Universal joint has lubricated needle bearings
A new design of needle bearing universal joint is practically maintenance free while operating precisely at high speeds for extended periods.
Miniature joints have universal appeal
A new range of high precision miniature joints are suited specifically for miniature machinery, medical equipment, model making and many applications in which space is restricted.
In UHV chambers, universal joints are often used for the handling or operating mechanisms that manipulate or move materials that are researched or modified in these chambers, or to control the process that is used for that.
Universal joints and complete shaft assemblies are manufactured from a variety of stainless steel grades, including AISI 303 (1.4305), 304 (1.4301) and 316L (1.4404) to prevent outgasing.
Outgasing is a major issue for UHV systems and can be minimised by utilising materials with low vapour pressure such as stainless steel.
The yokes of the universal joints as well as the pins and block are machined from the same selected stainless steel material.
The joint can be supplied free of grease and lubricants to minimise the effort necessary to clean the parts for installation.
Lubricants and a wide range of plastics are not permitted in UHV applications as the outgas of these materials hinders establishing ultra high vacuum.
Belden's speciality is custom assemblies made to specific applications and exact operating criteria.
