Acting as the essential low-friction interface between moving mechanical components, bushings (or plain bearings) are designed to support heavy loads while minimizing wear on vital machinery. They are the critical “sacrificial” element that ensures long-term system reliability.
Bushings are intentionally designed to wear down over time, protecting significantly more expensive parts like shafts and machine bores from damage. It is fast and economical to replace a bushing, rather than machining a new shaft.
By providing a specialized sliding surface (often self-lubricating or oil-impregnated) between moving metals, they drastically reduce friction and prevent components from galling or seizing up during operation.
Due to their large surface contact area compared to ball bearings, bushings can handle immensely high radial loads in designs where space is extremely limited.
They serve as guides to maintain the accurate positioning of a rotating shaft or a linearly moving rod, ensuring smooth motion and preventing undesirable wobbling or vibration.
The material properties of many bushings (especially composite or polymer types) allow them to absorb shock and assist in dampening operational noise and system vibrations.
Effectively absorbing small road vibrations and isolating noise, our bushings provide a much smoother and quieter ride. Choose these if you want your vehicle to feel less "hardcore" and more comfortable.
Our polyurethane bushings contain graphite additives and feature oil-retaining grooves on the inner walls, eliminating the squeaking noise often associated with traditional bushings.
Compared to soft OEM rubber, our polyurethane bushings are more resistant to corrosion, oil, and wear. They maintain their shape and strength over time, ensuring long-term reliability.
With a modular design, the bushing’s inner rubber sleeve and insert can be easily replaced without the need to replace the entire assembly, making maintenance cost-effective and straightforward.
Yes, they are more flexible, which means road feedback is less direct, but the comfort level is significantly higher.
Not at all. When installed with our sticky grease, they operate silently without any squeaks or noises.
Our bushings typically have a hardness of 88A or 95A, offering a balanced mix of comfort and support for handling.
Absolutely. They effectively reduce engine movement, improving power response and enhancing the overall driving experience.
Yes, we offer a variety of standard sizes, including different diameters and widths, making them compatible with custom linkages and suspension builds.
We accept T/T, PayPal (for samples), and L/C for large orders. For new customers, 30% deposit and 70% before shipment is standard.
