Belt driven linear actuator is sealed

Sealed belt drive linear actuator is compact and exceptionally clean and incorporates a flush, metal cover strip that runs the entire length of its high strength aluminium beam.

High loads and demanding duty cycles can compromise the operating efficiency and life of many linear motion systems.

These however are the precise operating criteria for which the new SBD Sealed Belt Drive from HepcoMotion has been designed.

This high performing yet cost competitive product provides a compact and exceptionally clean linear solution.

It also introduces a brand new method of sealing that is considered to be far superior to that of alternative products on the market.

Launched at MACH 2006, SBD incorporates a flush, metal cover strip that runs the entire length of the high strength aluminium beam which houses the linear guide and belt.

This prevents the ingress of dirt and debris into the system.

Many of its competitors simply recess the belt into a groove within the body of the system but this method does not provide anywhere near the same calibre of enclosure afforded by SBD.

SBD not only satisfies industry's need for an efficiently sealed system that is immune to its environment but also provides HepcoMotion with a system that is eminently suited to clean-room conditions.

SBD is therefore introduced into two versions, standard for general engineering use and a clean-room alternative that is certified by the Franhofer Institute to confirm its compatibility.

The clean-room version differs only slightly in its sealing method.

It also contains a greater proportion of stainless steel components and has extraction ports in the beam.

This feature enables the customer to add a partial vacuum system to remove any debris from inside the unit before it becomes airborne.

The HepcoMotion SBD is a development of its proven DLS Driven Linear System.

Whilst some degree of cross over is acknowledged, SBD is a much beefier product and therefore targeted at tough applications where long life and minimal maintenance are paramount considerations.

It provides all the characteristics expected from a quality, high-end HepcoMotion linear system.

SBD is available in two beam widths, 80mm and 100mm, and in single beam lengths up to 6m; longer units can be easily constructed by joining.

The mounting carriage plate is removable for customising.

It also incorporates an integral switch cam that can be mounted for left- or right-hand activation.

Units are suitable for high-speed operation, generally up to 4m/s and driven by a polyurethane steel-reinforced tooth belt.

Dependant on the width of the beam, the belt is either 32mm or 50mm wide.

Its tension is factory set but adjustments can easily be made via tensioning screws located externally on the idle end box.

The drive end box is available with either an output shaft or a bored drive pulley for applications that require greater mounting compactness.

The linear guide featured in this new introduction is of a re-circulating type from the HepcoMotion LBG caged and silent range, which combines both higher loads with quiet and smooth movement.

SBD is provided as standard with re-lubrication points and designed for easy motor mounting.

Naturally it is fully compatible with the HepcoMotion MCS Machine Construction System enabling it to be incorporated into any bespoke automation system or machine.
