Rhein Lighting has provided a line of 2x4 flat Led Panel Light. The flat panel light has No LGP, back-lit design, and the lens is made of PMMA and will not yellowing over time, which is much more bright and more durable than edge-lit light panel. Take 2x2 led light drop ceiling for example, it can replace the equivalent of 420W fluorescent tubes, saving you up to 80% in energy consumption.
The led ceiling panel light provides long-life and uniform illumination, in addition to being equipped with a 0-10V dimmable driver. These led light panels are ETL, DLC, CE, ROHS approved, and it has a 5 years limited warranty.
Rhein Lighting is a specialized in the design and manufacture of led panel downlight, led slim down light, backlit led panel light, led rope light, Led Strip Light, led plant light and led grow light etc.

The sealing of a slewing bearing plays a crucial role in maintaining its performance and longevity. On one hand, it prevents the leakage of the lubricating grease that is filled inside the bearing, ensuring proper lubrication. On the other hand, it acts as a barrier against external contaminants such as dust, dirt, and moisture, which can significantly affect the bearing's operation and reduce its lifespan.
Slewing bearings are typically used in heavy-duty applications with low rotational speeds. Due to these conditions, the sealing system must be both reliable and durable. There are two primary sealing methods commonly used: rubber seals and labyrinth seals.
Rubber sealing systems are widely used due to their simplicity in design and compact structure. They provide effective protection against contamination and are relatively easy to install. However, they may wear out over time, especially under harsh conditions. Labyrinth seals, on the other hand, offer a more robust solution by using a series of intricate grooves or channels to block the entry of foreign particles without direct contact, making them ideal for high-load and high-temperature environments.
Choosing the right sealing method depends on the specific application, environmental conditions, and maintenance requirements. Proper sealing not only enhances the bearing’s performance but also reduces downtime and maintenance costs.
