Agricultural Bearing 200 Series

Agricultural Bearing 200 Series
ISUTAMI 200 series agricultural bearing series is a kind of special agricultural bearing. Its appearance is similar to that of a disc harrow bearing or a hex bore agricultural bearing. The inner ring of this bearing is round and suitable for engagement with a round shaft. The main body of the 200 series bearing is a deep groove ball bearing. Its material is chrome steel GCR15, which is a sort of fully hardened steel. This material has good pressure bearing performance in practical application. The retainer of the steel ball in the bearing is made of steel or nylon. The 200 series bearing has a dust-proof ring structure, which is indicated by R. It has a good dust-proof function and is lubricated with filling grease, which makes the whole bearing with low noise and long service life. This series of bearings uses inches as a unit.

Agricultural Bearing 200 Series Feature

ISUTAMI 200 series agricultural bearings are divided into 4 types. The outer rings of type 1, type 2 and type 4 are in the middle of the bearing, and the inner rings with convex are at both sides of the bearing, especially, the inner ring convex of type 3 is only at one side of the bearing. The inner diameter (d) of this series ranges from 0.6253'' to 1.5748'', the dimensional tolerance is generally 0.0003'', 0.0005'' or 0.005''; the length of the inner ring (Be) ranges from 0.551'' to 1.063' ', and the corresponding tolerance is 0.0005''. The diameter of the outer ring (D) ranges from 1.5748'' to 3.1496'' with a corresponding tolerance of 0.0005''; the length of the outer ring (Bi) ranges from 0.4724'' to 0.827'' with a corresponding tolerance of 0.005''. The inner ring length of the bearing is considered to be the length of the entire bearing. The dynamic load rating of 200 agricultural bearings ranges from 2160kgf to 7340 kgf, and the static load rating ranges from 889kgf to 3650 kgf. In addition, the basic 203KRR2 bearing has a Gothic outer ring as well as a double lip seal. The rated dynamic load with the same specification is 1.5-2.5 times of the rated static load. In general, the rated load of the 200 series bearings is much smaller than that of the disc harrow bearings, and is generally applied to low speed and moderate loading work.

Agricultural machinery requires better sealing to prevent contamination such as dust, misalignment and economical installation of shafts and housings. ISUTAMI provides conventional 200 agricultural machinery bearings, which are widely used in agricultural machinery and agricultural conveyors, and are an indispensable core component. 100% of these bearings are quality checked. We can also provide more other special size products according to the specific needs of customers.
