- Product Definition and Uses
- Round rubber bellow for shaft and screw protection are protective components specifically designed for axial transmission elements. They are primarily used to protect screws, hydraulic cylinders, pneumatic cylinders, etc., from oil, water, dust, or foreign objects entering the transmission mechanism during reciprocating motion, thus preventing impact on operational accuracy and service life.
- These round bellows are also commonly used for fluid level control and protection in electrical discharge machining (EDM) machines, as well as for full-stroke protection of ultra-long-stroke screws. To meet rapid delivery requirements, standardized size charts are provided for quick selection of standard specifications including inner diameter, outer diameter, flange type, and flange configuration; customized designs based on the application environment are also supported. Commonly used materials comply with EU RoHS regulations.
- In what situations is it appropriate to use a round rubber bellow?
- In practical equipment design and maintenance applications, the round bellows are particularly suitable for the following conditions:
- 1. The transmission element is an axial linear reciprocating motion.
- 2. It is necessary to prevent oil, water, or dust from entering the screw or cylinder.
- 3. The screw stroke is relatively long, requiring full-stroke protection.
- 4. The equipment needs to balance oil resistance, heat resistance, and sealing performance.
- 5. It is desirable to have fast delivery through standard specifications or to have custom sizes made to order.
- Compared to cloth or metal covers, round rubber bellows have significant advantages in sealing performance, elasticity, and ease of installation.
