High Quality GMB GUM73 Universal Joint Cross Bearing  

Tape Universal joint consists of spider(cross) and 4 grease-filled roller bearings.  It can transmit large torque at low friction.  Spider with journal pegs and bearing cases as outer ring were hot forged or cold formed and machined.  They are later carburized in furnace so that increased ruggedness and wear resisitance are obtained.  Parts are finally ground to designed size under severe tolerance.  Oil seal as well as dust cover are also in use to protect internal journal area from intrusion of foreign material.  Variety of grades and materials are selected to repond to extreme conditions such as very hot / very cold temperatures. red roller bearings have tapered inner and outer ring raceways and tapered rollers. They are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axis to provide true rolling and low friction. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle . The size of the angle is indicated by the calculation factor e : the larger the value of e, the larger the contact angle. A single row tapered roller bearing is typically adjusted against a second tapered roller bearing. 
Single row tapered roller bearings are separable ,i.e. the inner ring with roller and cage assembly (cone) can be mounted separately from the outer ring (cup).
