Bearings for Lifts
It should be noted that grease must be added to the bearing during use, so that the bearing can function better. However, adding too much grease will also increase the running resistance, which has some influence on the speed.
Escalators
There are well over 100 bearings in a typical escalator, with two bearings used to support each stair and several contained in the drive motor, transmission and handrail assemblies. The majority of these bearings are deep groove ball bearings operating at low speeds and moderate loads.
As the majority of escalators are installed in controlled indoor environments, contamination and temperature are generally not big concerns. Bearings in escalators are, however, required to be quiet running, highly reliable and low maintenance. ZZ supplies bearings meeting all of these criteria. In addition, ZZ can provide products and systems that allow improved control and ease of maintenance of the escalator.
Elevators
Another type of popular lift is elevators which can be classified as either traction or hydraulic types. In traction elevators, cables and electric motors are used to raise and lower the car. In hydraulic elevators, a hydraulic cylinder is used to control the car’s ascent and descent. Both types of elevators use multiple bearing types, and safety and reliability are the primary concerns in bearing selection. The modern elevators are also required to be very quiet, thus the bearings must generate as little noise as possible.
