Minium Yield: More than 7%;
Material of ball: GCr15 (E52100);
Surface hardness of the ball: 60-66HRS;
Machining Tolerances for diameter of outside ring: +/- 1.2mm;
Coating: black for finishing coat, grey for primer;

Application:
Single row ball bearing turntables are for trailers and agricultural vehicles, connecting the A-frame to the trailer chassis. The turntable allows the axle to turn relative to the trailer frame transferring both the axial, and radial forces. The lower (outer) ring is bolted to the A-frame and the upper ring (inner) ring is bolted to the chassis.

Double row ball turntables guarantee optimum distribution of the axial and radial forces. This design has proven through years of different applications. Double row ball turntables are used in particular when the vehicle application requires both precision and strength in design and material.
