TURNTABLE BALL BEARINGS. AGRICULTURAL

Applications and use of ball turntable bearings

Aline Tradings range of turntable ball bearings are used in many applications; amongst the most important we could mention are agricultural trailers, irrigation systems and airport luggage carriers.

In the applications on vehicles, ball turntable bearings transmit not only axial load, but also radial load and torque.  In other applications they transmit mostly axial load.  The turntable bearings in the L range are suitable for use on light vehicles with a speed of up to 25 Km/h Turntable bearings in the N-P-T ranges can be used on vehicles with a speed of up to 40 Km/h. The following information includes the limit values of axial load capacity for a speed of 25 Km/h . For applications with speeds above 25 km/h and up to 40 km/h,, the load capacity decreases.
For applications with speeds of less than 25 km/h, the load capacity may increase up to a maximum of 40%, depending on the size & type of bearing.
In these cases further technical information may be required to determine the acceptable load capacity of the turntable bearing.
The values shown are valid for use on vehicles that circulate on the roads and under conditions of conventional transport.


Construction of ball turntable bearings.

The turntable basically consists of 2 flange rings which have a semi-circular shaped rolling track. The two rings are securely assembled by inserting steel ball rollers. The units are then thoroughly greased before prime painting and final inspection.


Conditions and Supply of ball turntable bearings

The turntable bearings are supplied with a protective coating of black rust-proofing paint, this is sufficient to adequately protect the product until the end use. The turntable bearings leave the factory already greased and have greasers on the outside. The turntable bearings do not have holes for fixing bolts.
