Through Hardened And Gear Broaching Outer Ring for Precise Grinding
of Deep Groove Ball Bearing System
Product:BOR3036 Deep groove ball bearing race
The 6005ND142RZ bearing is classified as a deep groove ball
bearing, featuring a characteristic deep groove structure in its
outer ring. This type of bearing typically consists of an inner
ring, an outer ring, steel balls, and a cage. A raceway is
incorporated within the outer ring to accommodate and support the
steel balls, facilitating smooth rotation. The 6005ND142RZ bearing
has an outer diameter of 52 mm, a width of 15 mm, and an inner
diameter of 25 mm. Furthermore, this bearing incorporates a sealed
design to prevent the ingress of dust and dirt, thereby extending
its service life.
Why the Outer Ring for Bearing from us:
Many years of know-how producing outer rings using cold rolling
process
Using the cold rolling process we save raw material up to 20% if
compared to standard process
Fiber flow are aligned to balls raceways due to cold rolling
process
Using the cold rolling process, the stock material is lower than
standard process
Parts are through hardening and ready for grinding
