At the measured load of 3,5 kN there was no remaining deformation visible on the thrust pad nor was there any breakage.
Threaded stud :
Version ST: black-oxide steel (tensile strength 500 N/mm2).

GN 581

Lifting eye bolts (rotating)

Application and assembly information :
The loads given in brackets refer to the load capacity of the corresponding lifting eye bolt DIN 580. If such a value is not indicated the use of the lifting eye bolts DIN 580 is not permitted!

The bolt-on surface for the lifting eye bolts GN 581 must be plane and at a right angle to the threaded borehole; the countersinking must be the nominal diameter of the thread.

Screwed in, the collar of the screw must make firm contact (do not use washers) and the eye bolt must rotate freely by 360°.

Before applying the load, turn the lifting eye bolt in the direction of the force. The lifting eye bolt is not suitable for frequent rotation cycles under load.

The specified load values apply for a minimum screw-in length of 1 × nominal thread diameter in steel with a minimum tensile strength of 37 kp/mm², at an ambient temperature of 40 °C to + 100 °C. Load-bearing capacity under different conditions upon request.

Operating instructions with more details and specifications are included with every delivery.
Body :
High-tensile forged tempered steel with pink plastic surface coating, 100% electro-magnetic tensile tested to EN 1677.

RLT-U

Roller elements for ELEROLL roller tracks

Features and applications :
– The roller elements, suitably fixed inside the RLT-AL aluminum profiles (Fig. 1) create modular roller tracks for idle handling (both as sliding or containing surfaces), suitable for feeding and discharging benches in construction machinery, storage and picking systems, packaging machinery, etc..
– RLT-U-PA roller elements are also suitable for handling heavy packages, RLT-U-TPU roller elements, with rollers in anti-scratch material, allow the handling of delicate materials such as glass and wood.
– The low friction coefficient between the roller and the roller holder eliminates the need for lubrication maintenance.
– The particular section of RLT-AL profile allows the snap-in assembly of the roller elements into the profile without the need for screws or other fasteners (Fig.1). Therefore the roller elements may be quickly and easily removed and replaced, without disassembling the entire roller track.
– The roller elements are divisible in correspondence of predefined sections (Fig.2) so as to create roller tracks of the precise required length.
Special executions on request :
Rollers in different colour (for example red, yellow, green for the setting up of assembly lines and dynamic warehouses according to Kanban criteria).

RLT-AL

Aluminium profiles for ELEROLL roller tracks

Assembly instructions :
Fix the profile to the supporting structure with screws
of suitable size (Fig. 1) and number for the specific application, by making appropriate holes in the base of the profile.
The profile can be mounted in two points of support (Fig.2) or in complete support (Fig.3).
For the drainage of any fluids that can collect inside the profile (for example in case of applications on machines and equipment whose parts must be frequently cleaned by using water jets, for hygienic reasons) it is recommended to make holes of appropriate size and shape in the base of the profile.
Features and applications :
The profile can hold up to 11 RLT-U roller elements or RLS-U ball elements. The particular section of the profile allows the snap-in assembly of the roller and ball elements without the need for screws or other fasteners.
The profile ensures a high resistance to bending under load, and the assembly of the roller tracks, even in case of not complete support (Fig. 2), without the need for other supports.

Headers for ELEROLL roller tracks

Assembly :
Assemble the headers to the end of RLT-AL aluminum profile by means of two UNI 6954 Ø 2,9 x13 self-tapping screws (included in the supply).

* Trademark application
Features and applications :
RLT-HJ header serves to bind tightly two ELEROLL rollers by engaging them (Fig. 1).
RLT-HE header is the end-element of ELEROLL roller tracks (Fig. 2).
In addition to being an aesthetic element, the headers represent a safety element as they prevent the ends of the aluminum profile from injuring the operator or damaging the handled material.

