Industriella oljetätningar (radiella axeltätningar) för roterande utrustning

Oil Seals supplied by Wonzh are precision-engineered radial shaft seals designed to retain lubricants, prevent fluid leakage, and block the ingress of dust, dirt, and contaminants in rotating machinery. Commonly installed on shafts in gearboxes, motors, pumps, and industrial equipment, these seals play a critical role in extending bearing life and improving system reliability.

Manufactured from high-quality elastomers such as NBR, FKM (Viton), ACM, and silicone, and reinforced with metal casings and spring elements, Wonzh oil seals provide excellent wear resistance, thermal stability, and sealing performance under dynamic conditions. Advanced molding and strict dimensional control ensure consistent lip contact, low friction, and long service life.

As an experienced industrial sealing supplier, Wonzh offers standard metric and inch oil seals as well as customized designs for special shaft sizes, operating conditions, and media compatibility. Our engineering team supports material selection, seal profile optimization, and application guidance based on real-world performance requirements.

Vanliga frågor och svar (FAQ)

Q1: What is an oil seal used for?

An oil seal prevents lubricant leakage from rotating shafts while keeping dust, dirt, and contaminants out of the system.

Q2: What is the difference between single-lip and double-lip seals?

• Single lip: Best for lubricant retention.

• Double lip: Provides additional protection against dust and contaminants.

Q3: Can oil seals handle high temperatures?

Yes. With FKM (Viton) material, oil seals can operate reliably at temperatures up to around 200°C, depending on application.

Q4: Are custom sizes available?

Yes. We can manufacture oil seals in custom shaft and housing dimensions based on your requirements.

Q5: Do you support industry standards?

Yes. Our oil seals comply with DIN 3760 and equivalent international standards.
