PRT2 Precision Ring Track expands performance and versatility

PRT2 Precision Ring Track expands performance and versatilityHepcoMotion is launching the PRT2 Precision Ring and Track system, which is the second generation of the company's successful circular and continuous motion system.

The PRT2 system comprises a comprehensive range of ring slides, ring segments, bearings and ancillary components to suit rotary and track system applications. It introduces a substantially expanded range of sizes, with the added benefit of an across-the-range 50 per cent or more increase in load capacity. In addition, stainless steel components are available as standard. This friction-free, debris-tolerant product range also adds several new options that enable designers to create innovative and highly reliable motion systems.

Ring slide are now offered in a much wider range of types (double-edged, single-edged, internal/external Vees, gear cut or plain) in various diameters, and in both steel and stainless steel with hardened Vee edges for wear resistance. They provide circular motion control at the periphery where it is needed and a large hollow centre to accommodate other components, services and even people in the case of an MRI scanner.

Track systems combine ring segments and straight slides to achieve an almost limitless variation of open paths and closed circuits. Both left- and right-hand bends can be negotiated, depending on the carriage selected.

Endless possibilities

In addition to 90-degree and 18-degree ring segments, customers can specify straight slides up to 4m long that can be butted together to achieve track systems of unlimited length. A keyway alignment feature facilitates easy installation and adjustment of joins between straight and curved sides, thereby overcoming any minor inaccuracies in positioning.

HepcoMotion bearings for PRT2 Precision Ring Track systems are available in a range of five popular sizes and various formats in both twin and double-row configurations to suit most design requirements. The special raceway conformity and low radial clearance make these bearings particularly suited to ring slide applications. All are lubricated for life and are available with metal shields to exclude dust and swarf, or nitrile seals to prevent the ingress of liquids and debris. A new addition to the range is the floating bearing whose outer race's axial float accommodates Vee position variation.

In addition to the double-edge Vee ring slides and segments, single-edge versions are also available within the PRT2 programme. Datum faces on both types are provided both internally and externally for ease of location and gear drive options are available with teeth machined into the appropriate register face. The number of teeth is divisible by 4 and 12 in order to provide a wide choice of pinion sizes for exact ratio requirements.


A precision ground ring disc is now available for turntable applications. This provides a large precision mounting surface that can be easily customised to accommodate customers' components.

A carriage clamping brake and also a high moment load carriage system are also new additions. The latter provides extra support and rigidity in applications where high downward or offset loads are anticipated, typically at workstations. Both static and dynamic workstation supports are available.

Customers can also specify bogie carriages with adjustable connecting rods to create a linked carriage system, typically for 'S' bend configurations. They are based on high-performance swivel bearings that are lubricated for life and provide both precision movement and extreme rigidity.

Lubrication on all HepcoMotion products is simple and effective but a new option for the PRT2 Precision Ring Track is bleed lubrication. This continuously doses lubrication directly into the Vee contact faces to eliminate the need for servicing downtime.

The application potential of the PRT2 Precision Ring Track system is extensive and HepcoMotion has therefore designed the PRT2 product catalogue to work in parallel with its website to provide greater scope for detail. This enables readers to download additional data sheets on different features, as well as access more information on the new options in PDF and 2D/3D CAD formats.
