Introduction to the LC SERIES precision gearbox

The LC Series precision gearbox represents the ideal entry point into the world of high-quality mechatronics. Designed by Bonfiglioli to meet the needs of those requiring accurate positioning without facing the costs of top-of-the-range models, the LC series stands out for its incredible versatility. Choosing an LC precision gearbox means opting for a successful product capable of combining limited backlash with high torque density.

This planetary gearbox has been developed to be coupled with the most common servomotors on the market, transforming speed into torque with a precision that makes it number 1 in its market segment. Its compact structure makes it perfect for integration into machinery where space is a critical factor.

Valuable technical features of the LC Series

The true value of the LC precision gearbox lies in its optimized engineering. Despite its competitive positioning, it does not compromise on material quality or gear precision.

Here are the technical specifications that make the LC Series an excellence solution:

• Reduced Backlash: Available with standard backlash levels that satisfy most industrial automation applications.

• High Torque Capacity: Thanks to the 3-planet planetary system per stage, it distributes the load evenly.

• Flexible Design: Available in various sizes (LC 050, LC 070, LC 090, LC 120, LC 155) to cover a wide range of needs.

• Variable Reduction Ratios: Wide choice of ratios (from 3:1 up to 100:1) to optimize the dynamics of the servo-controlled axis.

• Lubricated for Life: Supplied already lubricated with synthetic grease to eliminate routine maintenance.

Effectiveness in positioning and axis control

The use of the LC Series precision gearbox is particularly effective in all those applications where smooth and repeatable motion control is required. In assembly lines, pick-and-place systems, or printing machines, the torsional rigidity of the LC Series ensures that the software command is instantaneously translated into mechanical movement.

Another fundamental aspect is its energy efficiency. LC precision gearboxes boast very high efficiency ratings (up to 97%), reducing power losses and limiting the overall heating of the system. This factor, combined with operational silence, makes it a successful choice for machine builders aiming for efficiency and operator comfort.

Construction design and Bonfiglioli reliability

Every LC Series precision gearbox is the result of cutting-edge production processes. The gears are made of alloy steel and subjected to precision heat treatments to ensure surface hardness and wear resistance. The external housing is designed to ensure excellent thermal dissipation, protecting the integrity of the connected servomotor.

Advantages of the LC Series design:

1. Universal Mounting: Thanks to the modular input flange, coupling with the motor is quick and secure.

2. Robustness: Despite its lightness, the structure is designed to withstand significant radial and axial loads.

3. Output Versatility: Available with a smooth shaft or with a keyway to adapt to any type of pulley or coupling.

Ideal applications for the LC gearbox

Thanks to its exceptional performance-to-price ratio, the LC Series precision gearbox finds application in countless sectors:

• Light Automation Systems: Loaders, manipulators, and Cartesian axes.

• Packaging and Wrapping: Where speed and repeatability are essential.

• Wood and Plastic Machinery: For auxiliary movements and roller positioning.

• Educational and Industrial Robotics: For joints requiring precision but medium loads.

The adoption of this valuable technology allows you to make your machines competitive, offering final customers professional precision with a contained investment.
