miniature shafts, pins dowels(4x4, 4x6,zirconia rollers 4x8, 4x11.8, 4x13.8, loose needles,cylindrical rollers,4x15.8, 4x17.8, 4x19.8,dowels pins 4x21.8, 4x23.8, 4x25.8, 4x27.8, 4x29.8, 4x34.8, 4x39.8).
locating bearings require large axial
displacement, and it is not technically or
economically feasible to harden and grind the
shaft surface, needle roller outer and cage
assemblies can be combined with separable
wider inner rings.
needle roller bearings are available in several designs including variants without inner rings.
the most important design variations are shown on the opposite page.
we supply high quality rollers with hardened
steel,all of the rollers had hardened. usually,
the material of needle rollers and cylindrical
rollers, is chrome steel 52100(HRC60-65) or
stainless steel 420 (HRC53-56), the material
of balls, is stainless steel 440C(HRC55-58).
in both inch and metric sizes. we also custom manufacture special dowel pins to your
specification, and will be pleased to offer our quotation upon receipt of your detailed
requirements.
pillow block bearings incorporate a bearing
into a specific type of housing and are
generally sold as a single unit. The outer ring
is intended to be stationary, with only the inner ring actually moving.
This type of bearing is well balanced and typically delivers long
service cycles without a great deal of user maintenance
we also manufactures precision cylindrical rollers and needle rollers according to customer's
drawing.
