These Universal Joints fit the mechanical linkage needs of multiple applications, including those in the textile industry. Needle bearing universal joints are sealed and lubricated cross & bearing type joints with rigid axial stiffness for push & pull loads. This design is ideal for handling the rotation and axial load of yarn at the end of a spindle. In addition, block style universal joints are well suited for high heat applications - e.g. where a joint is used right next to a hot polymer pump. These Universal Joints are packed with high-temperature lubricants to enhance operating life.

These Universal joints are available in steel or in thermoplastic body members. Universal joints made of steel have the maximum load-carrying capacity for a given size. Universal joints with thermoplastic body members are used in light industrial applications in which their self-lubricating feature, lightweight, negligible backlash, corrosion resistance, and capability for high-speed operation are significant advantages. Universal joints of special construction, such as ball-jointed universals are also available. These are used for high-speed operation and for carrying large torques. They are available both in miniature and standard sizes.
These Universal joints have the following advantages:
1.Low side thrust on bearings.
2.Large angular displacements are possible.
3.High torsional stiffness.
4.High torque capacity.
They have the following disadvantages:
1.Velocity and acceleration fluctuation increases with operating angle.
2.Lubrication is required to reduce wear.
3.Shafts must lie in precisely the same plane.
4.Backlash difficult to control.
