The radial ball bearing is a general-purpose depiction; it can accept different loads in high-speed motion. This type of rolling bearing consists of a complete set of fine balls and holding frames as well as inner and outer rings. There is a deep in the standard radial ball bearing. The groove layout is capable of accepting radial loads from a free direction and a small axial load. The radial ball bearing with the highest load capacity is mainly subjected to radial load. This type of tumbling bearing has various sizes to choose from. Different sealing equipment can protect the internal components of the rolling bearing; and can retain lubricating grease.
The use of large-scale radial ball bearings is widely used in general industry; automotive occupation; agriculture; chemical industry and household appliances occupation.
How to determine the normal spherical ball bearing; the inner and outer ring raceways should have no shedding and severe wear scars; and a circular arc with bright light, all the balls should be round; the surface is free of mottle, crack and Shedding, insisting that the frame is not slack, not broken, not worn. When using one hand inner ring; the other hand agilely pushes the outer ring to rotate; the demand rotates smoothly; only the ball is heard on the raceway.
The radial ball bearing with normal skill condition; the inner and outer ring raceways should have no falling off and severe wear marks; and a circular arc groove with bright light, all the balls should adhere to the round shape; the surface is free from mottle, crack and fall off, Adhere to the frame is not slack, not broken, not worn. When using a hand-held inner ring; the other hand agilely pushes the outer ring to rotate; the demand rotates smoothly; only the fine movement of the ball rolling on the raceway is heard; no oscillation , should be gradually slowed down when it stops; there is no backward appearance after stopping.
Normal centripetal ball bearing; the gap between the inner and outer rings and the roll body is 0. 005-0. 010mm; when the inner and outer rings are swayed in the radial direction; the gap should be felt. The used bearing; Hold the inner ring and shake it a few times in the axial direction; when the outer ring and the ball have significant movement; clarify that the cooperation gap exceeds 0.03mm; it should not be used continuously.
The NSK bearing with normal skill condition; the inner and outer ring raceways should have no shedding and severe wear scars; and a circular arc with bright light, all the balls should adhere to the circle; the surface is free from mottle, crack and shedding. Adhere to the frame is not slack, not broken, not worn. When using a hand-held inner ring; the other hand agilely pushes the outer ring to rotate; the demand rotates smoothly; only the fine movement of the ball rolling on the raceway is heard; Oscillation, it should be gradually decelerated when it stops; there is no backward appearance after stopping; normal centripetal ball bearing; the gap between the inner and outer rings and the rolling body is 0. 005-0. 010mm; when the inner and outer rings are swayed in the radial direction Should feel the gapless. NSK bearing used; can hold the inner ring by hand to shake a few times in the axial direction; when the outer ring and the ball have obvious movement; clarify that the cooperation gap exceeds 0. 03mm; should not continue use.
