Universal joints have remained virtually unchanged for a century. The new approach from CCTY Bearing Company simplifies the design by replacing many central components with one – a square ball.
The novelty of a square ball can raise a few eyebrows. When it smoothly oscillates in a universal joint, mechanical engineers want more details.
Bearing manufacturers have a number of skilled engineers on staff – along with people who have been in the industry for decades. One of the great things about having these folks as coworkers is the way that they are able to explain complex concepts.
Grease is what keeps moving parts in motion. Traditionally, u-joints are outfitted with lip seals to help retain the grease. The lip seal also allows for regreasing and usually acts as a barrier to prevent contaminants like dirt and moisture from getting into the unit.
Wondering how the Square Ball Universal Joint compares to traditional ujoints? This side-by-side comparison walks though the differences between the two designs.
