Why you should choose spherical plain bearings

Why you should choose spherical plain bearings

Are you deciding if a spherical plain bearing is the right fit for your application? Triangle manufactures a variety of spherical plain bearings including flange bearings, pillow block bearings, pedestal bearings, hanger bearings and more. 

Benefits of spherical plain bearings

Spherical plain bearings weigh less

A spherical plain bearing weighs half that of a similar-sized needle or roller bearing. 

Spherical plain bearings are cost-effective

Roller or needle bearings can be more expensive than a spherical plain bearing. This is due to their complex design and multi-component system. Add that to an increased tooling cost, and spherical plain bearings are the most cost-effective alternative. 

Spherical plain bearings are space-saving

Spherical plain bearings have a larger surface area than rolling-element bearings. Engineers can use space-saving smaller plain bearings that accomodate similar, and sometimes even heavier, loads than roller or needle bearings. 

Spherical plain bearings are a simpler design

Reduced parts and a simpler overall design result in lower maintenance with fewer components that can break or need repair. 

Spherical plain bearings are durable

Spherical plain bearings have a higher load-spreading capability compared to roller or needle bearings, can better withstand shock loads and can tolerate misalignment. 

Spherical plain bearings have an even distribution

Spherical plain bearings, even when slightly misaligned, do not concentrate loads on balls or rollers, but distribute them consistently and evenly. They accomodate small changes in pressure better than more complicated bearings. Learn how what to do if your spherical plain bearing is mis-aligned in Triangle's tutorial video.

Spherical plain bearings are lower maintenance

All of Triangle's spherical plain bearings are sintered and are oil impregnated with SAE30 non-detergent oil. This helps the spherical plain bearing stay lubricated throughtout its life-span which results in less maintenance for you.
