SDB

The acronym SDB in a pneumatic context most commonly refers to mounting accessories for air cylinders or occasionally to a type of seal/scraper. Since "SDB" is a model series designation used by various manufacturers, its specific meaning can vary, but here are the two most common uses in pneumatics: 1. SDB Bracket (Air Cylinder Mounting) This is the most frequent use. The SDB Bracket is a type of mounting stand or bracket used to secure small-to-medium size pneumatic air cylinders (like the MAL or MA series) to a machine or frame. Function: It provides a stable, fixed point for the cylinder body, allowing the piston rod to perform its linear motion accurately. Design: These brackets typically conform to certain ISO standards for cylinder mounting accessories, ensuring compatibility across different brands. 2. SDB Scraper (Seal) SDB can also stand for a series of scrapers or dust seals used on the piston rods of pneumatic cylinders. Function: A scraper's purpose is to prevent dust, dirt, moisture, and other foreign particles from entering the cylinder bore. This protects the internal seals and bearings, significantly extending the life of the pneumatic cylinder. Material: Often made of materials like Nitrile Rubber (NBR).
