Merchandise Description

Data

Shaft sleeve refers to the sleeve on the propeller shaft or stern shaft. The bearing is a component which can repair and decrease the friction coefficient of load
during the mechanical transmission.

The identical point in between the sleeve and the bearing is that both bear the load of the shaft.
The big difference among the 2 is that the sleeve is of the total framework, and the relative movement among the shaft and the sleeve is the
rotation the bearing is break up kind, and the rotation is the relative motion of the inner and outer rings of the bearing. But in essence, the sleeve is actually a sort of sliding bearing.

The bearing bush is equivalent to the outer ring of the sliding bearing. The sleeve is integral and the relative shaft is transferring. Some of the bearing shells are break up and the relative shaft is rotating.

In LEGO mindstores and biotrans rosys series robotic elements, the shaft sleeve refers to the LEGO standard axle holder in silver grey, which is divided into 2 kinds: total shaft sleeve and 1 / 2 shaft sleeve.

MAINTENANCE 

Typical fault causes
