中文简体The miniature precision ball bearings are widely used in a variety of industries. They are designed for vacuum environments and are also suitable for corrosive environments. They are suitable for high speed applications and perform in demanding conditions. They are also used in applications that involve cryogenic temperatures. Amongst their features are: radial balls, an extended outer ring, an eccentric bearing, a snap ring on the outer ring, self-aligning, and an internal periodic lubrication system.
One of our customers, a manufacturer of custom screwdriving spindles, had been purchasing a standard-sized miniature thrust ball bearing from a large bearing manufacturer for many years. However, the bearings were failing and the customer was frustrated with the loss of time and productivity. They wanted to find a new solution that would protect the bearings from debris and keep the lubrication in. They also wanted a solution that would increase the life of the bearings.
It is frictionless, offers excellent dynamic behavior, and is a closed-loop system that works with a high performance motion controller. It can be combined with a fine pitch non-contact linear optical encoder to give the system unlimited service life.
The new solution also prevented the customer from having to replace the bearings on a regular basis. The bearings were used in a high-volume application, with 20-30 bearings per month. The average life of the open style bearings was three months. The new solutions reduced the maintenance costs by more than 200%. They were also less costly to manufacture.
Its noncontact design and compatibility with a variety of motion controllers makes it ideal for scanning, optics positioning, and other high-speed applications. It can be mounted vertically or with a pneumatic counterbalance.
