Beam Cutting Machine And Needle Roller Bearings What Are The Differences
Cylindrical roller bearings are precision bearings, precision sorting roller radial ring guide guide, by the cage, roller and guide shaft composition, with another bearing ring separation, are separable bearings. This kind of bearing installation, disassembly more convenient, especially when the requirements of the outer ring and the shaft, the shell is the interference with the show when the advantages of such bearings are generally only used with the radial load gun live ammunition, only the inner and outer Both single-row bearings with ribs can be characterized by high load, bottom noise and high speed, as the smaller steady-state axial loads or larger intermittent axial loads are the same as other dimensions. Very suitable for use with all kinds of precision machinery and mine rolling mill machinery. But with such bearings with the axis, rolling and other related parts need to be precision machining.
(NK, NKS, RNA49, RNA48, NKL, NKLS, NA49, NA48, RNA69, NA69, RNA49 ... RS, RNA49..2RS, NA49..RS, NA49..2RS, RNAO, NAO) Compact, radial size is small, the load capacity, bear a larger radial load. This type of bearing has a variety of structure and size series, the assembly of G2-level needle, the group batch diameter variation within 2um, in addition to full complement needle roller bearings, are used high-quality cage, can correctly guide the needle parallel axis The
Different structure, different types, different forces in different directions, different speed, different load, different materials, the application of different occasions, etc.
The difference between the tapered roller bearings is the tapered roller needle roller bearings are needle roller
The above fundamental difference determines the structure of the tapered roller bearing relative to the needle roller bearings, tapered roller in addition to radial force can withstand axial force, and needle roller needle roller bearings can only bear the radial force
Tapered roller bearings are divided into two rows and columns, respectively, applied to different environments and occasions
Tapered roller bearings with respect to the needle roller bearing work speed is higher
Tapered roller bearings are generally selected high-quality bearing steel and special steel and thin-walled needle roller bearings are made of steel stamping
In short, these two types of bearings are not the same type of bearings, there are too many different, must be compared to some really far
Needle roller bearings are fine and long needle and cage composition. Cylindrical Roller Bearings. Is composed of cylinders and rollers. The column is thicker than the needle, also known as coarse needle.
