WHO WE ARE We are an Italian company with over 65 years of experience in the design and in-house production of mechanical components for power transmission. Founded by Mario Piazzalunga in 1960, we have grown thanks to constant innovation and a passion for quality.

We have always believed that collaborating and sharing is the best way to grow professionally. “Why do I have to buy expensive pieces if I can build them by myself?” Mario Piazzalunga must have asked himself this question, looking for the umpteenth time at the pulley used on his equipments. IT ALL BEGINS WITH THE FAULTS THAT MARIO HAS TO REPAIR The rest can be briefly summarized : in 1971 we moved production from Bergamo to the current location in Bracca. At the end of the 80s, his sons Marco and Mauro joined the company and the are still running it today. Around the same time, we began producing...

• Transmission couplings • Torque limiters • Variable speed pulleys Motor bases

Power Transmission Couplings Transmission couplings are devices designed to connect two coaxial shafts. In addition to the precise transfer of torque, the main purpose of couplings is to compensate for the misalignment between the motor bases and the user side. GSTR SERIES Elastic couplings - 4,5 - 9.000 Nm GD SERIES Curved tooth gear couplings - 600 - 90.000 Nm GD.P SERIES Curved tooth gear couplings with resin crown - 11,5 - 840 Nm GD.S SERIES Curved tooth gear couplings with integrated crown- 600 28.500 Nm

Torque Limiters Torque limiters (or safety couplings) are indispensable mechanical components which are installed along the driveline where effective protection of mechanical parts is required. LF SERIES Friction plate limiters - 2 - 23.000 Nm LSE SERIES Compact balls torque limiters - 7,5 1.450 Nm LS-LR SERIES Balls/rollers torque limiters - 2,5 - 12.000 Nm LSG SERIES Precision safety torque limiters- 2 - 750 Nm

100 SERIES Variable speed pulleys are the transmission elements that allow the roration speed of transmission shafts to be adjusted easily, quickly, continuously and at relatively low costs. ES/RV SERIES Variation ratio 1:9 - 0.25 - 18.5 Kw MINI SERIES Variation ratio 1:6 - 0.25 - 0.75 Kw BES SERIES Variation ratio 1:9 - 0.37 - 30 Kw TXR SERIES Variation ratio 1:9 - 18.5 - 55 Kw GVBE SERIES Variation ratio 1:9 - 0.37 - 110 Kw

Slide Motorbases SS SERIES The motor-bases rallow wheelbase variation for transmissions using variable double-expansion pulleys. They are also designed and used for belt tensioning in power transmissions with standard pulleys (trapezoidal and/or toothed). The compact design and slotted fixing holes allow for easy mounting and an equally easy alignment system. SL SERIES Motor size: 71 - 132 SMP SERIES Motor size: 56 - 132 SC RAILS SERIES Motor size: 63 - 355 SB RAILS SERIES Cast iron - Motor size: 90÷315 SA RAILS SERIES Motor size: 71 - 350

Piazzalunga is not just a supplier: it is a strategic partner. We offer: VALUE PROPOSITION CUSTOM DESIGN FLEXIBLE PRODUCTION EVEN IN SMALL SERIES FAST DELIVERY RELIABILITY, DURABILITY Each product is designed to adapt to the specific needs of the customer, improving the performance of their machines and reducing maintenance costs.

CONSTANT EXPANSION We strongly believe that cooperation and sharing is the best way for a professional growth. That’s why we cooperate with the University of Bergamo: mechanical and management engineering. The constant contamination of skills and experiences help us to innovate products and processes.

Every single piece is the result of a thorough in-house design and production process which goes from the choice of materials, to experimentation and testing procedures throughout the production cycle. This allows us to offer the best solution for the design and maintenance of your machine.

CUSTOM PRODUCTS Choose our flexibility: Innovation Speed: from concept to prototyping Small runs: we optimize costs and production times. Variants on basic models: internal design for fast and efficient customizations. Production: CNC department (turning, milling), broaching and grinding, with cutting-edge software and equipment. Involve us in your projects and test our ability to create customized, efficient and profitable solutions!

YOUR VALUE IS OUR GOAL We know that your value depends on the quality of our products. We start from this awareness, from communication and mutual knoweledge in order to build a relationship based on trust. It is not enough for us to provide you with good products: we want to help you reach your goals That’s why we we start where others give up “Successful companies turn their customers into winners as well. The shrewdest companies are constantly creating new value for customers, they are deeply customer oriented and the satisfaction of his needs.” (Philip Kotler)
