Conditions in Aircrafts are very extreme and increasingly demanding. ALT BEARINGS is the perfect solution that will help to optimize the space envelope and the weight without compromise on performance and safety. Products are available in stainless steel and with coatings. The customization and design of the interfaces will help to reach the best integration and compactness. The reduced number of parts makes the reliability at the highest level.

In Space applications like spacecrafts (shuttles, rockets) and satellites, the major concern is the contamination of devices and the condensation of outgassing materials in the vacuum of space. As a result, bearings involved in such space environments must be ultraclean with appropriate solvents to avoid any volatile residues which could probably outgas. The HRB is suitable for space applications since it can be cageless thanks to the herringbone threads structure. Also, the HRB can fully be sealed with low outgassing and low-vapor pressure oil/grease or simply coated with PTFE, Vespel or PEEK.

Ball and Roller screw mechanisms are at the core of Linear and Actuation Technologies in mechatronics. These mechanical assemblies combine linear and rotary motions. Many traditional bearing solutions have failed to offer solutions with enough capacities, lifetime, stiffness, or compactness. Complex assembly procedures, bulky housings, specific tools, issues to manage preload have often led to costly downtime and maintenance. Herringbone Roller Bearings, as threaded-based technology, are designed and manufactured to meet the same performance as ball and roller screws. Matching of capacity is reached easily and the bearing becomes a convenient part to assemble on the screw. Linear systems, modules or actuators are then easily and quickly assembled and the space saved helps to reduce costs on surrounding parts.   The HRB will protect the screw by giving a good stability and fixing condition. HRB will be the natural choice on any roller screw and heavy-duty ball screw when “smaller and everlasting” are of primary importance.

In advanced manufacturing industries, the need for Automation and Robotics is continuously growing. This technology increases productivity while reducing costs which contributes to a better efficiency and competitiveness. Specifications in this sector include more demanding requirements for example endurance, speed, precision and protection from contamination. ALT BEARINGS supplies high precision Herringbone Roller Bearings with excellent rotational accuracy, reliability, stiffness and extended lifetime.  They are ideal for automated systems.

Harsh environments and the need to lengthen service life. The Construction Machinery segment operates under extreme conditions such as dust, soil, high loads, tough weather and extreme temperatures. ALT BEARINGS offers special Herringbone Roller Bearings that provide superior performance for these applications and reducing the total cost of ownership to the minimum. In addition, with the use of HRB technology also gives the advantage of a more environmentally friendly operation.

All over the world, Renewable Energy is being developed as a new resource. HRB is designed and manufactured to fulfil the needs of our customers for the clean energy industry. ALT BEARINGS offers solutions for rotating mechanisms suited to the issues imposed by solar panel, wind power generation and power station. Our different bearings solutions are particularly adapted to photovoltaic power generation to save weight, create space, reduce friction, increase design flexibility, and provide excellent running accuracy. For power station, in addition, they ensure heavy duty and reliability.

Pumps and Compressors are widely used in process industries. The challenge in this segment is to maintain long life and reliability and prevent any downtime. In addition, one of the challenges machinery and equipment manufacturers are facing is how to downsize and make their solutions even more compact. Both needs of increased lifetime and downsizing make the HRB the perfect, optimising size and lifetime choice. HRB has been engineered to withstand the most difficult operating conditions: high operating temperatures and vibrations, combined axial and radial loads. The HRB comes also with seals or wipers as options to retain lubricants or to exclude contaminants or even to separate fluids. This superior performance is available also while minimizing friction, wear, heat and noise.

The Medical sector faces challenging applications that require special bearings that can not only combine compactness and reliability but also minimize noise levels and drive torque. In the standard HRB, the main source of negligible noise only originates from contact between rollers ends and carriers. Since carriers can be made of non-metallic materials (plastic, composite) or simply removed, HRB rolls with very much quieter conditions than traditional bearings. In addition, when the environment requires specific materials (for instance non-magnetic or stainless), it is very easy to get a HRB solution whereas conventional bearings only offer a narrow range of solutions. HRBs are a perfect fit to medical applications. Product offering from ALT BEARINGS includes miniature HRBs on request with designs that can be fully customised for special operating conditions.

In the Marine Industry, bearing manufacturers have to respond to new challenging requirements, with increasing environmental and safety and permanent risk of corrosion caused by salt water. Since standard steel bearings will not survive in such critical conditions there can be excessive operational and maintenance costs. Marine HRBs on the other hand are specifically made of specific stainless steel and follow a dedicated process that is designed to provide with the best performance in a harsh environment.

In Toolings, new machine tools require higher speed and stiffness to combine precision and productivity. HRB bearings will easily replace standard bearings solutions with a much higher rigidity and offer options such as seals or wipers. Commonly installed on ball or roller screws, any HRB will give a compact and reliable solution to meet new hard machining or high-speed machining challenges.

HRB is the key bearing to success when failure is not an option. In Military and Defense, ALT BEARINGS provides its expertise, high quality products and services to meet demanding requirements for ground, air and marine equipment.
