Locking and braking elements
GENERAL INTRODUCTION
The vast world of linear technology includes locking and braking elements for linear guideways playing a key role in positioning, stop and braking phases in several industrial applications. On one hand, these components guarantee efficient production because of their high and long performance resulting from high precise positioning, high clamping forces, zero relative motion and high rigidity. On the other hand, locking and braking elements ensure maximum safety due to safe clamping and emergency stop.
Locking and braking elements can meet any need. They are high quality and easy to install components which can be manually, pneumatically, hydraulically or electrically controlled.
MANUAL UNITS
They are simple and reliable manually controlled locking elements. Opening and closing locking is carried out by rotating and adjusting a lever or screw without using auxiliary tools. Clamping jaws provide floating support ensuring a symmetrical distribution of forces. In other words, it prevents transverse forces taking over in the surrounding structure during locking process.
PNEUMATIC UNITS
Pneumatic locking elements works with a mechanical clamping by activating a pneumatic cylinder with compressed air which moves a wedge gear to transmit power between piston and clamping and braking jaws. This pressure clamping process requires an excellent compressed air supply. For this reason, the use of clean and lubricated air is needed to ensure a safe functioning.
HYDRAULIC UNITS
Hydraulic locking elements are pre-filled with oil and hydraulic connection is mounted on both sides. At the time of installation, one connection for supply is enough. It’s worth remembering that special attention is required to the ventilation of fixed and flexible hydraulic lines during start-up. Indeed, the ingress of air can damage sealing elements and compromise clamping process.
ELECTRICAL UNITS
Electrical locking elements use electrical transmission to produce necessary clamping forces. Indeed, both in opening and closing phase, the system is powered by a 24V DC voltage which ensures an excellent energy efficiency and moves a wedge gear lengthways by transmitting the force between electric motor and clamping jaws.
