DIN 808 G

Universal joints with friction bearing

Assembly :
– Execution B: plain holes.
– Execution K: holes with DIN 6885/1 keyway.
Example 1 :
Output to be transferred N = 0.65 kW R.p.m. n = 230 min-1 Angle of inclination ß = 10° Correction coefficient k = 1 Indicative output N’ = Nominal output N Intersection point P is arrived at from 0.65 kW and 230 min-1 (which corresponds to a torque of 27 Nm). The next size up universal joint corresponding to point P is in the model with a diameter d1 = 25.

8688_BJT__p_i

BJT.

Rod ends

Features and applications :
BJT. rod ends are remarkably suitable for rotary, oscillating and linear movements even in aggressive environments and when water or humidity, fine dusts, dirt, fabrics, machining residues are present.
The shaft rotary movement can take place directly on the inner diameter of the spherical cap, made of self-lubricating material.
Features of the technopolymer rod ends:
– totally corrosion resistant even in the presence of chemicals;
– good mechanical strength to the applied loads;
– very low weight combined with high stiffness;
– maintenance free;
– compensation of possible misalignments;
– absorption of vibrations and transverse stresses;
– noise minimization.
Material :
Glass-fibre reinforced polyamide based (PA) technopolymer. Resistant to solvents, oils, greases and other chemicals.

8079_GN_751_DIN_71752_p_i

GN 751 DIN 71752

Fork jointsFork heads

Assembly :
GN 751 fork joints consist of a DIN 71752 fork head.
Pin hole (d2) with standard thread.
– Type B: fork pin with snap-on spring.
– Type KL: fork pin with KL-shaft safety.
– Type SL: fork pin with SL-shaft safety.
Features and applications :
Fork joints GN 751 in aluminium consist of a fork head according DIN 71752 and a fork pin with KL-shaft safety or SL-shaft safety.
Owing to the anodized coating of the fork head and of the bolt, the bearing is virtually non-wearing.

FJT.

Forks

Assembly :
Threaded hole.
Features and applications :
FJT. forks are remarkably suitable for actuation even of pneumatic cylinders, when water and humidity are present (totally corrosion resistant).
Features of the technopolymer forks:
– totally corrosion resistant even when humidity and chemicals are present;
– good mechanical strength to the applied loads;
– very low weight combined with high stiffness;
– resistant to continuous washing cycles with solvents and detergents, so they are suitable, for example, in applications in the food and pharmaceutical sectors;
– excellent shock-absorbing features.
– noise minimization;
