Ruland BC32-12-10-A 2024 or 7075 Aluminum Hubs Bellows Coupling, Clamp Style, 0.750" x 0.625" Bores, 2.000" OD

Model: BC32-12-10-A   |    Mpn: BC32-12-10-A   |    Ean: 0634529062920   |    PartNumber: BC32-12-10-A   |   Asin: B016APOVK8

Ruland bellows couplings are zero-backlash, torsionally stiff, and have a balanced design. They are made from black anodized aluminum hubs and stainless steel bellows to offer superior performance in precision servo applications. The stainless steel bellows are ideal for transmitting torque due to their thin walls allowing the coupling to easily flex while remaining rigid under torsional loads. Bellows couplings can accommodate all forms of misalignment angular, parallel, and axial motion.

Combining aluminum hubs with stainless steel bellows results in a lightweight, low inertia coupling that is well suited for precision applications found in a variety of industries including semiconductor, solar, printing, packaging, and machine tools. Bellows couplings have no moving parts ensuring a long maintenance-free life. Ruland uses a balanced design to reduce vibration in high RPM applications of up to 10,000 PRM.

Ruland bellows couplings are carefully made from select bar stock sourced exclusively from North American mills and are machined to a fine burr-free finish. Hardware tests beyond DIN 912 12.9 standards for maximum torqueing capabilities. Ruland, founded in 1937, manufactures all products in our Marlborough, MA USA factory under strict controls using proprietary processes. Bellows couplings are RoHS2 and REACH compliant.

Features

  • Zero-backlash with high torsional stiffness for excellent accuracy and repeatability
  • Balanced design reduces vibration at high speeds
  • Thin walls of the bellows allow the coupling to flex easily yet remain rigid under torsional loads
  • Hardware exceeds DIN 912 12.9 standards for maximum torque capabilities

Huco 321.17.3131.Z Size 17 Flex-Ni Bellows Coupling, Electroplated Nickel With Aluminum Hubs, Inch, 0.375" Bore A, 0.375" Bore B, 0.67" OD, 1.06" Length, 1168.2 in-lbs Max Torque

Model: 321.17.3131.Z   |    Mpn: 321.17.3131.Z   |    PartNumber: 321.17.3131.Z   |   Asin: B004HW6ZBA

This Huco Flex-Ni electroplated nickel bellows coupling with aluminum hubs is all metal, has a torsionally rigid design, and its single-piece construction gives it increased service life over couplings with moving parts. The aluminum alloy hubs are treated with a clear anodized finish for resistance to corrosion, and the coupling's flexible bellows are electroplated nickel for strength, durability, and corrosion resistance. The fasteners are made of alloy steel for strength and durability. This bellows coupling can operate in temperatures ranging from -58 to 248 degrees F (-50 to 120 degrees C) and is commonly used in applications that require high torsional stiffness and torsional integrity. The coupling is suitable for use with encoder drives, closed loop servo systems, pulse generators, and metering valves, among others.

Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other. Most flexible couplings consist of two hubs and a middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the two shafts. Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from one shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from one type of misalignment to another. Flexible couplings are used in a broad range of applications, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.

Huco Dynatork manufactures couplings, piston air motors, brakes, clutches, gear boxes and other transmission products. The company, founded in 1965, meets the quality assurance standards of the British Standards Institution (BSI), the International Organization for Standardization (ISO) and the Deutsches Institut f r Normung (DIN), and is based in Hertfordshire, England.

Features

  • Bellows coupling for use in instrumentation, medical equipment, sensitive high precision drives, and other high precision positioning applications requiring high torsional stiffness and torsional integrity
  • Aluminum alloy hubs with clear anodized finish for corrosion resistance
  • Nickel-electroplated bellows for corrosion resistance
  • Single piece coupling for increased service life over couplings with moving parts
  • Operating temperatures range from -58 to 248 degrees F (-50 to 120 degrees C)

Notes
Note 1: Performance ratings are for guidance only. The user must determine suitability for a particular application.
Note 2: Torque ratings for the couplings are based on the physical limitations/failure point of the metal bellows.
Under normal/typical conditions the hubs are capable of holding up to the rated torque of the metal bellows.
In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the metal bellows.

Double Loop Couplings with Steel HubsThe double loop coupling uses a moulded plastic element permanently swaged to steel or stainless steel hubs to give a compact design. It forms an effective two-stage coupling with exceptional flexibility in all three modes. Ideal for transmitting rotation in small drives, this type of coupling works without any friction, wear or noise, although its low torsional stiffness makes it less suitable for high precision positioning applications.
