David from Canada
    Our company import the bronze gleitlager from viiplus china,viiplus professional team makes sure customs clearance is always smooth. They provide an accurate bronze bushing classification, handle all the paperwork,We have received the self-lubricating bronze bushings. They look well done and the high quality.
    Valerie from California
    We import the bronze gleitlager from China to under the incoterm FOB shanghai, sometimes by Air. viiplus is a very good bronze gleitlager supplier, they are very professional and patient, after we inform the new order, they will manufacturer bronze gleitlager in time and give us the schedule , and then we just need to receive the bronze parts

These bronze bearings have been developed to for slow speed, high load applications, especially suited for oscillating motion and are perfect for the construction, mining/quarrying, agriculture and automotive industries.

Our Viiplus range of plain bearings are avialble with lubrication pockets, thru-holes and grooves. This range is available in metric sizes only.

Our in-house machining service is able to produce non-standard sizes to suit specific customer requirements.

Wrapped bronze bushing is made of tin-bronze CuSn8P with its surface punched with diamond oil sockets which are preserved for oil saving. It has good anti-fatigue, anti-erosion anti-abrasion and load capacity.


CuSn8 bronze material wrapped thin wall oilless bushing




lagerbuchse are made entirely from phosphor bronze CuSn8. CuSn8 is characterized by the purity of the alloy with only a very low level of impurities. Wrapped bronze bearings are produced from strips that are subsequently wrapped and calibrated.




Wrapped bronze bearings must be lubricated with grease or oil on installation. A good quality lubricant is essential as it will reduce friction and wear by forming a film between the plain bearing and the shaft. For heavily contaminated applications, we recommend sealing off the bearing. This will protect both the bearing and the lubricant.



1. Easy for fitting and lubricating
2. High load capacity
3. Inner Diameter machineable parts are available against order
4. High level thermal conductivity
5. Minimum overall dimensions
6. Chemical resistance.
Initial pre-lubrication at assembly required... Chemical Compositions lagerbuchse are wrapped from a cold formed homogenous bronze (CuSn8) with exceptional material properties. The standard sizes are fitted with diamond shaped lubrication indents in the bearing surface. These indents serve as lubricant reservoirs to rapidly build up a lubrication film at the start of movement and thereafter reduce the running friction. The material is suitable for construction and agricultural machinery applications.


Lagerbuchse | Metric Size


Viiplus lagerbuchse are available in metric sizes as straight or flanged bushings. They are wrapped from strips and calibrated. These bushings are an excellent solution for dirty environments where high levels of contamination make relubrication necessary. They are resistant to shock loads and vibrations at slow speeds.

The diamond-shaped lubrication pockets in the sliding surface need to be filled initially with grease. A good quality lubricant reduces friction and wear by separating a bronze bushing from its shaft. To protect the bushing and lubricant in highly contaminated environments, viiplus recommends using seals.




Wrapped bronze bearings are especially suited to severe operating conditions where frequent maintenance is not possible. Common applications are:

  • Agricultural vehicles
  • Lifting gear
  • Offshore
  • Excavators




– High load capacity
– Works well in dirty environments
– Wide temperature range
– Easy to assemble
– Grease pockets as lubrication reservoirs

Main Factors that Influence the Service life of the Bushing

1).PV Value
PV value is an effective criterion to calculate the service life of TCB900/TCB902. If there is need to prolong the service Life, PV value must be reduced.
2).Environment Temperature
Service life of the TCB900/TCB902 will shorten in higer ambient temperature .
Service life of TCB900/TCB902 can be greatly improved if its mating axis is made of chrome-plated stainless steel with hardness more than 50HRC and surface roughness among 0.4~0.63.
