What Is the FR8ZZ Hex Bearing

You use the fr8zz hex bearing when you want a strong and reliable part for your robot. This bearing fits a 1/2 inch hex shaft, which is common in many FRC robots. The hex shape inside the bearing helps your robot’s shaft turn smoothly without slipping. Rimao Bearing and RMO make this bearing for teams that need high performance and easy installation. You can trust this bearing to handle tough matches and long practice sessions.

Key Features

You get several important features with the fr8zz hex bearing:

• Hex Bore: The 12.7mm hex bore matches standard FRC shafts. You do not need a key for installation.
• GCR15 Steel: The bearing uses high carbon chromium steel. This material gives you strength and long life.
• ABEC-3 Rating: You get smooth and precise movement because of the ABEC-3 precision.
• ZZ Shields: Double metal shields keep out dust and dirt. Your bearing stays clean and works longer.
• Thicker Inner Ring: The inner ring is 30% thicker than standard bearings. This helps the bearing handle more force and reduces the chance of cracking.

Size

You need to know the exact size of your bearing to make sure it fits your robot. The FR8ZZ hex bearing has a 12.7mm (1/2 inch) hex bore. This matches most FRC hex shafts. The outside diameter measures 28.575mm, and the width is 7.938mm. These compact dimensions let you use the bearing in tight spaces on your robot. The thicker inner ring adds strength and helps the bearing handle more force during matches.

Material

The FR8ZZ hex bearing uses high-quality chrome steel, also known as GCr15. This material gives you excellent hardness and wear resistance. The steel cage inside the bearing keeps the balls in place and reduces noise. You get a bearing that lasts longer and works smoothly, even under heavy use. You can trust this material to handle the stress of robotics competitions. Chrome steel resists bending and cracking, so your bearing stays reliable through many matches.

Load Ratings

You want your bearing to support both radial and thrust loads. The FR8ZZ hex bearing is designed for high-stress robotics work. It has a static load capacity of at least 1.8kN. This means it can handle heavy weights and sudden impacts. The thicker inner ring helps spread the force, so the bearing does not crack under pressure.

Radial bearing strength lets your robot’s wheels or arms spin smoothly under weight. Thrust bearing support helps when your robot faces side forces or bumps. Always use steel hex shafts with these bearings. Steel shafts prevent deformation and help the bearing last longer.

Shielding

You need to protect your bearing from dust and dirt. The FR8ZZ hex bearing uses double metal shields (ZZ type) on both sides. These shields keep out contaminants and help the bearing run quietly. The shields also keep the grease inside, so you do not need to lubricate the bearing often.

How These Specs Help Your Robot

Each technical spec adds to the durability and performance of your robot. The precise dimensions ensure a perfect fit. The chrome steel material gives you strength and long life. High load ratings mean your bearing can handle tough matches and heavy parts. Double shielding keeps your bearing clean and running smoothly. When you choose the FR8ZZ hex bearing, you get a part that supports your robot’s success in every competition.

Environmental Factors

Robotics competitions can be dusty, dirty, or even wet. You need to keep your bearings safe from these tough places. The FR8ZZ hex bearing uses double shields to block dust and water. This design helps your bearing last longer and keeps your robot fast.

You should follow some easy steps to protect your bearings:

• Use shields or covers to keep out dust and water.

• Use the right grease to lower friction and wear.

• Check and fix shafts often to keep them straight.

• Pick materials that do not rust if your robot gets wet.

• Watch for trouble, like noise, shaking, or heat, and fix it fast.

The right care keeps your bearing safe from harm. Regular checks help you find problems before they get worse. If your robot runs hot or fast, pay extra attention to grease and shields.

You want your robot to do well in every match. By picking high temperature bearings and following good care steps, you help your team win. Always check your bearings for damage and keep them clean and greased. This care helps your robot handle speed, heavy loads, and hot places.

Application in Robotics

If you design custom parts with CNC or 3D printing, you can use this bearing for smooth rotation. It fits well in precision tools and small machines. The strong steel and thick inner ring help prevent damage, even with heavy use. You get a reliable part for many different applications.

You help your team or company succeed when you pick a bearing with a strong record and many uses.

Choosing the Right Bearing

You want your robot to run smoothly and last through many matches. Start with a good bearing selection guide. Look at the shaft size, load needs, and speed of your robot. The FR8ZZ hex bearing fits a 12.7mm hex shaft and handles high loads. Check if your robot needs double shields for dust protection. If you use your robot in a dirty place, double shields help keep the bearing clean. Always match the bearing to your robot’s design and the tasks it will do.

Installation Tips

You get the best results when you install the bearing the right way. Work in a clean area to keep out dust and dirt. Use the right tools to avoid damage. Hot-loading helps the bearing fit better on the shaft. Wear gloves to protect the bearing from rust and scratches. Make sure the shaft is straight and smooth before you install the bearing. If you see any dents or rough spots, fix them first.

Maintenance

You keep your robot running well with regular maintenance. Check your bearings often for signs of trouble. Watch for these signs:

• Excessive noise from the bearing

• Increased vibration during operation

• Overheating of the bearing

• Visible wear or damage on bearing surfaces

If you notice any of these, you may need to clean or replace the bearing. Good lubrication is important. Use the right grease to lower friction and stop overheating. Clean the bearing if you see dirt or dust. Always check for rust and fix it fast. Regular maintenance and proper lubrication help your bearing last longer and keep your robot ready for action.

You now know the most important specs of the FR8ZZ hex bearing. The hex bore, GCr15 steel, ABEC-3 rating, and double shields help your robot perform better and last longer. When you choose bearings from RMO, you get proven quality.
