needle roller bearings are separable radial

bearings with very low sectional heights that

feature high load carrying capability. Needle

roller bearings use long, slim rollers, the so

called "bearing needles" as rolling elements.

Due to the possibility of mounting inner and

outer rings of needle roller bearings separately, mounting becomes much simpler, even under

the conditions of mass production. The comparatively thin - walled needle roller bearing rings

are usually mounted with tight fits.

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.

more stock,such as diameter 2,3,4,5,6,7,8,8,10

(mm)etc. please E-mail to us. for continuously

updating every day, any detail of the rollers,

please send E-mail to us.

we also manufactures precision cylindrical rollers and needle rollers

according to customer's drawing.
