They all consist of a star wheel core and 2 half-joints with fork ends. Between the pins of the star wheel and the holes of the forks, 4 wear-resistant sliding bushes (for G series) or roller bearings (for H series - high speed) are fitted in. 

Neither lubrication nor maintenance is required for H series (high speed joints with roller bearings) as their bearings are lubricated for life.
Joints with plain bearings - G series - are for middle-low speeds and where there are shock loads.
For high speeds and relatively low torques types with roller bearings (H - HB) are recommended.
Both versions offer high efficiency, silent running, low friction coefficient at competitive prices.
All rubbing surfaces are hardened and ground.
Maximum working angle is 45° for single joints and 90° for double joints.
Maximum speed is 1000 R.P.M. for G series, while H series can reach 4000 R.P.M.
All these joints are also supplied in telescopic version.
