•
Before installing or handling this product, read instruc-ons carefully and completely. Due to possible danger to
persons or machinery resul-ng from improper use of this product, it is very important to follow correct
procedures. Proper installa-on, maintenance and opera-on procedures must be observed. All instruc-ons
included in this manual must be followed carefully. Handling, installa-on and removal of this product must be
done by skilled personnel, familiar with the product, the applica-on and all hazards involved.
•
Suitable safety devices should be provided and applicable safety rules should be observed as specified in safety
codes. Those are neither the responsibility of MAV S.p.A., nor are provided by MAV S.p.A.
•
Contraven-on of install and safety instruc-ons will void all claims under warranty.
•
During storage or handling opera-ons, use only tested and approved handling and/or li7ing tools. Make always
sure that components of Locking Assembly are secured against slipping, falling or rolling.
•
Prior to ini-a-ng installa-on or removal procedures, check to ensure that no loads are ac-ng on Locking
Assembly, sha7 or any connected component. Motor and drive train must be switched off and secured against
accidental ac-va-on.
•
Locking Assemblies MAV 1062 and MAV 6901 provide a rigid, zero-backlash, fric$onal keyless connec$on between a
sha( and hubs such as gears, pulleys, cams, levers, rotors and many others.
They are suited for transmi+ng torque, axial load, bending moment and radial load, separately or in combina$on.
Applied loads are transmi.ed via pressure and fric$on across the fi+ng surfaces between Locking Assembly, sha(
and hub bore.
In $ghtened condi$on, Locking Assemblies exert high radial pressure on sha( and in hub bore.
•
Locking Assemblies are supplied ready for installa$on and are composed of (fig. 1):
◦
one inner ring (slo.ed), with integrated push-off threaded holes
◦
one outer ring (slo.ed)
◦
one set of socket head cap screws ISO 4762 grade 12.9
•
Lubrica$on. Func$onal values are rated with screws, locking rings, sha7 and hub contact areas coated with a film of
mineral or synthe-c-base oil with low content of addi$ves (specific corrosion-protec$on purpose products as well as
products used to release oxidized connec$ons are not recommended). DON'T USE low fric-on lubricants based on
molybdenum disulphide, graphite, copper and other similar compounds (e.g., Molykote®, Never-Seeze® or similar
products).
•
Recommended sha( / hub bore tolerances: h8 / H8.
•
Recommended sha( / hub bore surface finish: 0.8 ≤ Ra ≤ 3.2 µm

- Page 1 GENERAL INFORMATION • Locking Assemblies MAV 1062 and MAV 6901 provide a rigid, zero-backlash, fric$onal keyless connec$on between a sha( and hubs such as gears, pulleys, cams, levers, rotors and many others. They are suited for transmi+ng torque, axial load, bending moment and radial load, separately or in combina$on.
- Page 2 Fig. 1. Composi$on. • Tightening torque. Func$onal values in the catalog are based on specified $ghtening torque (Ma). Tightening torque may be reduced up to 0.8*Ma (max reduc$on by 20%). A given reduc$on of $ghtening torque leads to a propor$onal reduc$on of func$onal values. •...
- Page 3 Inner and outer rings shall be completely supported by sha7 respec-vely hub bore (fig. 2). MAV 1062 shall be COMPLETELY (whole length) mounted inside of the hub bore (fig. 2), to avoid bending of inner ring’s flange. At this point, relocate the screws used to disengage the locking rings.
- Page 4 4. Tighten the screws by hand in a crosswise pa.ern, star$ng with a screw located at 90° approx. respect to slit (fig. 3), un$l fi+ng clearances with sha( and hub bore are bridged and connected components are slightly locked, while making sure that hub is aligned as required using a dial indicator.
- Page 5 REMOVAL SAFETY NOTICE Prior to ini-a-ng the removal procedure, check to ensure that no loads are ac-ng on Locking Assembly, sha7 or any connected component. Motor and drive train must be switched off and secured against accidental ac-va-on. Some locking screws will be used for removal. The user shall make sure that the end -p of these screws is ground flat and chamfered, in order to prevent damage to the threads and allow their removal from push-off...
