Double Ball Race Turntables

In a system comparison

The quality of WONDEE double ball race turntables is superior to conventional single race systems. Double ball races ensure optimal distribution of the axial and radial forces incurred. The superior design of this system, renowned for many years, is demonstrated by the daily use of draw-bar trailers, semi-trailers, heavy load transporters and special transportation vehicles. WONDEE turntables are used above all where vehicle construction places the highest demands on design and material.

In addition to this the WONDEE product range includes complete frames and A-frame full trailer draw-bars.

Optimal transmission

WONDEE turntables are equipped with supporting and retaining ball races between the upper and lower rings.

• The axial forces on the turntables are accepted vertically via the large supporting ball bearings.

• The horizontal tensile and compressible forces incurred are accepted by the smaller retaining ball bearings.

• The moment forces, resulting from braking and centrifugal forces, are mutually accepted by the supporting and retaining ball bearings.

• The retaining ball bearings connect the upper and lower turntable rings.

Absolutely reliable

The design principle ensures maximum reliability because the active axial and radial forces are distributed between the two ball races of WONDEE turntables.

• Special materials and production methods are selected to achieve high quality levels. The turntable profiles, which are made of hardened steel, are forged under heat, butt-welded and then calibrated under normal temperatures. This process ensures reduced material tension so that they can be used under extreme operational conditions.

Economy through durability

WONDEE turntables guarantee a minimum of idle time due to their long service life.

• The ball race is additionally hardened when the ball bearings are under load.

• The ball races are permanently protected against dirt and dust by a multi-lip seal.

• The sum of all these advantages ensures reliability, smooth operation and maximum life expectancy.
