Support Rollers
AMIGO support rollers, designed in a yoke-type configuration, are engineered to operate on various track types and are ideal for applications such as cam drives and conveyor systems. These rollers utilize needle or cylindrical roller bearings and are supplied by SKF as ready-to-mount solutions.
- Robust design to handle high radial and axial loads for reliable performance
- Thick-walled outer ring for enhanced durability and shock absorption
- Available with crowned or cylindrical (flat) running surfaces for versatile applications
- Pre-lubricated for life, reducing the need for regular maintenance
- Capped with seals or shields to provide effective protection against contaminants
- Enhanced corrosion resistance options for demanding environments
Support rollers are critical components in machinery and equipment requiring stable, guided motion under heavy loads. Their durability and ability to handle both radial and axial forces make them suitable for a wide range of industrial applications. Examples of applications include:
- Conveyor and material handling systems in logistics and manufacturing
- Guide systems in steel mills and paper production plants
- Construction and mining equipment for heavy-duty operations
- Agricultural machinery for guided movement and load distribution
- Automated production lines and robotics
- Linear guidance systems in large machinery
- Sliding doors and heavy-duty rail systems
Support Rollers - Designs and Variants
Support Rollers Without Flange Rings
Support rollers without flange rings are specialized bearings designed to require adjacent components to guide the outer ring and cage axially. They are based on needle roller bearings and are known for their high load-carrying capacity and compact design.
Support Rollers with Flange Rings
Support rollers with flange rings are designed to be non-separable units that do not require adjacent components to guide the outer ring and cage axially. These rollers are equipped with various flange designs, such as pressed-on flange rings (NATR and NATV designs) or loose flange rings (NUTR, PWTR, and NNTR designs). They provide stable axial guidance and accommodate axial loads that can occur due to skew or tilting.

Frequently Asked Questions (FAQs)
Q: What are support rollers?
A: Support rollers are specialized bearings designed to provide stable guidance and support for heavy loads in applications that require both radial and axial load-bearing capabilities. They are often used in conveyor systems, cam drives, and other track-guided machinery.
Q: What is the difference between support rollers with and without flange rings?
A: Support rollers with flange rings have integrated or loose flange rings that guide the outer ring axially, providing stability and preventing misalignment. Support rollers without flange rings rely on adjacent components to provide axial guidance, making them more compact but requiring precise installation.
Q:Where are support rollers commonly used?
A: Support rollers are widely used in automotive manufacturing, material handling, construction, steel mills, and packaging equipment industries. They are also found in linear guidance systems, rail systems, and heavy-duty door and sliding mechanisms.
Q: How do I choose the right support roller for my application?
A: Consider factors like load capacity, operating environment, speed, temperature, and axial guidance needs. Additionally, depending on your application’s alignment requirements, choose between rollers with or without flange rings.
Q: What are the main benefits of using support rollers?
A: Support rollers offer high load-carrying capacity, durability, and stability under varying conditions. They are designed to handle radial and axial loads, provide effective seal against contaminants, and ensure smooth guided motion.
Q: What types of support rollers are available?
A: Common types include NATR, NATV, NUTR, PWTR, and NNTR designs. Each type offers different features, such as various flange designs, sealing options, and load-bearing capabilities, to suit specific applications.
Q: Do support rollers require regular maintenance?
A: Most support rollers are pre-lubricated for life and require minimal maintenance under normal operating conditions. However, if the rollers are exposed to contaminants, moisture, or high temperatures, periodic inspection and relubrication may be necessary.
Q: Can support rollers handle high temperatures?
A: Yes, certain types of support rollers are designed to operate in high-temperature environments. However, it’s essential to choose the right type and materials based on your application’s specific temperature range and operating conditions.
Q: What materials are support rollers made of?
A: Support rollers are typically made from high-grade steel for strength and durability. Some designs may include corrosion-resistant materials, reinforced seals, or special coatings to handle challenging environments.
