JDB-5 product description
JDB-5 steel-based lubricated embedded bearing is a reinforced product with high compression resistance. It can discharge lubricating particles during operation, so that a diaphragm is formed between the shaft and the sleeve, which is more resistant to single oil lubrication. The advantage of occlusal is especially suitable for the support part of the hoisting machinery. For example: rolling field machine support, crane support, but not suitable for use in water or acid and alkali occasions.
