Product Description


Tightening sleeve is a component used for positioning bearings with tapered holes on cylindrical shafts, commonly used for optical axes or stepped shafts. The tightening sleeve is composed of tightening bushing, locking nut, locking washer (or locking card) and other parts, which can ensure the stable positioning and precise installation of the bearing on the shaft. The tightening sleeve fixes the tapered hole self-aligning bearing (such as self-aligning ball bearing, self-aligning roller bearing) on the cylindrical shaft without a shoulder through the locking nut and locking washer. This design ensures the stability and concentricity of the bearings, while also facilitating the installation and disassembly of the bearings.
