YDTech® manufacturer of loose columnar ceramic rollers and cylindrical roller bearing; supplier of cylinder rollers for axial bearing parts as rolling element units in china.
What's cylindrical roller?the cylindrical rollers, it is meaning the outer
surface is substantially straight and parallel to
the axi of the roller. the cylindrical rollers are
precision parts for bearing.
we have over 20 years of manufacturing experience of precision rolelrs. we had most stock,
delivery time: send to europe, USA, or canada only 3-5 work days
through some special machines and
production process. we have solved the
problem how to make ultrashort, special
chamfer and round cylindrical rollers in mass
production.
cylindrical rollers are remarkable for their high mechanical strength and long lasting functional
life. cylindrical rollers had multiple uses in a variety of industries including automotive, truck:
linear lead rails, ultra-thin bearings, needle bearings, one way clutches, one-way bearings,
needle bearings ,subminiature motor and so on.
the ground ends needle rollers are mainly
used as bearing rolling elements to transmit
torque and reduce friction. they can also serve
as precision shafts or as precision locating
pins
