2204 Bearing
The 2204 bearing is a self-aligning ball bearing with an inner diameter of 20 mm , an outer diameter of 47 mm, a width of 18 mm. It typically uses P4 grade precision tolerances and Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Self-aligning Ball Bearing
Model:2204
Size: 20mm*47mm*18mm
Material:Chrome steel
Self-aligning Ball Bearing 2204 is recommended when alignment of the shaft and housing is difficult and the shaft may flex.
The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center.
Pressed steel cages are usually used.
It has two rows of balls and a common concave sphered raceway in the outer ring. The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing.
It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected.
Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds. Self-aligning ball bearings are available in several designs.
Since the contact angle is small, the axial load capacity is low. The permissible dynamic misalignment is approximately 0.07 to 0.12 radian (4 to 7 degrees) under normal loads.
Except this,we also offer the following bearings:
Deep Groove Ball Bearings, Tapered Roller Bearings, Angular-contact Ball Bearings, Thrust Ball Bearings, Insert Ball Bearings and Needle Bearings are our main products.
We have many stocks. A promotion is being made these days. Maybe it\'s a good chance for u.
