In the world of robotics, particularly in the FIRST Robotics Competition (FRC), precision, durability, and efficiency are paramount to ensuring that robots perform at their highest potential. Every component, from motors to wheels, plays a crucial role in the robot's overall success. One often overlooked but vital component is the bearing, specifically the hexagonal bore bearing. While traditional round bearings have been used for years, hexagonal bore bearings offer unique advantages that can significantly improve an FRC robot's performance. In this article, we’ll explore how hexagonal bore bearings contribute to a more efficient and durable FRC robot design.
1. What Is a Hexagonal Bore Bearing?
A hexagonal bore bearing is a type of bearing that features a hexagonal-shaped hole, rather than the standard round bore. The hexagonal shape allows for a tight fit with corresponding hexagonal shafts, often seen in the drivetrain and other moving parts of FRC robots. This fit enhances the transmission of torque and reduces the likelihood of slippage or rotational play, leading to smoother and more precise movement. Rimao has developed a non-standard product Fr8zz Fr8 hexagonal bore bearings specifically for FRC robots after many technical improvements.
Hexagonal Hole: The main difference between hexagonal bore bearings and traditional round bore bearings is the shape of the central hole, which matches a hexagonal shaft.
Secure Fit: This fit ensures that the bearing stays firmly in place without sliding or rotating independently of the shaft, contributing to more reliable performance.
Improved Torque Transmission: The fit helps transmit torque more effectively, especially in high-load situations common in FRC robotics.
Now that we understand what hexagonal bore bearings are, let’s look at the benefits they bring to FRC robot performance.

2. Improved Torque Transfer and Power Efficiency
Torque transfer is crucial in FRC robots, especially when dealing with high-power motors and demanding tasks such as lifting, pushing, or rotating. Hexagonal bore bearings offer a more efficient way to transfer torque compared to traditional round bore bearings. The key benefit lies in the hexagonal shaft that locks into the hexagonal bore, creating a more secure connection. This improved fit reduces the risk of slippage, which is common when using round bearings with square or hexagonal shafts.
Secure Torque Transfer: The hexagonal fit ensures that power is transmitted more reliably without loss due to slip, which is especially important for high-torque applications.
Reduced Friction: The reduced slippage minimizes friction, contributing to a more efficient use of power and less energy wasted on unnecessary movement.
Optimized Performance: With torque efficiently transferred, motors and other components can operate at their optimal levels, ensuring smoother and more responsive movements.
By providing better torque transmission, hexagonal bore bearings help FRC robots achieve higher power efficiency, which can make a significant difference in competitive environments where every ounce of power counts.
3. Enhanced Precision and Control
Precision and control are fundamental in FRC competitions, where robots are required to perform delicate maneuvers, lift heavy objects, or navigate complex terrain. A hexagonal bore bearing improves the accuracy and consistency of these movements by ensuring a tighter connection between the bearing and shaft. This minimizes any unwanted movement or play, which can negatively affect the robot’s ability to perform precise tasks.
Eliminates Shaft Slippage: The hexagonal shape prevents any unwanted rotational play, ensuring that the bearing moves exactly with the shaft, without any slip.
Stable Movements: The more secure fit contributes to steady and predictable motion, which is vital for tasks requiring high precision, such as aiming or object manipulation.
Improved Positioning: The tighter connection reduces the likelihood of misalignment, helping to ensure that all parts of the robot are in the right position for optimal performance.
When you need pinpoint accuracy in a competition, hexagonal bore bearings provide the stability required to execute critical actions with precision and reliability.

4. Increased Durability and Wear Resistance
In FRC, robots face intense physical stress throughout the competition season, with repeated use, high speeds, and heavy impacts. This puts a lot of strain on the robot's components, including bearings. Hexagonal bore bearings, with their secure fit and reduced risk of slippage, tend to experience less wear over time compared to traditional bearings. The added durability can help keep the robot running longer without the need for frequent maintenance or part replacement. Rimao hexagonal bearings have more material between the hexagonal holes and raceway edges, making them stronger and less likely to break under high loads.
Reduced Wear and Tear: Since there is no slippage between the shaft and the bearing, there is less friction and, therefore, less wear on the bearing itself.
Stronger Connection: The tight fit means that the bearing is less likely to shift or move out of place, even under heavy loads, contributing to its longevity.
Longer Lifespan: With less wear and tear, the hexagonal bore bearings will last longer, reducing the frequency of replacements and ensuring more consistent performance throughout the season.
Durability is a key factor in FRC, where robots face extreme conditions. Hexagonal bore bearings offer the reliability and longevity needed to withstand those challenges.
5. Better Integration with FRC Robot Systems
FRC robots often feature intricate designs with multiple interconnected systems, including drive trains, manipulators, and lifting mechanisms. Hexagonal bore bearings are designed to integrate seamlessly with the hexagonal shafts that are commonly used in these systems. This makes them a natural choice for FRC teams looking to build robust and efficient robots.
Seamless Compatibility: Many FRC components, such as wheels, gears, and sprockets, are designed to fit hexagonal shafts, which makes hexagonal bore bearings a perfect match for these systems.
Modular Design: Hexagonal bore bearings can be used in various applications across the robot, allowing teams to maintain consistency in their design while optimizing performance in different areas.
Easy Assembly: The ease of assembly with hexagonal bore bearings ensures quicker builds and easier maintenance, which is particularly important during the intense build season leading up to competitions.
By matching the standard hexagonal shafts used in many FRC parts, hexagonal bore bearings simplify the integration process, saving time and effort during both the design and build stages of robot development.
6. Cost-Effective Solution
Cost is always a consideration in FRC, where teams often work with tight budgets. Fortunately, hexagonal bore bearings offer a cost-effective solution for improving robot performance without breaking the bank. These bearings are typically affordable and provide a significant performance boost without requiring expensive, specialized parts.
Affordable Performance Boost: Compared to custom-designed bearings or higher-end alternatives, hexagonal bore bearings are relatively inexpensive while still offering major performance improvements.
Available in Bulk: Many suppliers offer hexagonal bore bearings in bulk, making them a cost-effective choice for teams needing multiple bearings for various parts of the robot.
Reduced Maintenance Costs: The increased durability of hexagonal bore bearings leads to fewer replacements, reducing long-term maintenance costs.
Hexagonal bore bearings offer an affordable way to enhance robot performance, making them a great option for teams with limited resources.
7. Conclusion
Hexagonal bore bearings are an essential component for FRC teams looking to maximize their robot's performance. With benefits such as improved torque transfer, enhanced precision, increased durability, and easy integration, these bearings provide a cost-effective way to optimize robot design and functionality. Whether you're building a high-speed drive train, a precise manipulator, or a reliable lifting mechanism, hexagonal bore bearings offer a proven solution to help your robot perform at its best.
