The so-called rolling bearing clearance; is to fix a ferrule; the other ring has the maximum amount of motion in the radial or axial direction. The maximum amount of motion in the radial direction is called the radial clearance; the maximum amount of motion along the axial direction is called the axis. To the clearance. In general; the larger the radial clearance; the larger the axial clearance; and vice versa. According to the condition of the bearing; the clearance can be divided into the following three types: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. The clearance of the original clearance bearing device in the free condition. The original clearance is determined by the processing and installation of the manufacturer.
Second, the device clearance is also called the cooperative clearance; it is the clearance of the bearing and the shaft and the bearing seat device without working. Because of the interference device; or the inner ring is enlarged; or the outer ring is contracted. The arch dam and the dam are still snails.
Third, the clearance of the working clearance bearing in the working condition; the inner ring temperature rises the most during operation; the thermal expansion is the largest; the bearing clearance is reduced.

Some rolling bearings can't adjust the clearance; they can't be disassembled; there are six types of these bearings; 0000 to 5000, some rolling bearings can adjust the clearance; but they can't be disassembled; there are 6000 (angular touch bearing) and inner ring cone Hole type 1000, 2000 and 3000 rolling bearings; these types of rolling bearing device clearance; after adjustment will be more than the original clearance. 涣硗猓 涣硗猓 ┲岢 ┲岢 梢 梢 梢 梢 7000 7000 7000 7000 7000 Type (tapered roller bearing), 8000 type (thrust ball bearing) and 9000 type (thrust roller bearing); these three bearings do not have original clearance, 6000 and 7000 rolling bearings; radial clearance is adjusted . 嵯蛴 兑 嬷湫 嬷湫 嬷湫 嗳唬 嗳唬 8000 8000 8000 8000 and 9000 type rolling bearings; as long as the axial clearance has practical significance.
