VTC International

ZWZ has 9 manufacturing bases, 10 business divisions, 26 wholly-owned and holding branch companies and subsidiaries globally.
ZWZ owns two bearing brands, ZWZ and KRW. The company adopts international standards and can produce more than 20,000 specifications of bearing products in ten categories with various precision levels from 20mm inner diameter to 16m outer diameter, which are mainly used in industrial equipments, railway transportation, automotive vehicles, wind power and special applications.
ZWZ has a national large-scale bearing engineering and technology research center, a national enterprise technology center, a bearing inspection and test center, and overseas R&D centers in Europe and the United States, that has established 8 technology innovation platforms concerning simulating calculation, materials, lubrication, inspection and so on.

There are two row designs: single-row bearings and double-row bearings. Most ball bearings are a single-row design, which means there is one row of bearing balls. This design works with radial and thrust loads. A double-row design has two rows of bearing balls.

Deep groove ball bearings are particularly versatile. They are suitable for high and very high speeds, accommodate radial and axial loads in both directions and require little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from ZWZ in many designs, variants and sizes.

A tapered roller bearing is a unit that consists of both tapered raceways (inner and outer rings), and tapered rollers. The construction is intended for combination loads, such as dual acting axial and radial loads.

Cylindrical roller bearings (CRBs) have a simple structure with their cylindrical rollers in linear contact with the raceways. They offer high load capacity under primarily radial loads. Low friction between the rollers and ring ribs makes these bearings suited for high speed rotation.

Single row deep groove ball bearings are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types.

Single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds. Having two integral flanges on the outer ring and no flanges on the inner ring, N design bearings can accommodate axial displacement in both directions. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
