ETP ETP-MINI R-8
Mini R Size 8 17Nm 8mm
Bore Coupling
ETP-MINI is available as standard for shafts 6 -14 mm, also imperial. Runout ≤ 0,02 mm. Number of mountings 100 (type R: 50). ETP-MINI is one of the most compact mechanical hub-shaft connections on the market, allowing you to optimise your design.
Construction
ETP-MINI is a mechanical connection which consists of two, partly slotted, conical steel sleeves (type R stainless) and cap head clamping screws (type R stainless).
Operation
By tightening the screws, the inner sleeve is pressed against the shaft and the outer sleeve against the hub, thus forming a rigid joint. When dismantling one, or if necessary, two of the screws are moved to the threaded dismantling holes in the flange. By tightening, the sleeves will separate and the joint will easily loosen. ETP-MINI type R has one screw more than ETP-MINI in order to transmit the same torque (lower
tightening torque for stainless screws). The inner sleeve of ETP-MINI has a light recess close to the flange in order to create a more uniform surface pressure to the shaft.
ETP-MINI R, suitable for the food industry.