Wedge clamps

Clamping jaws :
Black-oxide steel.
Features and Applications :
Clamping with the wedge clamps GN 920.1 is achieved via the cylinder screw and the clamp wedge which cause both clamping jaws to move outward.
When loosening the screw, the clamp wedge is returned via an internal return spring which, in turn, loosens the tension.
Wedge clamps are ideal for multiple clamping operations, but they are also suitable for clamping individual workpieces.
The long hole in the clamp wedge serves to compensate tolerances in the workpiece.

Centring bore clamps

Applications :
A circular ball cage containing 3 or 6 balls is forced outwards over an accurately guided cone by means of a screw which, through the exerted thrust, will enlarge the outside diameter of the circular ball cage. This is turn will lead to a firm contact between the Centring clamp and the bore of the workpiece.
Type K (with balls) is used for clamping applications where minute ball marks at the contact points with the workpiece are acceptable.
Type S (with clamping segments) is used in such cases where marks at the clamping points on the workpiece would not be acceptable.

Features :
With Centring bore clamps GN 411.2 workpieces can be centrally positioned and clamped from the inside of the bore.
In addition they offer the following advantages:
Precise self centering
Repetitive accuracy: ±0,025
Accuracy of concentricity: ±0,025
Solid and stable clamping through either 3 or 6 contact points on the workpiece
Clamping of workpieces with uneven or irregular surface (such as castings)
Distortion free clamping
Reduced height
Can be fitted in any position
Large adjustable clamping range

High-strength, straight shackles GN 585 are made in analogy with the US Federal Specification RR-C-271 and feature sixfold safety standards, which means that the minimum failure load is at least six times greater than the value of the nominal load (WLL). The cranked shape is particularly suitable for applications where the shackles are exposed to multiple loads.
The rated size and the nominal load (WLL) are drop-forged into the shackle which makes it easier to select the proper sling gear. In general, the nominal load must not be exceeded.
The designs with nut and split pin (Type B) are normally recommended for permanent connections. The bolts are allowed to rotate, and the nuts are secured against inadvertent loosening with a split pin.
Operating instructions with more details and specifications are included with every delivery.

GN 826

Clamping elements

Adjustable hand levers GN 302-30 :
– Lever body, zinc alloy die-cast, RAL 9005 black matte finish, epoxy resin coating.
– with setting screw AISI 303 Stainless Steel.
Features and applications :
Clamping elements GN 826 are normally used in connection with control knobs and smaller handwheels.
Spindles can so be clamped gently and easily and without much construction and installation effort. The clamping wedge stiffens the spindle, e.g., to prevent maladjustments caused by vibrations or to secure the spindle after adjustment.
This clamping element can also be used to store the spindle.
The clamping element may be mounted such that the clamping lever / the clamping screw is positioned either on the left or the right hand side.
Indicator arrows which can be attached to the circumference of the clamping element are found under GN 711.1.

GN 709.7

Clamping pads

Ball :
Hardened steel (54+2 HRC), Polyacetal (POM) plastic.
Features and applications :
Clampimg pads GN 709.7 are also used in jig and fixture construction, for example for clamping workpieces, as movable bearing surface or as stop. The swivel-mounted ball compensates uneven and non-parallel contact surfaces by as much as 10°. It is also secured against further twisting.
The O-ring holds the ball in position and prevents dirt from penetrating, resulting in a long service life and constant mobility.

GN 706.4

Semi-split set collars

Adjustable handles :
– Lever body, zinc alloy die-cast, RAL 9005 black matte finish, epoxy resin coating.
– with setting screw AISI 303 Stainless Steel.

Features and applications :
Semi-split set collars GN 706.4 can safely and simply be assembled i.e. with high clamping force without damaging the surface of the shaft.
For size d1= 32 and 36, d3 is a through hole; starting from d1= 42 d3 is a threaded blind bore.
These set collars not only serve as an end stop, but they can also be used for fixing or triggering other components such as end limit switches.
