Coupling UCSP

Coupling UCSP

Connect the torque meter without moving the device! New type disk coupling "UCSP"

■Easily separable single disk coupling The structure allows for separation simply by removing a hex bolt with a hole, making it easy to replace UTMIII/UTMII or the measurement target. It enables vertical replacement relative to the shaft, reducing the risk of misalignment. It is ideal for situations where regular calibration of the torque meter is required or where space is limited.

Disk/Spring Coupling RADEX-NC

Disk/Spring Coupling RADEX-NC

Size reduction of the coupling is possible! Achieving cost reduction and space-saving design.

This is a coupling developed for servo motor applications using stainless steel laminas (leaf springs) in an aluminum alloy hub. The leaf spring has high rigidity against torsion and is flexible against bending, allowing for shaft displacement. Due to a specification review in the new 2020 catalog, the allowable torque has increased to 1.5 to 2 times compared to our conventional products. With the larger allowable torque, it is possible to reduce the size of the coupling, achieving cost reduction and space-saving design. It can be widely used in applications such as machine tools and servo drive applications. *For more details, please refer to the PDF materials or feel free to contact us.*

Power transmission × seal Magnetic coupling 'MINEX-S'

Power transmission × seal Magnetic coupling 'MINEX-S'

Ideal for non-contact power transmission using magnets, preventing sealing and contamination of fluids and gases!

The "MINEX-S" is a synchronous rotating type magnetic coupling that transmits torque through the magnetic force generated between the inner rotor and the outer rotor. Since torque is transmitted without contact between parts, there is no wear on the components. Therefore, it is suitable for clean rooms, food machinery, packaging machinery, and other applications where wear particles can be problematic. The drive side and the driven side are separated by a containment shroud (partition), allowing it to be used as a sealing component in pumps and stirrers. Because it does not wear due to contact with rotating parts like mechanical seals or gland packing, it can reduce maintenance time and costs. It also demonstrates high sealing performance when handling hazardous fluids such as strong acids. 【Features】 ■ Synchronous rotating type ■ Can be used as a sealing component in pumps and stirrers ■ Complies with ATEX directives (explosion-proof directives), making it usable in hazardous areas ■ Special designs such as disk types can also be manufactured *For more details, please refer to the PDF document or feel free to contact us.

Disk coupling "RADEX-N, RIGIFLEX-N"

Disk coupling "RADEX-N, RIGIFLEX-N"

Many achievements in the pump and wind power generation industries! Disc coupling

RADEX-N and RIGIFLEX-N are maintenance-free steel laminar couplings. The high-strength stainless steel laminates possess extremely high rigidity against torsion while absorbing displacements that occur between the mounting shafts without generating significant axial reaction forces. RIGIFLEX-N can be used in temperature environments up to 280°C since all components are made of steel. We can offer a wide range of options for intermediate shaft (spacer) lengths and methods of fastening to the shafts (set screws, clamping types, wedge fastening, etc.). Additionally, we can accommodate requests for installation not only in the horizontal position but also in the vertical direction. We also have a lineup of products that comply with API610 and 671 standards. Furthermore, our Q&A materials (leaflets) provide detailed explanations with illustrations for frequently asked questions from customers, so please be sure to check them along with the catalog!

Coupling lineup for engine machines in construction, agricultural, and road machinery.

Coupling lineup for engine machines in construction, agricultural, and road machinery.

Rich market experience! Couplings for engines

The engine generates torsional vibrations due to explosions, and if the torsional vibration frequency matches the natural frequency of the drive shaft system, including the coupling, there is a risk of damage to the drive components due to resonance. At KTR, we use a torsional vibration analysis program to propose couplings suitable for your company. KTR's couplings for engines have been adopted by domestic and international manufacturers in construction machinery, road machinery, agricultural machinery, compressors, etc., with a global shipment of over 200,000 units annually.

Flexible Coupling EVOLASTIC

Flexible Coupling EVOLASTIC

Compact in the axial direction and available in a variety of designs, a flexible coupling widely suitable for motor and engine drive applications.

EVOLASTIC is a highly flexible, backlash-free flexible coupling that allows for the connection of shafts and flanges. The preloaded elastomer absorbs torsional vibrations and shock loads in the drive system. It also efficiently dampens solid-borne sound while simultaneously absorbing misalignments (axial displacement, parallel displacement, angular displacement) that occur between the driving and driven machines. The elastomer, an important component, is shaped into a ring by vulcanizing and bonding rubber and metal. The permissible temperature for natural rubber types (WN, SN, MN) is up to 90°C, while for EPDM types (WE, SE, ME) it is up to 110°C. It is possible to select different rubber hardnesses without changing the size of the coupling. The basic design is broadly categorized into bolt-connected types and plug-in types. Hubs and hubs, or hubs and flanges, can be combined according to the mounting dimensions of the driving and driven machines. This allows for flexible responses to various mounting dimension requirements. *For more details, please download the PDF or feel free to contact us.*
