miniature shafts, pins dowels(D4.0, D4.1, needle bearingsD4.2, D4.3, D4.4, D4.5, D4.6, D4.7, D4.8, D4.9)! miniature needles,ceramic rollers,(D4L11.8, D4L13.8,Si3N4 pins D4L15.8, D4L17.8, D4L19.8, D4L21.8, D4L23.8, D4L25.8, D4L27.8, D4L29.8, D4L34.8, D4L39.8).

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
