Solid Lubrication Bearing for Elevator
MTWB solid lubrication bearings for elevators are designed for elevator OEMs, manufacturers and maintenance applications where conventional grease lubrication is difficult, impractical or uneconomical. These self-lubricating elevator bearings use embedded lubricant technology to provide reliable performance under demanding operating conditions, including high loads, low speeds, dust, humidity and elevated temperatures.
By reducing or eliminating the need for regular re-lubrication, MTWB solid lubrication bearings can help elevator equipment manufacturers reduce maintenance requirements, minimize lubricant leakage and improve long-term operating reliability. Customized bearing dimensions, lubrication types and application-specific configurations are available for elevator systems and related equipment.
Note: Custom specifications and dimensions are available upon request for specific elevator applications.
With polymer matrix adsorption saturated lubricant technology, the lubricant seamlessly adheres to the raceway and rolling elements without the need for an external oil supply system—re-greasing is completely eliminated.The embedded sealing design effectively prevents invasion of pollutants, improves water flushing resistance by 80%, and significantly reduces the risk of downtime caused by lubrication failure.
Solid lubricant content is 2–4 times higher than traditional lubricants, extending bearing service life by more than 3 times and significantly reducing the frequency of spare parts replacement.
The solid lubricant remains in close contact with the raceway and rollers, almost filling the entire bearing. The remaining space within the body effectively prevents pollutants from entering the bearing, protecting it from contamination-related failures.
Lubricating oil is stored in the micropores inside the polymer based on surface tension. During operation, oil transfers to the material surface under capillary action; when operation stops, oil is reabsorbed into the polymer for “storage,” preventing environmental pollution caused by lubricant leakage.
Suitable for high ambient temperatures (up to 200°C), high humidity, dusty conditions, and chemical corrosion environments.
MTWB provides self-lubricating elevator bearing solutions for OEM manufacturers and industrial equipment suppliers seeking reduced maintenance and reliable long-term performance. By using embedded lubrication technology, these bearings are designed to maintain effective lubrication during operation without relying on frequent external grease replenishment.
The solution can be considered for elevator traction systems, guide mechanisms, door operator systems and other applications where maintenance access is limited or lubricant contamination must be controlled. Bearing dimensions, lubricant formulation and performance requirements can be evaluated according to specific equipment designs and operating conditions.
MTWB Solid Lubrication Bearings are ideal for a wide range of elevator applications, including:
◆Elevator guide shoes – Providing smooth, maintenance-free sliding along guide rails
◆Traction machine bearings – Withstanding high loads and continuous operation
◆Door operator mechanisms – Ensuring reliable, quiet operation
◆Counterweight roller guides – Reducing friction and wear
◆Gearless elevator motors – Eliminating the need for periodic re-lubrication
◆Escalator drive systems – Performing reliably in demanding environments
The self-lubricating properties make these bearings particularly suitable for enclosed elevator shafts where cleanliness is a priority and grease contamination must be avoided.The solid lubricant fills the surface of guide rails and bearing surfaces, improving smoothness and reducing the friction coefficient during operation.
Performance data is based on MTWB internal testing under specified laboratory conditions. Actual service life may vary depending on load, speed, temperature, contamination, lubrication and operating environment.
A solid lubrication bearing for elevators is a bearing designed to operate with solid lubricants embedded or incorporated into the bearing structure. It is suitable for elevator and vertical transportation applications where conventional grease lubrication may be difficult, inconvenient or require frequent maintenance. By providing continuous lubrication during operation, solid lubrication bearings can help reduce lubricant replenishment requirements and support reliable performance under demanding operating conditions.
A self-lubricating elevator bearing uses a solid lubricant integrated into the bearing material or lubrication system. During operation, a controlled amount of lubricant is gradually released onto the sliding or rolling contact surfaces, forming a lubricating film that helps reduce friction and wear. This design can minimize the need for regular external lubrication and is particularly useful in elevator mechanisms where maintenance access is limited.
Solid lubrication bearings can significantly reduce routine lubrication requirements and may be described as maintenance-free from a lubrication perspective when properly selected and operated within their specified conditions. However, the complete elevator system still requires regular inspection and preventive maintenance in accordance with equipment manufacturer recommendations and applicable safety regulations. Actual bearing service life depends on factors such as load, speed, temperature, contamination, installation and operating conditions.
Solid lubrication bearings for elevators offer several potential advantages, including reduced lubrication and maintenance requirements, lower risk of grease leakage, reliable operation in applications with limited maintenance access and improved resistance to certain operating environments. They can also help reduce lubricant contamination and support longer maintenance intervals. The actual performance benefits depend on the bearing design, solid lubricant type and specific elevator operating conditions.
Yes. MTWB can provide customized solid lubrication bearing solutions for elevator OEMs, equipment manufacturers and industrial customers. Depending on the application requirements, customization may include bearing dimensions, materials, solid lubricant formulation, internal design, load capacity, operating temperature range and other application-specific specifications. Customers can provide drawings, technical data or operating conditions for MTWB engineering evaluation and customized bearing development.
Solid lubrication bearings can be considered for various elevator and vertical transportation applications, including elevator guide mechanisms, traction machine systems, elevator door operator mechanisms, counterweight guide systems and other components requiring reliable low-maintenance bearing performance. They may also be used in related equipment such as escalators and industrial lifting systems, depending on the specific load, speed, temperature and environmental conditions.
Yes, certain solid lubrication bearing designs can be suitable for dusty, humid or other challenging operating environments where conventional grease lubrication may be difficult to maintain. The suitability depends on the bearing material, sealing or protective configuration, solid lubricant type and actual environmental conditions. For applications exposed to high humidity, dust, water or contamination, MTWB can evaluate the operating conditions and recommend a suitable solid lubrication bearing configuration.
