9)Very low weight.

 2.Sizes

Available with Metric and Inch size.Metric - Bore size 2mm-30mm

Inch    - Bore size 0.1900"-1.000"

3.Application Temperatures

LDK bearing elements can be used in temperatures from -30 to +80 degree.

MAXIMUM	-30 DEGREE
MAXIMUM,LONG TERM	+80 DEGREE
MAXIMUM,SHORT TERM	+120 DEGREE

4.Chemical Resistance 

The moisture absorption of LDK is approximately 1.3% of weight standard atmosphere. The saturation limit in water is 6.5%.This must be taken into account

 for these types of applications .LDK all plastic polymer are resistant to week alkalines,weak acids and fuels,as well as all types of lubricants.

Medium                         Resistance

Alcohol	Resistant
Chlorinated hydrocarbons	Resistant
Ester	Not Resistant
Greases,oils	Resistant
Ketones	Conditionally Resistant
Fuels	Resistant
Weak acids	Conditionally Resistant
Strong acids	Not Resistant
Weak alkalines	Resistant
Strong alkalines	Conditionally Resistant

 5.UV Resistance

1.The corrosion resistance of the LDK bearings give them special value for outside applications.

2.LDK bearing elements are permanently resistant to UV radiation.Asmall change in colour(dark coloration)of the spherical ball due to UV radiation does not effect the mechanical ,electrical or thermal properties.

 6.Loads

1)The load capacity of the maintenance free LDK bearing elements is very high at normal ambient temperatures.LDK bearing elements absorb high forces and weigh only a fifth of the traditional,metal bearing housings.The excellent dampening properties are based on the fact that the polymer material of the two part bearing can absorb vibrations fifferently than steel.

2)However,plastic specific properties,such as dependence on the temperature and behaviour under long term stress,must be taken into consideration when using LDKbearings.The load capacity of therod end bearing should therefore be checked

in a performance test,particularly of they are to be used under continuous high loads and at elevated temperatures.

 7.Coefficient of Sliding friction and speed

1)One important advantage of LDK spherical bearings is that rapid,rotary movements of  amounted shaft take place directly in the spherical portion,made of special plastic polymer,in metallic rod ends,rotary motion takes place between the race and the spherical bearing.High speeds can be achieved with LDK bearings.

2)LDK bearings area used in such a way that the angular movements of the spherical bearings takes place at the outer diameter.In contrast,rotations of the shaft are supported directly in the ID.of the sphercial portion.
