Aluminium wire race bearing

Wire race bearing is a special structure bearing with the ring and raceway composited inlay. Bearing main body material can be choosen with some special material according to the operating conditions such as special aluminum alloy material, special copper and other metals or metal materials. Using quenched high performance special spring wire embedded in the bearing ring to serve as a bearing raceway with the characteristics of high precision, wear resistance, easy maintenance.
UWE designed and developed double row cylindrical roller wire raceway slewing bearing ,which was deliveried in March 2014, recognised by the height of the foreign users. The research and development of steel wire raceway slewing bearing ensure the bearing strong corrosion resistance, light weight, and it is applicable to cold, heat, and many other very dirty environment. Meanwhile the wire race bearing has characteristics of high precision operation, carrying capacity, impact resistance, high reliability.
Due to the high contact stress is mainly borne by steel wire, rings can be seperated. Bearing steel wire rolling can be removed to replace if damaged, the characteristics greatly reduces the cost of transportation, transportation efficiency, repair costs and downtime working time (rapid change in order to avoid delay in wartime aircraft).
This kind of bearing manufacturing is difficult, UWE technology belongs to the domestic advanced level, UWE aluminum wire race bearings are widely used in light machinery, medical equipment, military field and other special work areas, etc.

Wire-race bearings characteristics

Typical features of UWE wire-race bearings are the high-strength races for the rolling elements. A wire-race bearing system allows structural and material combinations as well as cross sections which are out of reach of any conventional antifriction bearing.Dimensions, cross sections and the ring material of the bearings can be optimally matched to all application requirements. Depending on their purpose, UWE wire-race bearings can be ball bearings, roller bearings.They offer decisive advantages over conventional surface-hardened slewing bearing designs like high running accuracy, low and uniform torque resistance even when distorted, resistance to corrosion, low weight due to the surrounding aluminum alloy bearing rings and low maintenance.

Aluminum Alloy Bearing

The surrounding bearing rings are not directly exposed to rolling friction, they do not have to be made from steel but can consist of non-ferrous metals, cast iron or synthetic materials. In particular, UWE aluminium alloy wire-race bearings with light alloy bearing rings have gained special importance.The same load carrying capacity as that of comparable steel bearings is achieved by using an aluminium alloy of high mechanical strength as ring material.Compared to steel bearings of identical cross sections,aluminium wire-race bearings weigh approx. 60 % less.High mechanical strength of this wrought aluminium alloy means that the gearing can also be cut directly into one or more bearing rings.A light alloy wire-race bearing can be made corrosion-proof and maintenance-free by using appropriate materials for the rolling elements and races. The corrosion behaviour of aluminium bearing rings can be significantly improved by a surface treatment.Weight comparison between light alloy and steel bearings equal in size with the same load-carrying capacity and an external diameter of 2200 mm.

Gamesa purchasing manager will visit UWE

UWE will be visited by Gamesa(global technological leader in the wind industry) purchasing managers Bob and Peter.They will come on 30 July. All UWE staff  highly value this chance. After Vestas visit on April, UWE has perfected management system, improved quality control and optimized test equipment, and we are confident that our strength will earn this big customer.
Wind power bearings need high precision and long service life, 20 years is a required lifetime for the wind turbine generator, it is also required by yaw bearing and pitch bearings as the mounting cost is too high. A full set of quality control documents,raw material quality certificate,finished product inspection will ensure the high and strict requirement.
UWE all colleagues are here waiting for everyone coming and having disscusion.

UWE is planing to do DNVGL certificate for slewing ring

After Vestas engineer visit to UWE, we begin to perfect management system, improve quality control and optimize test equipment. We gained another big customer ZWZ, we supply 1.5 MW blade bearing manufacturing services for them and they come for inspection.
Fortunately, Gemasa purchasing managers also will come on 30-31 July for wind power bearings. It is quite a good chance for UWE.
In addition, We are planing to do DNVGL certificate, and getting contact with the organization.This is our first time to do this certificate, so we have to gain a long-term slewing ring supply-demand relationship,especially wind turbine bearings. 
With the DNVGL certificate, we could help more customer to do slewing ring certificate and will make customer be more confident about UWE slewing bearings.
