ROBA®-slip hub

Product catalog summary
Introduction
The document details the ROBA®-slip hubs, which are safety clutches designed to protect machinery from overload by allowing the drive element to slip, thus preventing damage.
Specifications
ROBA®-slip hubs come in twelve designs, suitable for various drive units, offering a torque range from 2 to 50,000 Nm, with special designs up to 200,000 Nm. They are compact and made from high-strength materials.
Applications
These hubs are used in machine drives with chain sprockets, toothed wheels, or pulleys, particularly in industries like packaging, transport, construction, textiles, agriculture, and chemical processing.
Design Features
The hubs are fully machined, phosphated, and enclosed to prevent rust and dirt ingress. They are adaptable to different working conditions, with options for high slipping frequency and low torque or low friction work and high torque.
Functional Description
The drive element is clamped between friction linings, with torque adjusted using an adjusting nut and cup springs. Torque adjustment is precise, with options for single, double, or triple cup spring layering.
Product Variants
Variants include the standard ROBA®-slip hub, versions with chain sprockets, rustproof linings, and specialized designs like ROBA®-Co-Pro®, ROBA®-clamp, ROBA®-min, ROBA®-max, and ROBA®-lastic.
Technical Data
Technical data covers sizes 0 to 12, detailing limit torques, operating speeds, and dimensions, along with ordering information and examples.
Conclusion
ROBA®-slip hubs are versatile, reliable safety devices for protecting machinery from overload, offering a range of designs and specifications to meet various industrial needs.

ROBA®-slip hub the load-holding, frictionally-locking safety clutch ROBA® is a trade name which has been the symbol of quality and experience in clutch construction for decades. A comprehensive range of torque limiters has originated from the robust jaw clutch (ROBA®-safety slip clutch). ROBA®-slip hub devices are simple to use. The torque table makes it possible to set the torque according to a scale and offers considerably simplified installation. ROBA®-slip hub devices are reasonably-priced drive elements which protect machinery and equipment against costly damage, and against downtimes resulting...

ROBA®-slip hub-9

your reliable partner ROBA®-slip hub with rustproof friction lining b6 max Used in conjunction with cast iron and steel surfaces, the friction linings can form a rust compound which increases the friction value and therefore the torque considerably. However, a high increase in torque makes the machine unsafe. For this reason, ROBA®-slip hubs can be equipped with disks made of stainless steel, which do not stick to the friction lining and do not form rust compounds. ROBA®-slip hubs with rustproof friction linings offer higher security on drives operating in open air conditions, in particularly...

your reliable partner ROBA®-Co-Pro® is a compact, high-performance safety clutch. On design M (Type 1000), the drive element is clamped spring-pretensioned between two friction linings. The optimised performance capability of the clutch design L (Type 1010) is achieved via a second pair of friction linings. Knobs are provided in the transmission flange for torque transmission onto the drive element. These knobs grip via positive locking into the bores in the drive element (drive element not included in delivery). We reserve the right to make dimensional and constructional alterations. 3) See...

ROBA®-slip hub-11

your reliable partner The frictionally-locking, backlash-free clamping hub is attached to the shaft by tightening one single screw. This means that axial attachment using a shaft collar, adjusting screws or a press cover are unnecessary. ROBA®-clamp devices are used to provide overload protection in machine drives with shaft ends without a keyway. The ROBA®-clamp is used in packing machines, transport machines and devices, construction machinery, textile machinery, agricultural machinery, conveyor systems, feed devices, loading systems, in chemical industry machines as well as in devices and...

ROBA®-slip hub-12

ROBA®-min Types 121 and 123 are slip hubs for drive elements, chain sprockets or toothed wheels with especially small diameters. ROBA®-min devices are used in particular for high transmission ratios or also for double or triple-row chain sprockets or wide toothed wheels. When compared with the L standard Type 100, the ROBA®-min Types 121 and 123 transmit lower torques. An advantage of Types 121 and 123 is that the drive element comes very close to the shaft bearing as a result of the short hub collar.
