lubrication recesses. However, these are filled with a solid lubricant, thus permitting operation without additional lubrication.

If greater demands are made on grease supply, with end-to-end lubrication holes would be the type to use. This variant is less suitable for oil lubrication due to its design.

Cusn8 Bronze Bushings

WB702 & WB700 bronze bushes are made from phosphorous bronze. These types of bushes, both cylindrical and flanged, are
cut from bronze sheets with a thickness between 1 and 2.5 mm. The main features of 700 and 702 bronze bushes are high load capacity, high thermal conductivity, and good resistance against bumps and oscillations. The composition is the same as wb-900, but with holes to collect the lubricant instead of indentations.
