Bearings
●Exceptional Load and Shock Resistance: Composite bearings possess inherent elastic properties, enabling them to withstand high-load and high-shock conditions. Unlike rigid metals or bronze bearings, they can accommodate significant compression, shock, and vibration without deformation.
●Outstanding Temperature Performance: Composite bearings excel in a wide range of temperatures, from cryogenic levels to +330°F, depending on whether they are subjected to continuous or intermittent operating conditions. This makes them suitable for applications involving extreme temperatures where metals may fail.
●Enhanced Dimensional Stability and Corrosion Resistance: Unlike metal and bronze plain bearings, composite bearings are highly resistant to rust and corrosion caused by exposure to liquids and chemicals. They can withstand most solutions with minimal pitting or swelling, ensuring long-lasting performance.
●Low Friction Bearings: Composite bearings boast impressive friction performance, with coefficients as low as 0.05 in dry applications and 0.02 in lubricated environments. This makes them a reliable option for applications where friction is a critical concern.
Washers
●Washers Divide Weight: When you add a washer, the force exerted by the fastener is spread out over a larger area, reducing the potential for cracks due to pressure and stress.
●Washers Enhance Space: Washers help to ensure that the bolts and screws fit snugly. By threading the fastener through the washer before installation, you ensure that the fastener doesn’t go too deeply into the surface material.
●Vibration Reduction: Vibration isolation washers are manufactured using soft vibration-absorbent materials like rubber or plastic. They help to absorb vibration, reducing the amount of stress applied to the fastener and surrounding equipment.
●Leak Protection: By creating an airtight, watertight seal, washers can prevent liquid from leaking around the drilled fastener holes in plumbing and process piping and connections.
Application of Bearings And Washers
Washers
●Load Distribution: Fasteners exert high levels of force when installed. Washers help to distribute that load to prevent damage to the material. Without washers, materials are more likely to crack due to tightening pressure.
●Spacing: If the length of the bolt or screw is greater than the object’s thickness, it is impossible to sufficiently tighten the fastener without the screw protruding from the other side. By adding washers, you can create enough space to prevent the fastener from going too far into the substrate.
●Absorbing Vibrations: Washers made from plastic or rubber absorb vibrations in high vibration applications. Vibration reduction keeps the fasteners from loosening over time and helps to protect the attached equipment from vibration damage.
●Sealing Connections: Washers can be used to seal joints on piping, tubing, and ductwork, to create a waterproof seal that prevents gas or fluid leakage.
Bearings
●Automation and robotics:In automation systems, precise movement and stability are critical. Flanged bearings are commonly used in robotic arms and conveyor systems to ensure smooth and reliable operation.
●Aerospace and automotive:In aerospace and automotive industries, flanged bearings provide stability and resistance to vibrations, ensuring critical components perform reliably under demanding conditions.
●Manufacturing and processing machinery:Flanged bearings are used extensively in manufacturing environments, from packaging machines to assembly lines. Their ability to handle axial loads and maintain alignment under stress makes them invaluable.
