Linear motion bearings are one type of bearing. Because there are
too many types of bearings in the bearings, the proportion of bearings
in today's industry is very large.
The
linear motion tumbling support is a pair of tumbling resin base steel
ball retaining ring elements formed between the relative movement parts.
The tumbling conflict is the most important between the moving parts.
Therefore, the reciprocating bearing has a small conflict factor, is
easy to start, and has an active action. ,
Long service life, low energy consumption and easy to produce flaws;
linear motion tumbling support for flat reciprocating linear motion
guide and circular guide Bu, to replace the sliding tumbling, but its
development is far behind the tumbling bearing Although
foreign countries have developed relatively early and have relatively
complete products of copper-clad alloy bearings and special-purpose,
cattle-manufacturers of certain planning, overall, no matter whether
they are structural types, specifications or types, they are still far
less productive and use. Rolling axis demand, the degree of standardization is also
relatively low, and the complete normative system has not yet been
completely established.
China's
linear motion tumbling support started later than in foreign countries.
Recently, there are fewer types of goods and specifications, and the
production plan is not large. The construction of various types of goods
is very unbalanced, and some of the products are produced in series:
such as circulating roller guides. Support, linear motion ball bearings. Some have not yet constituted volume production. In
recent years, the tumbling support of linear motions has developed
rapidly, and the world standardization organization has also formulated
some specifications. It
is mainly used for small collisions, active movements, smoothness, high
precision, high load carrying capacity, mechanical components that do
linear motions, persuade mechanical processing, CNC machine tools,
electric spark plus [: machine tools, high-speed, fine-machining
machines and slider guides The instrument expresses the category of recording equipment, automatic tailing machines, and guide columns for stamping dies.
