Roller
Using 304 stainless steel bearings and polymer muffler groove rails, we can achieve 100,000 trouble-free operation under the limit load of 25kg. Specially designed for heavy-duty pull-up windows and curved curtain walls, verified by the Nordic extreme cold (-30℃) to the Middle East wind and sand (50℃) environment, so that each door and window slides as smooth and silent as cloud rails.
