Expansion Sleeve

Through the action of high strength tensile bolt, the inner ring and the shaft, the outer ring and the hub between the great holding force, in order to achieve the key and shaft connection. When the load is borne, the torque, axial force or the composite load of the two is transmitted by the combined pressure of the expansion sleeve and the parts and the shaft and the accompanying friction force.

1. The use of expansion sleeve makes the manufacture and installation of host parts simple. The machining of the shaft and hole for installing the expansion sleeve does not require the same high manufacturing tolerances as the interference fit. When INSTALLING THE expansion sleeve, THERE is no need to heat, cool or pressurize the equipment, just tighten the bolt according to the required torque. The hub can be conveniently adjusted to the desired position on the shaft. Expansion sleeves can also be used to join poorly soldered parts.

2. Long service life and high strength. The expansion sleeve is driven by friction, which has no keyway to weaken the connected parts, no relative movement, and no wear and tear during work.

3. Expansion sleeve in overload, will lose the connection, can protect the equipment from damage.

4. Expansion sleeve connection can bear multiple loads, its structure can be made into a variety of patterns. According to the size of the installation load, you can also use multiple expansion sleeve in series.
