For quick, economical gearbox shaft connections, there is the Smart-Lock system, which combines Ringfeder’s Shrink Disc technology with adaptor bushings. In each Smart-Lock set, the cylindrical bushings mate with the solid shaft’s outside diameter and the hollow shaft’s inside diameter. The Shrink Disc locks all components together — creating a perfect hollow shaft connection every […]

How to install a Ringfeder Smart‑Lock
Ringfeder’s Smart-Lock system combines its proven Shrink Disc technology with a set of adaptor bushings — making gearbox shaft connections a breeze. Before Smart-Lock, solid shaft outside diameters and hollow shaft inside diameters needed to be precision machined to exact dimensional tolerances and finishes. Smart-Lock compensates for clearances up to 0.2 millimeters — eliminating the […]
Ringfeder launches new website and consolidates brands
Ringfeder has announced the launch of its new website, which features the same technologies — but now all under the Ringfeder name. By consolidating its brands—ECOLOC, TSCHAN and GERWAH—the company says it can provide users with a simpler, more streamlined product portfolio, enabling the selection of the power transmission device that best fits your needs. […]
Optimum connection between drive and main spindle
Manufacturers set exceptionally high standards with regard to the quality of the connection between the main spindle and the drive of a machine tool: To ensure perfect operation of the machine, the connection must provide zero backlash and must be easy to establish. Furthermore, it must meet essential damping functions and compensate various types of […]
Safe dimensioning of locking assemblies for extreme loads in applications with belt conveyor pulleys
Ignoring induced forces or the faulty design of belt conveyor pulleys can cause high repair costs. Resulting damage may show itself in shaft breakage, axial movement or plastic deformation of the pulley bottom. Apart from that, downtime losses accrue which can quickly amount to several millions. For instance, the capacity of a large ship loader […]
Ringfeder: Locking assemblies for securing rotors in impact crushers
Apart from transmitting the rotor torque, locking assemblies installed in crushers are subjected to further loads such as bending moments and radial impacts. The factors which have to be considered for these applications are briefly described in this article. Please also watch the video and learn how modern impact crushers work. Function principle Impact crushers […]
What are frictional locking assemblies?
If you want a wear-free way to join shaft components, look no further than locking assemblies. These frictional devices take the place of keyed connections that wear and slip over time. Let’s take a closer look at how locking assemblies work — including their advantages over traditional keyways in high-torque applications. What is a frictional […]

EMO Hannover 2019: The whole world of metal working Things get hard at the EMO Hannover: or more precisely, it is all about metal working. From September 16 to 21, 2019, more than 2,200 exhibitors will showcase their product solutions to about 130,000 professional visitors from all around the world – seizing the opportunity to […]
Ringfeder locking assembly in a ball mill for cement production
Edited by Mike Santora The Challenge After maintenance engineers had examined the ball mill unit thoroughly, the cause of the problem seemed to be the shaft-pinion connection, or to be more exact, the locking assembly that connected the solid shaft with the pinion. Measurements showed the assembly to be out of tolerance by a whopping […]
Hollow shaft connections without precision machining
Creating the perfect hollow shaft connection in gearbox applications isn’t easy. You need to maintain strict dimensional tolerances between the solid and hollow shafts—a process that requires precise, yet costly machining. Ringfeder’s Smart-Lock set overcomes these challenges. It provides a firm, yet flexible connection with clearances up to 0.2 mm. Thanks to its user-friendly, economical […]
