New catalog cardan joints ROTAR
The document highlights 60 years of Italian excellence in manufacturing universal and special cardan joints and shafts by ROTAR®. The company, led by the third generation, focuses on product perfection and quality using certified materials for high performance. ROTAR® is known for product versatility, customization, and superior quality compared to market benchmarks.
Tables provide maximum allowable torque for joints at a 10° inclination angle, with adjustments for angles exceeding 10°. An example illustrates joint selection based on power, speed, and inclination angle.
ROTAR® products require simple maintenance, with greasing frequency detailed in data sheets. Installation guidelines emphasize equal shaft angles, parallel movement, and proper alignment to ensure uniform motion and avoid vibrations.
Standard tolerances are listed, with options for different tolerances upon verification. Special executions include various bore types and set screws. Surface treatments like nickel plating and hardening are available, with special requests handled by the Technical Office.
- AL Series: Carburized and hardened components for durability, suitable for single and double cardan joints and shafts, with a maximum working angle of 45°.
- A Series: Similar to AL Series, offering quick coupling options.
- V/VC Series: Designed for higher mechanical performance with quick coupling.
- X Series: Offers cardan joints and shafts with quick coupling options.
- VX Series: Similar to X Series, with additional customization options.
- VSF Series: Focuses on cardan shafts with specific design features.
Includes splined shafts, hubs, and rubber boots, showcasing a comprehensive product range.
Detailed specifications for cardan shafts and joints, including Series A, V, VC, and X, characterized by specific dimensions, materials, and mechanical properties. Options for grooved and threaded holes are available upon request.
Instructions for calculating shaft lengths using specific formulas. Emphasizes regular lubrication and maintenance for optimal performance and longevity.
Products adhere to DIN standards, using materials like steel (PR80) and stainless steel (AISI 304 and AISI 316) for corrosion resistance.
Regular lubrication is recommended, with specific guidelines for different models. Monthly lubrication for Series V/VC and daily for Series X, unless rubber sleeves are used.
- Series V: High precision with needle bearings for high-speed applications.
- Series VC: Features a commercial forged one-piece cross for the central block.
- Series X: Stainless steel construction for corrosion resistance.
Technical support is available for custom requests and special executions. Stainless steel versions are available for enhanced durability.
Performed upon customer request. Daily lubrication is recommended, or rubber boots filled with grease for protection and self-lubrication.
Detailed specifications for X Series and VX Series cardan joints and shafts, with codes, dimensions, and torque values varying based on application, load, and usage.
Grooved and threaded holes can be machined upon request. Special executions require verification with the Technical Office. Stainless steel versions are available for the VX Series.
Combines stainless steel and needle bearings for high-speed applications with low backlash, offering corrosion resistance, precision, and durability.
Uses sliding spheres for high performance in dusty and high-temperature conditions, designed for durability and reduced wear.
Includes tables with codes, dimensions, and specifications for various series, emphasizing consulting the Technical Office for special requests and feasibility checks.
All models undergo anti-rust surface treatment. Customers are responsible for lubrication, recommended monthly for optimal performance.
Provides detailed specifications for various models, including dimensions and optional features. Quick coupling options are available upon request.
Specifications for different models, including dimensions and material options.
Used in the metalworking sector for transmitting rotary and translational motion, available in steel and stainless steel.
Made from synthetic rubber, these covers protect joints and shafts from dust and are resistant to water and oils.
Designed to fit ROTAR® joints, maintaining lubricant position and preventing debris entry.

Le tabelle riportate indicano le massime coppie consentite (espresse in Nm) rilevate dopo un funzionamento prolungato con angolo di inclinazione di 10°. Se I'angolo di inclinazione supera i 10°, i valor! riportati vengono ridotti secondo i fattori di coppia sotto riportati. The tables give the maximum allowable torque (expressed in Nm) calculated on the basis with an angle of inclination of 10° and continuous use. If the inclination angle is over 10°, the values shown will be reduced in accordance with the torque factor shown below. Esempio; criteri di scelta del giunto adatto secondo la potenza...
