6001LLU Deep Groove Ball Bearing Details

This 6001LLU bearing is a Shielded Deep Groove Radial Ball Bearing with a standard radial internal clearance The bearing's dimensions are 12x28x8mm.

Working principle
  6001LLU mainly bear radial loads, and can also bear both radial and axial loads simultaneously. When it only bears radial loads, the contact angle is zero. When 6001LLU have a large radial clearance, they have the performance of angular contact bearings and can withstand large axial loads. The friction coefficient of deep groove ball bearings is very small and the maximum speed is also high.
6001LLU characteristics
Deep groove ball bearings-6001LLU are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to withstand radial loads, but when the radial clearance of the bearing is increased, it has a certain degree of angular contact ball bearing performance and can withstand combined radial and axial loads. When the speed is high and thrust ball bearings are not suitable, they can also be used to withstand pure axial loads. Compared with other types of bearings with the same specifications and dimensions as deep groove ball bearings, this type of bearing has a lower friction coefficient and a higher limit speed. But it is not resistant to impact and not suitable for bearing heavy loads.

Installation method of 6001LLU
Press fit: The inner ring of the bearing is tightly fitted with the shaft. When the outer ring and bearing seat hole are loosely matched, a press can be used to press the bearing onto the shaft first, and then the shaft and bearing can be installed into the bearing seat hole together. During press fitting, a soft metal assembly sleeve is placed on the inner ring end face of the bearing, and the outer ring of the bearing is tightly fitted with the bearing seat hole; When the inner ring is loosely matched with the shaft, the bearing can be pressed into the bearing seat hole first. At this point, the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole If the bearing ring is tightly fitted with the shaft and seat hole, both the inner and outer rings of the installation chamber should be pressed into the shaft and seat hole at the same time, and the structure of the assembly sleeve should be able to simultaneously press the end faces of the bearing inner and outer rings.
