Pu friction disc

Types of PU Friction Discs

The purpose of the PU friction disc is to generate adequate braking force by creating contact with the braking calliper or shoe. Friction discs are produced in two different types. They are:

• Flexible PU Friction Discs

  Friction discs with flexible design allow the use of angle grinders in a wide arcing radius. Hence, they are superb for variety of uneven surfaces and free-spinning tool utilization. Another advantage is reducing operator fatigue along with the teammate's physical and mental wellbeing through a more low-impact approach when grinding. This helps to lessen exposure to high vibration levels that could potentially result in harmful long-term effects on health. Thus making them an ideal pick for those who consider comfort as well important while still getting top-notch job done right.

• Rigid PU Friction Discs

  Rigid PU friction discs have a more limited scope of use because they are restricted to particular tasks like working on flat surfaces as well as metal finishing. Such heavy-duty discs provide outstanding support for precise results when accomplishing usual objectives through demanding operations requiring the utmost accuracy to meet specified standards. Their robust design caters explicitly towards tackling these kinds of challenges effectively, making them suitable choices among other options available for achieving desired outcomes during processes where maximal efficacy is needed consistently throughout various activities that involve often putting them into action.

Specifications & maintenance of PU friction discs

Specifications

• Material composition:

  PU friction discs' core material is typically a resilient plastic known as polyurethane. This material is prized for its ability to withstand wear and tear while maintaining a good grip on the surface of the brake pads and drums, thereby extending its lifespan.

• Sizes and shapes:

  Sometimes, one size doesn't fit all. PU friction discs come in various sizes and shapes to suit different vehicles. The most common are round discs that fit snugly inside the vehicle's braking system. However, other variations, like elongated or custom-shaped discs, may be available for specific vehicle models.

• Softness:

  One interesting feature of PU friction discs is that they come in different softness levels. Some discs are soft and flexible, which provides a gentle grip on the brake pads. Others are harder and more rigid, offering a stronger and firmer grip. Depending on the vehicle and the driving conditions, the choice between softness levels can significantly impact performance.

Maintenance

Regular maintenance is essential for optimal performance. Here's a simple maintenance guide to ensure the PU friction discs last long and perform well:

• Regular Cleaning:

  Use a soft brush or microfiber cloth to remove dust and debris gently. Regular cleaning prevents the build-up of dirt that can affect the performance of the discs.

• Inspect for Damage:

  Frequently, check the discs for signs of damage or wear. Look for cracks, breaks, or excessive wear. If any damage is detected, promptly replace the discs to avoid further damage to the braking system and ensure safety.

• Proper Storage:

  When not in use, store the PU friction discs in a cool, dry place away from direct sunlight or heat sources. Improper storage can cause warping or damage, reducing their effectiveness.

• Use Compatible Products:

  Make sure to use PU friction discs that are compatible with the specific make and model of the vehicle. Using the wrong type of disc can lead to poor performance and damage.

Scenarios

PUR is a hard, resilient plastic-like material. It is used to make discs for power sanding, which is used for the following purposes:

• Woodworking: Power sanding discs are mainly used on orbital sanders. Disc sizes are determined by the type of sander used. Home carpenters and professional craftsmen use sanders to smooth wood, shape edges, remove paint, and prepare surfaces for finishing. Friction discs used on sanders are cut and trimmed to perfectly match the sanding pads. ADSW sanding friction disc has a hook-and-loop attachment, which firmly attaches to the sander disc pad.
• Automotive Repair: Power sanding discs with mesh sanding discs for body filler are widely used in automotive repair when restoring classic cars or repairing accident-damaged vehicles. Repairers use sanding discs to remove paint, smooth surfaces, and repair rusted metal areas before repainting. As mentioned before, mesh offers superior dust extraction and often results in smoother finishes. Besides, fewer scratches are left on the surfaces to be painted. This will save a lot of time and money in the final preparation process prior to painting the car.
• Metalworking: Friction sanding discs are not limited to wood-only use. Metalworking professionals also have a place for sanding discs when polishing or grinding metal surfaces. Without doubt, sanding discs are time-saving and efficient metal surface treatment tools.
• Floor Refinishing: Floor refinishing professionals usually make use of large sanding discs, mostly in 400-500 mm sizes for orbital floor sanders. Friction sanding discs can be used on various floor surfaces, including wooden floors, marble, and concrete.

How to choose PU friction discs

When choosing products, quality and performance should be the primary consideration. Aim to select a product that would serve many purposes but at a reasonable price. The following tips will help one choose the suitable PU friction disc for people’s needs.

• Payload Capacity and Safety Factor

  Choose a disc brake system's application-specific PU friction discs. Consider the working loads and select a task-specific one. Select a safety factor. This requires working-load calculation. A lower safety factor is acceptable for non-critical applications where the risk of load exceeding is low.

• Friction Coefficient and Pad Design

  Select the right balance between noise, wear, and brake performance. Choose PU discs with different friction coefficients based on the vehicle's type and driving style. Know whether one prefers low-dust organic pads or high-performance metallic ones.

• Environmental Resistance

  Temperature tolerance: Check the pads' temperature range to ensure proper braking performance. Moisture resistance: Consider the water resistance of the PU discs. Avoid pads that deteriorate when exposed to moisture.

• Compatibility and Sizing

  Checking if the PU friction discs are compatible with calipers and rotors is essential. Inspect the dimensions to guarantee the right fit. Ensure part numbers match the specifications of the vehicle or machinery.

• Brand Reputation and Certification

  Choose reputable manufacturers with good brand recognition in the industry. Research their track record, customer reviews, and reputation. Consider products endorsed by relevant certifications or organizations.

Pu friction disc Q & A

Q1. What does a PU disc do?

A1. The PU discs are used for polishing and finishing. They are usually utilized in the final stage of polishing where an outstanding luster is required. The edges of the discs are felted or cushioned to give better results.

Q2. Are polyurethane discs better than plastic?

A2. Polyurethane (PU) is a material that has considerable durability and resistance as well as the ability to absorb impacts, far exceeding that of ordinary plastic. Ordinary plastic is easily deformed and has little buffer elasticity.

Q3. Are discs the same as wheels?

A3. Discs are generally flat components, circular in shape and thin. Common examples include brake discs, friction discs, washers and gaskets. Wheels, on the other hand, are round solid objects that rotate and are built to roll over surfaces.
