Part Two: Are You Familiar with The Material of Sliding Gate Wheel?

In the last issue, we deeply discussed the importance of the LSV series bracket and roller material of the sliding door bottom wheel to the entire pulley system. In this issue, we will continue to discuss in depth the core role of bearings in pulley systems and the impact of material selection.

Bearings play a vital role in sliding gate pulley systems. High-quality bearings can not only significantly increase the load-bearing capacity, but also enhance the smoothness and overall durability of the sliding door, directly affecting the service life and performance of the pulleys.

Choose the right bearing material:

There are many types of bearing materials on the market, including carbon steel, bearing steel, stainless steel, ceramics, plastics, alloy steel, bronze and aluminum-based composite materials. In view of the characteristics of sliding door pulleys, we focus on bearings made of carbon steel and bearing steel.

1. Carbon steel bearings: low cost, suitable for light loads, low speeds or temporary applications, but their wear resistance and fatigue resistance are relatively weak.

2. Bearing steel bearings: usually refers to high-carbon chromium bearing steel, such as GCr15, which is known for its high hardness, wear resistance and fatigue resistance, and is very suitable for high-speed and heavy-load working environments.

Considering the operating speed and usage environment of the sliding gate, we recommend the use of bearings made of bearing steel. Bearings made of this material can withstand harsh outdoor conditions such as humidity, temperature fluctuations and pH changes, while handling the challenges posed by the weight of the gate.

Open company’s professional options:

Open Company, as a pulley manufacturer with 25 years of production experience, always insists on using bearing steel. Although the cost is higher, it ensures the excellent quality of the products and a long warranty period of up to 5 years.

Key factors in bearing performance:

Choosing the right bearing material is only the first step. Bearing clearance, groove accuracy, and lubricant usage are equally critical, and together they determine the performance of the bearing and even the entire pulley system.

Future discussion directions:

In the following discussion, we will provide an in-depth analysis of bearing clearance, groove accuracy, and lubricant selection to discuss how to develop the best solution for a sliding door pulley system.

Industry exchange invitation:

We sincerely invite colleagues in the industry to provide valuable opinions and jointly communicate and make progress. By sharing 25 years of manufacturing experience, we hope to bring value to the industry and drive technological development.
