To assure you of prompt service, Curtis stocks
at all times 14 sizes of joints with solid and
bored hubs.
Standard alloy steel Curtis Turn-Key Joints
are also available from stock, and are ready for
installation with standard bores, keyways and
set screws already installed.
Curtis Alloy Steel Joints employ the use of
leaded alloys for all major component parts of
their joints. The use of leaded materials greatly
improves the machinability of these alloys.
Curtis Alloy Steel Joints feature 41L40-grade
steel for all forks. Forks of 7/8" diameter and
larger have induction-hardened bearing manufacturers areas for
strength and durability. The body (hubs) of the
joints remain in an annealed state, which affords
free machinability. Center blocks and pins are
machined from 86L20 alloy steel. Center-blocks
and pins are carburized and case hardened to generate
superior wear characteristics yet remain ductile,
thereby enabling the joint to
handle shock loads without experiencing
premature failure.
For assistance in ordering your industrial universal joints,
please refer to Curtis’ How to Order instructions
on page 19. To check the static torque rating,
dimensions, weight and other specific characteristics
of Standard Curtis Alloy Steel Joints, please
refer to the Selection Professional guides for single, double
and Turn-Key joints. |

Ball and socket joints and shafts of our production series 0.800 are supported by gliding bearings specifications and therefore can only be used at low speeds.
The permissible maximum speeds depend on the deflection angle and the load, however, they should not exceed 500 min-1.. |

Voith Turbo universal joint shafts transmit torques from a driver to the driven machine safely and reliably.
The range includes standard universal joint shafts as well as custom-made shafts to suit your drives and operating conditions. Voith universal joint shafts are capable of transmitting torques of 0.25 kNm to more than 10,000 kNm.
Our universal joint shafts are available in the following designs:
- Shafts with length compensation (standard or tripode)
- Fixed length shafts
- Joint couplings
- Intermediate shafts with single or double professional bearing
Universal joint shafts are used in
- Rolling mills
- Paper machines
- Rail vehicles
- Marine propulsion
- Pump drives
- Test rigs
- Special drive units |
|
Continuous operation data and conditions, working angle 5°, average life 1000 hours.
The drive shaft is fitted with an "ECS" device for easy coupling with the PTO.
The operations of coupling and uncoupling the transmission shaft and the PTO on industrial tractors or other farm machinery (previously fitted with a dedicated device) are easier and safer with the "ECS" device.
The "ECS" device is made up of a collar fitted on the stub of the yoke, free to rotate around the stub but connected to it through a float-type coupling. |

Depending on the configurations, the Original Elbe Universal Joint Shafts consist of fork parts, joint crosses, industrial needle- or manufacturer of roller bearings, splined length extension and precision tubing.
Fork parts are made using closed die forgings while joint crosses are made from cold professional press or closed die forgings. Highly stressed areas of the universal drive shafts are heat treated to obtain an optimum combination of hardness and toughness. Subsequently, joint cross journals and bearing specifications seats are ground to very fine tolerances.
Each fork part is bored to enable mounting of the needle- or roller bearing housings. Hub splines for length extension are broached and the mating external splines are rolled. If it becomes necessary to reduce the sliding force of the splines, they can be coated with a high quality plastic. |

The complete manufacturing process with all its advantages is identical with the description of the series 0.100.
The manufacturers of bearings of this series feature caster bearing design with all advantages previously described.
The main advantage of this wing-style version is the positive-fit connection resulting from the key of the bearing housing and the key-way of the flange. Therefore the torque is transmitted in a more defined way in comparison to the friction connection.
The four screws used to mount the flange to the universal joint allow fast assembling and disassembling. |

This Double Joint is used for the same application as series 0.400, namely in steering axles of all professional wheel drive vehicles. However, the design of series 0.500 differs slightly from that of series 0.400.
The joint pivots are not located in one plane thus enabling a more compact design. This feature shortens the distance between the centerpiece which results in a shorter installation length.
Series 0.500 offers more joint sizes than series 0.400 thus covering a wider torque range. |

Curtis double joints are available in 14 sizes,
and share all of the advantages of Curtis
single U-joints. Features include:
• Extra angularity allows standard units to
operate at angles up to 70°.
• Quick and easy TakeApart™ design for
easy and economical disassembly and
reassembly, with no special tooling required.
• Firm, positive lockup of the entire assembly
thanks to Curtis’ exclusive Tell-Tale Lock
Ring.
• Built-in lubrication passages with Curtis’
exclusive internal lubrication system.
• Lubrication covers (professional boots) available in
all sizes to retain lubrication and keep out
contaminants, extending the life of the joint.
Curtis Joints do not require grooves on hubs to
retain boots.
• Less galling and seizing because Curtis uses
dissimilar materials on all bearing suppliers surfaces.
• Maximum wear and strength from Curtis’
induction hardened forks.
• Easy machinability due to Curtis’ soft hubs.
• Smooth operations and longer life assured
by close and well-controlled tolerances
between mating parts and Curtis’ built-in
lubrication system.
• Perfect concentricity with hubs ground on
center and centering holes provided on solid
hubs to aid in machining. |

In vehicle construction and mechanical engineering drive flanges form the connection between drive and cardan shaft.
Using modern machine equipment, we manufacture products on the basis of high-quality forgings according to customer drawings.
The drive flanges can be manufactured with internal and external splines as well as with hardened and lead-free ground industrial seal professional bearing surface. |

Cardan joints and cardan shafts according to DIN 808 are supported by sliding suppliers of bearings and their use is consequently restricted to low-speed drives.
The respective permissible maximum speeds depend on the deflection angle and the load, however, they must not exceed 1000 min-1. |

An overrunning clutch transmits rotary motion only in one direction. It is used to eliminate reverse torques generated by the inertia of implements with heavy rotating masses such as rotors or flywheels during deceleration or stopping.
The GE torsionally resilient joint is used on drivelines for different functions depending upon the specific application -The GE can reduce torque peaks generated by the inertia of machines with heavy flywheels or rotors during abrupt starts or deceleration. -The GE can smooth alternating or pulsating loads that may shorten the life of power transmission components. -The GE can modify the natural frequency of a system, to avoid resonance events that could cause failures. - The GE can smooth torsional vibrations generated by unequal working angles on drivelines with more than one joint.

Many applications require corrosionresistant
industrial universal joints to assure
sanitation or to avoid premature
oxidation or deterioration. Curtis stainless
steel U-joints are particularly important, for
example, to industries that use food processing
equipment, and for machinery that comes in
contact with corrosive chemicals or is exposed
to water for long periods. Professional furnace applications
also benefit from stainless steel, which better
withstands high temperatures and other
environmental extremes.
Curtis offers:
• 14 standard O.D. sizes
• 3/8" to 4" diameter
• 303 grade stainless steel in stock
• 304, 316 and other grades available by
special order
For assistance in ordering your universal
joints, please refer to the Curtis How to Order
instructions on page 19. To check the static
torque rating, weight and other characteristics
of Standard Curtis Stainless Steel joints, please
refer to the Selection Guide for single joints
