Cylindrical roller bearings are attributed to the fine bearing; the rim guide of the finely-rolled roller post ring; consists of the cage, the roller and the guide collar; it can be separated from the other bearing ring; it can be attributed to the separate bearing. The bearing device and disassembly are more convenient; especially when the inner and outer rings are required to cooperate with the shaft and the shell, the bearing is usually only used for real-loading with the radial load gun; as long as the inside and outside Single-row bearings with ribs on the rim can be compared with other constant axial loads or large intermittent axial loads, as well as other dimensions of the same dimensions; such bearings have high loads; bottom noise and high speed characteristics Very suitable for all kinds of fine machinery and mining mill machinery. But for the shafts that cooperate with such bearings; the rolling parts and other related parts require fine processing.
Needle roller bearings (NK, NKS, RNA49, RNA48, NKL, NKLS, NA49, NA48, RNA69, NA69, RNA49... RS, RNA49. 2RS, NA49. RS, NA49. 2RS, RNAO, NAO) Layout Compact, radial scale. Testicular naphthalene sees 螅 螅 惺 缶 缶 . .. This type of bearing has a variety of layout and scale series; assembled G2 grade needle; group batch diameter variation within 2um; Outside the needle bearing; high-strength cage is used; the needle parallel axis can be correctly guided.
The layout is different; the type is different; the direction of the receiving force is different; the rotating speed is different; the load is different; the raw materials are different; the occasions used are different, etc. The difference is that the rolling roller of the tapered roller bearing is a tapered roller. The rolling body of the needle bearing is a needle roller.
The above difference in the resolution determines that the layout of the tapered roller bearing is larger than that of the needle bearing; the tapered roller can accept the axial force in addition to the radial force; and the needle roller bearing can only accept the radial force.
Tapered roller bearings are divided into single columns and multiple columns; do not use different environments and occasions.
The tapered roller bearing has a higher operating speed than the needle bearing.
Tapered roller bearings are usually made of high-quality bearing steel and special steel, while thin-walled needle bearings are stamped from steel.
Totally; these two types of bearings are not the same type of bearing; there are too many different; to be more realistic, some reluctant needle bearings are composed of thin and long needles and cages. Cylindrical roller bearings. Cylindrical And the roller is composed. The column is thicker than the needle roller; also called the coarse needle roller.

Specifications

Here are all METABO power tools and the designated carbon brushes,motor brushes, electric brushes, motor brushes, electric motor brushes or simply brushes.

For each power tool, there are usually two carbon brushes to choose from: With automatic stop and without automatic stop. Carbon brushes with automatic stop have a spring through the length of the carbon brush. When the carbon brush wears out, the spring gets released, the current to the carbon brush gets interrupted and your power tools switches off at once. The advantage: No additional wear and tear to your power tool. Carbon brushes without automatic stop do not stop functioning at once, but performance of your power tool will detoriate rapidly. Although handy as a warning sign, this usually isn't very beneficial to your power tool.

If you can't find your METABO power tool here, please contact us: Most likely we can help!
