At Mankoo Machine Tools, we design and manufacture high-performance Pinch Rolls & Tail Breakers that serve as critical components in high-speed TMT rolling mill lines. Engineered for maximum efficiency, control, and durability, these systems ensure smooth bar transportation, maintain ideal tension, and enable precise direction and alignment of hot rolled products through various mill stages.
Our Pinch Roll units, equipped with heavy-duty gearboxes, high-torque motors, and adjustable roll pressure systems, provide consistent grip and acceleration of bars post-rolling and prior to shearing or cooling. These rolls play a key role in stabilizing bar movement at critical points—particularly post-quenching and before entry into twin channels or cooling beds—minimizing slippage and ensuring uninterrupted downstream operations.
The Tail Breakers, placed strategically to slow down and decelerate the tail end of bars after rolling, are essential for protecting equipment from impact damage and ensuring smooth handoff to the cooling system. These are integrated with automation-ready control systems, allowing seamless synchronization with mill speed and bar positioning sensors, enhancing overall plant responsiveness and safety.
Constructed from high-grade alloy steel with wear-resistant rolls and sealed bearings, our systems are built for longevity and minimal maintenance. With options for hydraulic, pneumatic, or motorized adjustment, they offer maximum versatility across product sizes and speeds.
Whether installed as part of a new rolling mill or retrofitted into existing setups, Mankoo’s Pinch Rolls & Tail Breakers offer unmatched control, safety, and operational efficiency—delivering the performance needed for next-generation steel manufacturing.
Our Pinch Roll units are precisely engineered and strategically positioned at critical transition points within the rolling mill—such as before and after the quenching box, near the dividing shear, and just ahead of the cooling bed. These locations are essential for applying controlled tension, ensuring bar stability, and facilitating the smooth and accurate transfer of hot rolled TMT bars through each stage of the production line.
By delivering precise grip and speed regulation, the pinch rolls help maintain a steady bar trajectory, prevent unwanted looping or sagging, and minimize the risk of cobbles or bar entanglement. This results in cleaner cuts, better synchronization with shears and twin channels, and overall improved mill uptime.
Each pinch roll unit is equipped with robust drive systems, adjustable pressure mechanisms, and wear-resistant rolls designed to handle high thermal and mechanical loads. Whether it’s the high-speed bar exit from the last finishing stand or the sensitive transfer near the shear, our systems are tailored to ensure optimal control and seamless coordination throughout the entire process.
Ultimately, our pinch roll solutions not only enhance safety and product quality but also reduce operator intervention and maximize the mill’s productivity and efficiency—making them indispensable for any high-performance TMT rolling setup.

Our Pinch Roll systems are meticulously crafted to meet the rugged demands of high-speed, high-temperature rolling environments. The foundation of each unit is a heavy-duty, fabricated mild steel base that provides structural integrity and vibration resistance, even under continuous load. The wear-resistant, graded cast iron rolls are precision-machined to deliver optimal gripping performance, durability, and heat resistance, ensuring long operational life with minimal maintenance.
Designed with versatility and precision in mind, we offer both cantilevered and pneumatic-type pinch rolls, each tailored to suit different rolling configurations and mill layouts. These units are capable of handling bar sizes up to 360mm center roll spacing (CRS) and are equipped with fine-tuned vertical adjustment mechanisms to maintain consistent pressure on the bars, regardless of diameter or temperature fluctuations.
Our pneumatic-type pinch rolls utilize automated pressure regulation systems to dynamically adjust the roll pressure based on bar speed and material characteristics, ensuring uniform bar alignment and smooth transfer throughout the rolling line. The cantilevered versions are particularly effective for quick roll replacement and simplified maintenance in high-throughput operations.
Whether installed before the quenching line, after the last finishing stand, or ahead of the dividing shear, Mankoo’s pinch roll systems are engineered to optimize performance, reduce wear, and support the uninterrupted flow of material—even under the most demanding production schedules. This robust construction and intelligent design make them a key contributor to overall mill efficiency, safety, and product quality.
Our Tail Breaker System is a critical component in the rolling process, precisely engineered to safely reduce the speed of TMT bars after quenching and just before they enter the Twin Channel system. This transitional stage is crucial for ensuring smooth and controlled bar handling, particularly at high rolling speeds.
Equipped with twin synchronized DC motors, the Tail Breaker delivers accurate braking torque, enabling gradual deceleration without causing bar distortion, bending, or surface damage. The motors are controlled through advanced electronic drives, allowing real-time adjustments to braking force based on bar speed, size, and mill throughput—ensuring optimal performance under all operating conditions.
Built on a robust structural frame, the Tail Breaker houses high-durability pinch rolls designed to withstand the thermal and mechanical stresses typical of post-quenching operations. The system’s precision bearings and adjustable roll settings further enhance control and minimize wear, contributing to longer service life and reduced downtime.
Incorporated into both conventional and high-speed rolling mills, our Tail Breaker plays a vital role in maintaining bar integrity, ensuring proper alignment, and preparing the product for the next stage of handling or cutting. With its compact footprint, intelligent design, and maintenance-friendly features, Mankoo’s Tail Breaker system represents the perfect combination of safety, efficiency, and durability for modern rolling operations.
At Mankoo Machine Tools, we combine mechanical engineering precision with advanced automation technology to deliver fully integrated solutions that elevate operational efficiency and performance. Our Pinch Roll and Tail Breaker units are equipped with state-of-the-art automation systems designed to seamlessly synchronize with the overall rolling mill workflow, ensuring consistent material flow, optimal tension control, and minimal manual intervention.
These systems feature intelligent PLC-based control panels, enabling real-time adjustments in speed, pressure, and positioning based on input from mill sensors and production parameters. With the integration of servo drives, encoders, and high-speed communication protocols, our automation setup ensures that every roll and breaker responds instantly to changing mill dynamics, maintaining precision bar handling throughout the process.
Additionally, features such as automated roll gap adjustment, remote diagnostics, and predictive maintenance alerts help reduce downtime and enhance reliability. The automation also includes safety interlocks and fail-safe mechanisms that protect both the machinery and operators during high-speed operations.
Whether it’s a new installation or an upgrade to an existing mill, our integrated automation ensures a seamless, synchronized, and future-ready solution—giving customers greater control, higher productivity, and peace of mind in demanding production environments.
Together, these systems minimize manual intervention, enhance safety, and maintain production continuity even at peak throughput levels.
