Design and Characteristics of Ball and Roller Bearings

SINGLE ROW DEEP GROOVE RADIAL BALL BEARINGS  are the most widely used bearings and utilize an uninterrupted raceway, which makes these bearings suitable for radial loads, or a combination of radial and thrust loads.  This design permits precision tolerances even sat high speed operation. The cage in this bearing is pressed steel.  For high speed bearings, machined brass cages are available.  Bearings with locating snap rings...

Some Fun Facts about Bearings

While it’s true that bearings might not come up in everyday conversations, they may never be the theme at Bingo night, or even come up during a heated game of trivia – but there are definitely a few things about bearings you don’t yet know, and they are far from boring! Bearings Aren’t New Nowadays Yes, there are many new ways we’ve found to implement the handy little buggers, but that’s not to say bearings haven’t in fact been around a very long...

How to Calculate Friction in a Sleeve Bearing

The friction present in a sleeve bearing depends upon several factors. For example, the constant value of the coefficient of friction depends upon what materials comprise the sleeve and bearing. Other important factors include the size of the shafts, the rotational speed and the lubricant viscosity. In a rolling-element bearing, its static friction (and the torque needed to overcome that force) usually exceeds its running friction. Consider all...
