universal joints

1. WHAT IS A UNIVERSAL JOINT?
A universal joint, universal
coupling, U-joint, Cardan joint, HardySpicer joint, or Hooke's joint is a joint or
coupling in a rigid rod that allows the rod to
'bend' in any direction, and is commonly
used in shafts that transmit rotary motion. It
consists of a pair of hinges located close
together, oriented at 90° to each
other, connected by a cross shaft.

2. Expandable Universal Joints
Universal joints are used to transmit torque from one shaft to another which are offset to
each other. It is an ideal form of coupling two shafts when offset is unavoidable.
Universal joints are made from heat treated alloy steels for increased over load and
reliability. Precision machining ensures optimum performance under severe load
conditions.
UE expandable
OD from 20 to 63 mm bore. All universal joints are available with types plain bore, bore
with key way, square bore, hexagon bore. Available specially with other designs such as
longer lengths, with bellows, stainless material etc.

3. Single Universal Joint
Universal joints are used to transmit torque from one shaft to another
which are offset to each other. It is an ideal form of coupling two shafts
when offset is unavoidable.
Universal joints are made from heat treated alloy steels for increased
over load and reliability. Precision machining ensures optimum
performance under severe load conditions.
Types
UD Single joint
OD from 13 to 63 mm

4. Double Universal Joint
Universal joints are used to transmit torque from one shaft to
another which are offset to each other. It is an ideal form of
coupling two shafts when offset is unavoidable.
Universal joints are made from heat treated alloy steels for
increased over load and reliability. Precision machining ensures
optimum performance under severe load conditions.
Types
US Single joint
OD from 13 to 63 mm
