Elevator Door Hanging Wheel 45*26*6000 WITTUR CN0454 – Nanjing Zhuye Elevatorparts
The elevator door system is the direct interface between passengers and the elevator, and the door hanging wheel is a core transmission component that ensures the smooth and quiet operation of the elevator door. The Elevator Door Hanging Wheel 45*26*6000 WITTUR CN0454 provided by Nanjing Zhuye Elevatorparts is a high-precision replacement part tailored for WITTUR elevator door systems, with dimensions 45mm (outer diameter) * 26mm (width) * 6000 (bearing specification). It is perfectly compatible with WITTUR CN0454 series elevator door mechanisms and is also widely applicable to modified elevator door systems that match the dimensions. Crafted with high-strength aluminum alloy rims, high-precision 6000 series bearings, and wear-resistant rubber sleeves, this door hanging wheel meets international elevator safety standards (EN 81-20, GB 7588) and has become a trusted choice for global elevator maintenance teams and property management companies.
Nanjing Zhuye Elevatorparts adheres to the core philosophy of “Smooth Transmission, Durable Operation” and implements strict quality control for the Elevator Door Hanging Wheel 45*26*6000 WITTUR CN0454. Each unit undergoes rigorous testing, including load-bearing capacity verification, wear resistance testing, noise level detection, and rotation flexibility assessment. The wheel rim is made of high-strength aluminum alloy, which is lightweight yet has excellent load-bearing performance (supporting a maximum load of 150kg per wheel). The built-in 6000 series deep groove ball bearing is filled with high-temperature resistant grease, ensuring smooth rotation with a friction coefficient ≤ 0.02. The surface is equipped with a high-wear rubber sleeve that effectively reduces noise (operation noise ≤ 45dB) and avoids direct friction between metal and the guide rail. The integrated stamping and molding process enhances the structural stability of the wheel, preventing deformation during long-term operation, making it suitable for the high-frequency opening and closing working environment of elevator doors.
Usage Guide for Elevator Door Hanging Wheel 45*26*6000 WITTUR CN0454
Correct installation, adjustment, and maintenance are crucial to maximizing the service life and operation stability of the Elevator Door Hanging Wheel 45*26*6000 WITTUR CN0454. Nanjing Zhuye Elevatorparts recommends that only certified elevator maintenance technicians perform related operations to avoid door system jamming or safety hazards caused by misoperation.
1. Pre-Installation Preparation
First, confirm that the elevator door system model matches the 45*26*6000 WITTUR CN0454 door hanging wheel (check the original wheel’s dimensions and bearing specification). Consult Nanjing Zhuye Elevatorparts’ technical team if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and the secondary power supply for the door system, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator landing doors. Use wooden wedges to fix the elevator door in a closed state to prevent accidental movement. Finally, prepare professional tools such as a socket wrench, screwdriver, caliper, lubricating grease, and a brush, and clean the door hanging rail and installation area to remove dust, debris, and old grease.
2. Installation & Adjustment
Loosen the fixing bolts of the door hanging bracket with a socket wrench, and gently lift the elevator door panel to unload the weight from the old hanging wheels. Remove the old hanging wheels from the bracket (note the installation direction of the wheels and bearings). Take the new 45*26*6000 WITTUR CN0454 door hanging wheel from Nanjing Zhuye Elevatorparts, apply an appropriate amount of high-temperature resistant lubricating grease to the bearing, and install it on the door hanging bracket in the correct direction. Tighten the fixing bolts (torque according to Nanjing Zhuye’s recommended value: 8-10 N·m) to ensure the wheel is firmly fixed without looseness. Adjust the height of the door hanging bracket to ensure the gap between the door hanging wheel and the guide rail is 0.5-1mm, and the door panel is parallel to the guide rail. After adjustment, manually push the door panel to check if it slides smoothly without jamming or deviation.
3. Post-Installation Testing & Daily Maintenance
Remove the wooden wedges fixing the door, restore the power supply, and test the automatic opening and closing function of the elevator door. Observe the door’s operation: it should open and close smoothly, with no abnormal noise or jamming, and the closing speed is uniform. After 50 times of opening and closing cycles, recheck the installation status of the hanging wheels and the tightness of the bolts. For daily maintenance, inspect the hanging wheels during weekly shaft patrols: check if the rubber sleeve has obvious wear (wear depth exceeding 2mm indicates the need for attention), if the bearing rotates flexibly without stuck or abnormal noise, and if the fixing bolts are loose. Clean the hanging wheels and guide rails with a brush every month, and apply new lubricating grease to the bearings every 3 months. For elevators in high-traffic areas, increase the inspection frequency.
Replacement Cycle of Elevator Door Hanging Wheel 45*26*6000 WITTUR CN0454
The replacement cycle of the door hanging wheel is closely related to the frequency of elevator use and the operating environment. Under normal circumstances (elevator daily operation 12-24 hours, daily door opening and closing times ≥ 1000, operating environment temperature -10℃ to 60℃, low dust), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 1.5-2 years. This cycle is determined based on long-term field operation data, wear resistance tests, and global user feedback, fully considering the wear of the rubber sleeve and the fatigue of the bearing.
For elevators in high-traffic areas (e.g., large shopping malls, airports with daily door opening and closing times ≥ 2000) or harsh environments (e.g., industrial sites with heavy dust, coastal areas with high humidity), the replacement cycle should be shortened to 8-12 months. High-frequency operation accelerates the wear of the rubber sleeve and bearing, while harsh environments cause corrosion of the bearing and aging of the rubber. For low-usage elevators (e.g., villa elevators, small office buildings with daily operation time < 8 hours) in stable environments, the cycle can be extended to 2-3 years, but only after inspection and confirmation by Nanjing Zhuye’s technicians that the wheel’s wear degree and bearing performance meet the safe operation standards.
Replace the door hanging wheel immediately if any of the following issues occur, regardless of its service life: The rubber sleeve is severely worn, cracked, or falls off; the bearing is stuck, rotates inflexibly, or makes abnormal noise (indicating internal damage); the wheel rim is deformed or cracked, affecting the fit with the guide rail; the door system jams, deviates, or makes loud noise during operation, and the fault is confirmed to be caused by the hanging wheel.
The Elevator Door Hanging Wheel 45*26*6000 WITTUR CN0454 from Nanjing Zhuye Elevatorparts integrates precision, durability, and compatibility, providing reliable transmission support for WITTUR and modified elevator door systems.
