Standard feedersBespoke, customer-specific solutions
Suitable for Industrial, Pharmaceuticals, Medicals
Our unique patented multi magnet drive units ensure smooth consistent feed characteristics with minimal vibration to the assembly machine. All drive units and associated control boxes are CE marked and supplied UL/CSA approved for the American market where necessary.
RNA bowls can be made of a range of materials, including stainless steel, aluminium, polyamide, with different coatings (polyurethane, habasit, brush, flock, metaline and so on), selected to suit the application.
Sizes range from 69mm diameter to 1200mm diameter, RNA represent a complete range of vibratory bowl feeders available from stock, including drive units, bowls, bowl centres, control boxes and additional accessories (stands, base plates, sound covers and sensors). Special requirements are available upon request.
We manufacture tooling to orientate components, which together with our standard equipment, provides a system ready to integrate with a customer’s further process machinery, packaging and assembly lines.

Vibratory bowl feeders are the most common part feeding devices used to feed components in Industrial Assembly Automation Applications. Vibratory feeders are self-contained systems, comprising of a specially tooled bowl feeder that orients the components, a vibrating drive unit m upon which the bowl feeder is mounted and a variable-amplitude control box.
How does a bowl feeder work?
The bowl feeder, including an out feed accumulation track to convey parts along and discharge into the assembly machine are supplied in many shapes and sizes. The drive unit, available in both electromagnetic and pneumatic drives, vibrates the bowl feeder, forcing the parts to move up a circular, inclined track. The track is designed to sort and orient the parts in consistent, repeatable positions. The track length, width, and depth are carefully chosen to suit the application and component shape and size. Special track coatings are applied according to shape size and material of the parts which aids traction, damage to the product and lower acoustic levels. A variable speed control box is used for controlling the vibration of the bowl feeder and stops the flow of parts to the out feed track via sensors.
Applications of bowl feeders
Vibratory feeders are utilized in many industries including pharmaceutical, automotive, electronic, food, Fast Moving Consumable Goods (FMCG), packaging and metal working industries. It also serves other industries such as glass, foundry, steel, construction, recycling, pulp and paper, and plastics.
Vibratory feeders offer a cost-effective alternative to manual labour, saving manufacturer’s time and labour costs. Several factors must be considered when selecting a parts feeder, including the industry, application, material properties, and product volume.
RNA engineer and manufacture the most reliable and highest quality vibratory part feeding systems providing low maintenance and accurate handling solutions for a wide range of material parts processing applications.
Our experienced project managers will be responsible for the entire production process of your application. If you are looking for a high quality vibratory feeder or other special purpose handling system, please do not hesitate to contact us either by phone, email or simply using the enquiry form.

RNA drive units offer reliability and endurance. The use of high performance magnets give a continuous high feed rate regardless of the number of parts in the bowl.
RNA provide state of the art controllers for all vibratory drive units. All controllers are CE approved and also available with CSA/UL certification.
Bowl Coatings
Bowl coatings minimise the wear and tear of the bowl, treat the parts more carefully and reduce the running noises. The coating material can be chosen according to the application and parts.
Base Plates
The base plate enables easy mounting of the drive unit to the machine table. The base plate SRG hat integrated fixing devices for the mounting of control units.
Stands and Top Plates
RNA stands and top plates have a large height-regulating range. Due to their finely adjustable regulation, they enable an optimal interface compensation at the part discharge points.
Sound Covers
Reduce noise and protect against dust
