160mm Hitachi Elevator Guide Rollers

Hitachi, a globally renowned conglomerate with a history steeped in innovation, has made significant strides in the elevator industry. One of the crucial components ensuring the smooth and efficient operation of their high-speed elevators is the guide rollers. Let’s delve deeper into the specifics of the high-speed Hitachi elevator guide rollers:

Functionality: At the core of their purpose, the guide rollers are responsible for keeping the elevator car aligned with the hoistway rails. In high-speed elevators, this function becomes even more vital as any misalignment can lead to severe complications given the speeds involved.
Design Precision: Considering the demands of high-speed travel, Hitachi has engineered their guide rollers to have minimal friction, ensuring a smooth journey from start to finish. The rollers glide seamlessly along the hoistway rails, providing an almost imperceptible ride even at great speeds.
Material Innovation: Hitachi’s commitment to excellence is reflected in the choice of materials for its guide rollers. Typically, these rollers are crafted from ultra-durable materials like polyurethane, which offers both resilience and superior vibration absorption. This choice ensures longevity and reduces the need for frequent replacements.
Safety: Given the high-speed nature of the elevators, safety is paramount. Hitachi’s guide rollers are designed to provide additional stability, ensuring the elevator car remains centrally aligned, minimizing sway and potential oscillations even when moving at top speeds.
Noise Reduction: One of the challenges with high-speed elevators is noise generation. Hitachi’s guide rollers, through their meticulous design and choice of materials, play a significant role in dampening noises, ensuring a quiet and comfortable ride for passengers.
Maintenance & Wear Indicators: Recognizing the importance of timely maintenance, some of Hitachi’s high-end guide rollers come equipped with wear indicators. These indicators allow for proactive maintenance, ensuring that rollers are replaced or adjusted well before any potential malfunction can occur.
Compatibility with Advanced Technologies: Hitachi, being at the forefront of technological integration, often pairs their guide rollers with advanced monitoring systems. These systems continuously monitor the performance of the guide rollers, providing real-time data that can be used for predictive maintenance and ensuring optimal performance at all times.
Environmental Considerations: In line with Hitachi’s commitment to sustainability, their guide rollers are designed to be environmentally friendly. The materials used are often recyclable, and the production processes aim to reduce the carbon footprint.

In essence, the high-speed Hitachi elevator guide rollers are a blend of precision engineering, innovative materials, and state-of-the-art technology. They ensure not only the comfort and safety of passengers but also exemplify Hitachi’s commitment to excellence and sustainability in the vertical transport sector.

Additional information

160mm elevator guide rolls	1. Unmarked size tolerances are in accordance with GB/T 1804-m. 2. Press C0.5 for unfilled chamfering. Press R1 for unfilled corners. 3. Rubber hardness: Shore A 74° ±5. (1) The measurement position of the rubber hardness is 4 points on the outer circumferential surface (rail contact surface), which should be measured after the outer circle is finally processed and formed. (2) The above-mentioned test quantity is 2 for each batch, even if 1 fails, all of them must be inspected. 4. Rubber bonding strength should be above 58.8N/cm. (1) After bonding, it works normally under the conditions of pushing force 1.47KN, speed 1m/s, and running time 10h. (2) The above test quantity is 2 per batch. 5. There should be no air bubbles, cracks, foreign matter incorporation and other harmful defects. (1) Appearance inspection is to visually inspect the surface and interior of the rubber to see if there are cracks, air bubbles, foreign matter mixed in, etc. (2) The above-mentioned test quantity is 2 per batch, even if one fails, all of them must be re-inspected. 6. After the outer circle is finally processed and formed, the end jump of the roller, the width of the roller and the outer diameter should be measured. (1) The end jump should be measured at the outermost diameter, and it is required to be below 0.06. (2) The number of measurements above is 5 for each batch. Even if one fails, all of them must be tested again. 7. The recovery rate of rubber is over 97%. (1) Use a sample of D29 and a thickness of 12.7, load it at 490N for 6 hours at room temperature, then remove the load, and measure the recovery rate after 30 seconds. 8. After machining the hub of sequence 2, the rubber of sequence 1 should be bonded by pressure forming. 9. Do not clamp the rubber part during processing. 10. The rubber material is NR (natural rubber).
