14.8.8.3. Who makes bearings

THE GENERAL DATA

Complexity of all circle of the problems connected with creation of high-quality automobile bearings of sliding, has led to that their manufacture has gradually passed to specialised firms. Abroad many their such firms simultaneously let out also other details of engines, and deliveries go both on conveyors of car factories, and to spare parts. Some firms such are a part of known transnational industrial and commercial and industrial corporations. From world manufacturers of bearings for engines it is necessary to note first of all firms Kolbenschmidt (KS), Glyco, TRW, Sealed Power, Glacier, Clevite, Bimet. Last years bearings have started to do and such firms – "coryphaeuses", as Mahle and Goetze. Among "young" it is necessary to mention the specialised firm King (Israel) which has begun release of bearings in the early eighties.

The majority of the listed manufacturers lets out the huge nomenclature of bearings and delivers the production in spare parts everywhere, including on our market (through dealers or the wholesale trading companies). Basically, of course, it is bearings for foreign engines – European, Japanese and American.

It is possible to find loose leaves in sale both standard, and the various repair sizes (as a rule, no more than 0,75 mm) on the majority of widespread models "Audi-folksvagen", the BMW, "Mercedes", "Ford", "Opel", "Fiat", "Tojota", "Nissan", "Mitsubisi", "Mazda" etc. On less widespread models, and also in need of purchase of loose leaves большего the repair size usually it is necessary to make out the order and to wait on the average for 5-10 days (at different trading firms these terms are various).

Quality of such production usually does not cause doubts neither on geometry, nor on materials. Though, if there is a choice and doubts in to what firm-manufacturer to prefer, it is necessary to mean the following. Such firms as, for example, Kolbenschmidt, Glyco, Glacier are one of the basic suppliers of mass production. At purchase of their products it is possible even to receive the same loose leaves that stood on the engine "since a birth". The difference will be only in absence on new details of an emblem of firm-manufacturer of the car. By the way, search "native" (or so-called original) loose leaves of the repair sizes can appear problematic. Not all automobile firms deliver repair loose leaves in spare parts, and the price of loose leaves in "original" packing, as a rule, considerably above, than directly from their manufacturer.

Loose leaves of other, less eminent firms are usually cheaper, though on quality to find out differences difficultly. Moreover, if there is a choice here it is possible to try to consider and car service conditions. So, rather cheap loose leaves, strangely enough, resist to bad quality oils and маслофильтрам, "walking" on our shops and the markets, than more expensive сталебронзобаббитовые is slightly better. It use practice under repair steel-aluminium loose leaves of firm "King" instead of regular бронзобаббитовых, in particular, has shown – such replacement does not put a damage of reliability of engines, but allows to save considerably.

Some of the listed firms let out loose leaves and for our cars. In our market it is already possible to find these products for engines VAZ of manufacture of firms Clevite, Bimet and Glacier. Certainly, they aloud are more expensive than the domestic. However to save on loose leaves at repair of domestic motors it is not necessary. Comparison with import production domestic usually does not maintain. Deviations on a thickness at some our commodity copies reach 25–30 microns instead of 8 microns, regulated by the admission. As a result after зажатия a cover внутрення the bearing surface gets the wrong form at which, for example, the backlash in 0,07–0,09 mm in one section of the bearing can even pass in a tightness in other.
