SPIETH LOCKNUTS 4 UNIQUE FEATURES - NUMEROUS BENEFITS The locking system enables the application of high clamping forces to ensure that the nut is friction-locked onto the spindle thread. The load is applied to the thread across 3600 sym- metrically and evenly. The locking force and working load act in the same direction and cannot cancel each other out. This is the re- quirement for the highest locking effect while at the same time preserving the connecting The locking procedure is designed to exert a self-centring effect for the nut on the spindle thread. This is the prerequisite for...

Spieth locknuts are precision nuts fitted with an integrated premium thread lock. They are used in all areas of mechanical engi- neering. Precision, safety, rigidity and ease of use are key aspects in the design of a threaded connection. Spieth nuts are the first choice whenever at least one of these aspects is re- APPLICATION EXAMPLES cutting machine tools. automation equipment. • In general drive engineering and • In printing presses and paper-making • In process engineering applications for mixing, crushing and centrifuging. • For metrology, control and test engineering.

FUNCTIONAL PRINCIPLE In this example, based on a type MSF locknut. The principle is illustrated in a simplified dia- gram with enlarged thread flank play. As with every threaded connection, there is a degree of mating play when the nuts are screwed on. As a result, the nut may be aligned with a parallel and/or angled axial offset rela- tive to the spindle axis; in other words, the 2. Spieth locknuts: Self-centring and self- aligning thanks to play restriction Unique: Spieth locknuts are automatically self-centring and eliminate mating play (thread flank play) as far as possible. Thanks to...
