HepcoMotion is enhancing its GV3 range with the introduction of new components

HepcoMotion is committed to providing customers with an unrivalled choice of products, sizes and options to cater for virtually any linear motion requirement. In testament to this, HepcoMotion is adding to its flagship GV3 range with the introduction of a number of new components that offer real benefits to design engineers. Two of these new components, the new side access adjustment carriage feature, and twin taper roller bearings, are likely to be particularly well received by engineers looking to reduce maintenance time and extend service life.

Side Access Adjustment Saves Valuable Maintenance Time

The addition of the new side-access adjustment (SAA) carriage to the GV3 range of products is likely to be a popular choice for applications where components are mounted to the carriage plate, or access is restricted. The SAA reduces downtime as there is no need to remove mounted fixtures from the carriage plate when adjusting the bearings. This is particularly advantageous if the customer has complex components mounted to the carriage plate that would be time-consuming to remove and then re-attach.  Engineers can simply adjust the bearings with the fixtures in place to remove any wear or play, to return the system to its original running condition.

SAA carriages are very convenient for maintenance as there is no need to run the carriages off the end of the slide to remove – it can be done anywhere along the slide.  This saves having to dismantle part of the machine in cases where the ends of the slide are blocked for example.

Engineers will find the SAA carriages very easy to set.  Adjustment is made via two screws located in the side of the carriage plate.

Twin Taper Roller Bearings For Extended Life

A further addition to the GV3 range is the new twin taper roller bearing. Ideally suited to applications requiring higher load capacities, it is physically the same size as the standard Ø 54 bearing, yet offers 10 x the life.  The twin taper roller bearing also offers increased rigidity – a key requirement for many applications where precision needs to be high.  Twin taper roller bearings are greased for life internally, with nitrile seals providing a high degree of sealing against ingress of water or debris.  Twin taper roller bearings are only available in combination with SAA carriages but specials can be supplied to suit other carriage plates. In these cases there will be a slight increase in system height.

Catering for a wider portfolio of applications, the new twin taper roller bearings join Hepco’s current range of bearings comprising of standard, slimline, vacuum and extreme temperature, and floating bearings.

Hepco’s floating bearings are proving to be a popular solution for when two systems are mounted in parallel as they ‘float’ by up to +/- 1.25mm in the axial direction, allowing misalignment to be overcome and avoiding binding of the linear system. Set-up times are greatly reduced as floating bearings overcome the need to accurately set opposing slides perfectly in parallel.

New Catalogue

In line with the new GV3 components, Hepco is pleased to launch a new colour GV3 product catalogue and an accompanying technical guide providing more in-depth, technical detail and additional components.  Hepco has also produced a series of six animations, highlighting the major benefits of V Guide technology against ballrail systems. These can be accessed from the new GV3 online catalogue, also elsewhere on the Hepco website and on Hepco’s YouTube channel.

The new catalogue has been created to provide users with the information needed as quickly and efficiently as possible. When accessing online, interactive hyperlinks take users directly to the information they require – such as the product pages, technical guide, CAD files or product animations for example.  Designed with engineers in mind, the new catalogue is inherently user friendly yet packed with an array of comprehensive information.

In addition to the side access adjustment and twin taper roller bearings, the new catalogue also features a host of additional products including vacuum bearings, floating bearings, bleed lubrication, end stops and shock absorbers, plus connectivity to Hepco’s range of aluminium profiles. The new GV3 catalogue can be found at


GV3 is one of over forty-two major product lines offered by HepcoMotion, which include thousands of individual components in various sizes. The product range has been designed to cater for almost any linear, and many rotary requirements.  HepcoMotion has been leading the development of V Guide technology since 1969, and continues to develop innovative linear products that offer new solutions to design engineers.
