Needle Bearing
¡@
¡@
Definition of Needle bearing Needle roller bearings are roller bearings with cylindrical
rollers that are small in diameter. In spite of their low cross section, needle
roller bearings have a high load carrying capacity and are therefore extremely
suitable for bearing arrangements where radial space is limited. Contour surface
have a slight contraction?in the proximal surface of needle. Modification of
needle and roller line contact results in preventing destructive edge stress.
all can be used for general engineering bearings except catalog listed as
following: Drawn cup needle roller bearing Combined needle roller bearing. Code and structure characteristics
(1)open drawning cup needle needle roller bearing (2) sealed needle roller
bearing (3) needle bearing with inner ring (4) needle bearing without inner
ring. SKF can also proveide various types of needle bearings.such as: 1. Needle
roller cage assemblies 2. No raised edge needle bearing 3.self-aliging needle
bearings 4. Combined needle roller / ball bearings 5. Combined needle roller /
thrust ball bearings 6. Combined needle roller / cylindrical roller thrust
bearings
Drawn cup needle roller bearing is a needle
bearing which outer ring is extremely thin stamping. Its main characteristic is
lower depth of section but higher load capacity. Mainly used for compact
structure, cheap price and inner hole can not be used as configuration in needle
cage raceway. Bearings and bearing box shall be installed on interference fit
way. If can leave out box shoulder, stoperring such kinds of axial orientation
function, therefore, inner hole of bearing box can be made simply and
cost-efficient. Such as KH series and BK series.etc.
Combined needle roller bearing includes NKIA
type, NKIB type, NX.. Z type, NKX type, NKX.. Z type, NKXR type, NKXR.. Z type,
NARN type and ZARF type.
K/KS single single/profile fraction
KK/KKS double row/double row cutting fraction
KZK connecting with crank pin
With KBK connecting rod piston pins
KNL long cylindrical roller and retainer components
