P series joints are precision products consisting of forked hubs and solid pins machined from one piece, to have an extremely compact central block.
Types E are with sliding bushes while type H has needle roller bearings. It’s produced in one only version:
» P series according with DIN 808.
Joints with plain bearings are available in 2 versions:
» E series according with DIN 808.
» EB series according with DIN 808/7551.
Joints with roller bearings are available in 2 versions:
» H series according with DIN 808.
» HB series according with DIN 808/7551.
Every model is made by 2 hubs with forks and a central block.
Between pins and bores there are:
» P series: 4 bearings with solid pins.
» E series: with sliding bushes.
» H series: with needle roller bearings.
In the central blocks of P and E series there are the holes for lubrication.
For the H series (for high speed applications) no lubrication is needed, because the roller bearing are maintenance free.
P series joints are designed for high precision and lifetime applications.
E series joint with sliding bushes are used for low-medium speed and when some shock load can occur.
For high speed and medium torque, we suggest the type H with roller bearings. The maximum working angle is 45° for single joints, 90° for double joints. The maximum speed is 1000 rpm for P and E series, 4000 rpm for H series. Every execution can be supplied with extendable shaft.
