manufacture of precision spherical rollers or spherical roller bearings! supplier of loose spherical rollers and convex rollers in china.
the spherical rollers that are thicker in the
middle and thinner at the ends,spherical
rollers are difficult to produce and thus
expensive.
we are manufactured precision rollers psrts. including cylindrical
rollers,spherical rollers, needle rollers, tapered rollers, cuspidal ends rolles, arc correction line
rollers, logarithm profile rollers etc. we will provide you quality needle roller with competitive
price and excellent service.
In many highly stressed applications the
cylindrical roller cannot be “too cylindrical” –
otherwise severe edge loading will occur. Perfectly cylindrical surfaces
in contact always have higher stresses at the edges. Furthermore, this
edge loading can worsen if the roller is slightly misaligned or if the
components bend or distort during operation.
by putting a tightly controlled “crown” on the roller at the micrometer level, the loading of the
bearing can actually be made more consistent over the length of the bearing. The following
figures show how different types of surface profiles induce different kinds of contact stresses
at low and high loading.
This type of bearing utilizes cylindrically
shaped rollers as the load carrying element.
This bearing type is designed to carry large radial loads. This bearing,
in its basic configuration, is not well suited to counter axial loads. The rollers may actually be
slightly barrel shaped in certain designs. Barrel shaped rollers and their associated outer race
allow for some self alignment of the bearing. Needle bearings are a special adaptation of the
cylindrical roller bearing.
