Chrome Steel Gcr15 Knitting Machine Cylindrical Roller Bearing 130*140*44mm
NNU4926 knitting machine bearing product description:
Double Row Cylindrical roller bearings as for the ring ribs divided into N-type,NU type,NJ and NUP type and so on.Cylindrical roller bearings withstand heavy capacity of the radial load.But according to the structure of ring ribs can also be under some one-way or two-way axial load.
I. Bearing ring product features:
Strong work load ability, strong hardness HRC60~65.
Long worklife at leat 10000 work hour guranteed.
Our material heat treatment, excellent forging raw material.
Bearing ring surface anti-corrosive treatment.
Inner tolerance could reach to 0.001mm.
II. Bearing ring product brief introduction:
We product bearing inner rings as per customer drawing, material and tolerance according to buyer request.
Forging raw material for bearing rings, turning and grinding process by CNC precision machine.
With standard heat treatment working process, to guarantee our bearing hardness reach HRC60~HRC65.
Using excellet steel raw material to guarantee the tolerance of bearing rings boundary dimensions.
III. Inner bearing rings product Applications:
Make replacement for damaged bearing rings for milling machines, huge equipment, large agriculture machine. For repair market usage, or maintainance market of bearing.
NNU4926 bearing is used in knitting machine, double row cylindrical roller bearing.
We using forging material for our bearing rings.
The difference between forging and casting material:
The casting metal is formed in liquid casting and casting. It requires good fluidity, filling ability of liquid metal, etc. (also called casting), divided into two cast steel and cast iron in the iron and steel casting, iron carbon content is higher than steel, its low strength over steel, plastic, poor general tolerances for the production is not very big parts, such as machine tools, such as the low pressure valve; Steel casting strength is high, used for making complex parts, such as chain rail, high pressure valve seat, etc.
Forging is formed by forging after the metal is heated in solid state. It requires the metal to have good thermoplastic (also known as forging), and the general forging is steel, which is of high strength and plasticity, which is suitable for high quality and high quality components. Such as bolts, shafts, gears, axle, etc.
IV. Product Quality Checking:
100% checking during producing process,random checking before delivery.
