Indexing & Positioning Elements

Elesa have added three new products to their range of ball transfer units (otherwise known as roller tracks or conveyor balls). The UTB units in white acetal-based technopolymer with white polymer or stainless steel roller balls are joined by ESD conductive units and UTR roller transfer units for delicate surfaces.

Ball transfer units aid the movement of flat sheet materials - steel, wood, plastics and similar. They are used for material feed to workstations, movement on transfer lines between workstations or assembly lines, also for moving of components, assemblies and finished packages. They are installed in factories, warehouses, loading areas and receiving stations for onward movement, generally under gravity or manual feed. Normally they are installed with the ball upwards but can also be used inverted as very low-profile castors.

UTB series ball transfer units are suitable for applications on transfer and conveyor lines or end of production lines. They offer linear and rotational movement with maximum cleanliness as they do not require lubrication. The UTB technopolymer ball option lends itself to handling loads with delicate surfaces while the stainless steel ball version is for handling loads with sharp or angular surfaces. Furthermore, since these are corrosion-resistant, it is possible to wash them.

ESD conductive units have an electro-conductive technopolymer body with volume and surface resistivity. The main ball is in stainless steel with internal support and transfer balls also in stainless steel. The mix of these materials prevents the accumulation of electrostatic charges so that UTB-SST-ESD ball transfer units are suitable for applications in "ESD PROTECTED AREA" (EPA) areas.

Elesa UTR roller transfer units facilitate both linear and rotary movement with a soft technopolymer roller. This is suitable for handling loads with delicate surfaces, and may also be washed frequently.

New extended lever toggle clamps from Elesa provide a longer hold bar to hold items in position for working or fixing, allowing them to be secured across larger components. This extended lever allows the clamp arm to reach components in the middle of an assembly while giving clearance to view a template or positioning indices so that operators can work more easily around the clamped component.

These new clamps enable an even hold for welding on control jigs, moulds, templates and work pieces supporting across the whole item which saves time in production and enhances safety, providing a quick, temporary and secure location during secondary operations.

Elesa toggle clamps feature safety release handles in vertical or horizontal configuration for optimum operator convenience to suit the layout of individual work stations. This ensures rapid manual operation which is both fast and accurate, with preset safety (anti-release) lever to prevent accidental opening in the presence of strong vibrations, and to ensure that the operator's fingers cannot be hit by the lever while opening.

Extended lever toggle clamps are available with a flanged (folded) base plate or with a straight (insert) base to suit the orientation required.

A range of polyurethane, rubber or technopolymer wheels from Elesa with 4 different load capacities thanks to the different materials of construction of the metal body. Also available with ball bearings. Suitable for moving trucks and equipment for manual handling (< 4km/h) or mechanical (<16 km/h).
