Your projects are our drive Know-how: Over 90 years of expertise. Rely on decades of engineering expertise from the inventor of the friction spring. As an expert in drive and damping technology, we are your reliable partner wherever forces are at work. Be it the permanent transfer of very high torques due to non-positive or positive connections or the absorption and trapping of extreme energies to protect expensive constructions. Your expert partner: From development to the finished product. We accompany you through to the successful completion of your project. Beginning with the...

RINGFEDER® Locking Assemblies Introduction Keyless shaft-hub locking devices have been the cornerstone of the RINGFEDER®. For over 90 years, our product offering of internal clamping and external clamping locking devices and global support has been unparalleled in the industry. Locking Assemblies self-centering Self-centring RINGFEDER® Locking Assemblies enable extremely precise concentricity in the clamped components. The maximum concentricity error for the clamping sets that are machined in a clamping process is an extremely low 0.04 mm. These clamping sets are used primarily in gear...

RINGFEDER® Locking Assemblies Transmissible torques T [Nm] with low surface pressure without axial displacement with low surface pressure without axial displacement RINGFEDER® Locking Assemblies stainless steel Transmissible torques T [Nm] Locking Assembly selection on www.ringfeder.com Our website offers you a selection tool that will help you to determine which locking assembly is suitable for you. Following selection criteria are available: transmissible torque at given TA or shaft diameter Additional filter criteria: axial displacement (with or without) self-centering (yes or no)...

Locking Assemblies RINGFEDER® RINGFEDER® locking assemblies are characterised by the absolute freedom of movement and high fatigue properties of the components. The fast, simple assembly is achieved through the use of few screws. The angle of alignment between the shaft and the hub is thus exact in every position. No adjustment work is necessary. Simple dismantling is carried out using extraction threads – no additional aids are necessary. The RfN 7012.2 series is even self-releasing.

Locking Assemblies RINGFEDER® RfN 7003 self-centering without axial displacement Further information on RINGFEDER® RfN 7003 on www.ringfeder.com with low surface pressure Two piece design with slit and single taper and without flange Self-centering, 2-piece Locking Assemblies, which can be used - due to the slit - also at larger tolerances. The hub slightly positions during mounting towards the screw head. For dis ssembly only few release a screws are required. Through the stiffer geometry of the flange, the deformation of the flange is significantly lower than with standard products....

Locking Assemblies RINGFEDER® RfN 7004 self-centering without axial displacement Further information on RINGFEDER® RfN 7004 on www.ringfeder.com with low surface pressure Extended version of the RfN 7003 Is the extended design of series RfN 7003. Here, due to the low pressure the hub can be designed very cost-effective (small outer diameter). Excellent concentricity and very easy to dismantle – these self-centering Locking Assemblies provide particularly good concentricity between the clamped parts. During mounting, minor axial displacement towards of the screw head. The flange is...

Locking Assemblies RINGFEDER® RfN 7005 self-centering without axial displacement Further information on RINGFEDER® RfN 7005 on www.ringfeder.com with low surface pressure Three piece self-centering design for heavy duty torques 3-piece, self-centering, slitted Locking Assemblies for highest torques. During assembly a minor axial displacement of the hub occurs. The front and rear thrust rings are separately released through release threads. Characteristics Excellent concentricity – because of the long, flat cone Special features – low axial displacement and highest torque transfer

Locking Assemblies RINGFEDER® RfN 7006 self-centering without axial displacement Further information on RINGFEDER® RfN 7006 on www.ringfeder.com with low surface pressure Two piece design with single taper Has all positive features of series RfN 7003. However, through the bigger flange diameter an axial displacement of the hub during mounting is averted. Is also applied with belt pulleys. Excellent concentricity and very easy to dismantle – these self-centering Locking Assemblies provide particularly good concentricity between the clamped parts. During mounting, minor axial displacement...

Locking Assemblies RINGFEDER® RfN 7007 self-centering without axial displacement Further information on RINGFEDER® RfN 7007 on www.ringfeder.com with low surface pressure Two piece design similar to RfN 7004 Is a modification of RfN 7004 with all its positive features, but here same as RfN 7006 - the axial displacement during mounting is averted. Excellent concentricity and very easy to dismantle – these self-centering Locking Assemblies provide particularly good concentricity between the clamped parts. The flange is reinforced at the critical point. This prevents a bending and lifting of...
