Description

DEDE Seal Co., Ltd. is one of the most reliable manufacturers and suppliers of radial shaft oil seal in China. If you're going to buy bulk radial shaft oil seal made in China, welcome to get pricelist from our factory. All customized seals are with high quality and competitive price.

 

This radial shaft oil seal adopts metal skeleton and elastic rubber integrated molding, equipped with built-in tension spring to keep consistent lip pressure against the shaft. Standardized dimensional precision realizes close assembly fit, balancing leak-proof and dust-proof performance for both light and heavy-duty rotary equipment.

 

Selection Tips

 

 

Multiple working parameters should be confirmed before ordering to pick the matching radial shaft seal: shaft diameter, rotation speed, lubricant medium, operating temperature and ambient environment. Proper material matching is the key to long-term sealing effect and longer service life.

 

Material Options

 

NBR Nitrile Rubber

Compatible with mineral oil, grease and most general industrial machinery, cost-effective for normal temperature working conditions.

FKM Fluoroelastomer

Applied to high-temperature environments and equipment exposed to corrosive chemical media, with excellent heat and chemical resistance. Custom rubber formulas are available for special working conditions.

 

Typical Applications

 

 

Radial shaft oil seals fit all common rotary transmission machinery:

● Industrial gearboxes & speed reducers

● AC/DC electric motors

● Hydraulic pumps, water pumps and air compressors

● Conveyor transmission equipment

● All kinds of general industrial transmission systems

FAQ

 

 

Q1: What is the difference between radial shaft oil seal and ordinary rotary oil seal?

A: The core difference lies in the sealing principle and application focus. the seal adopts uniform radial clamping sealing with better coaxiality and shaft follow-up performance, adapting to working conditions with slight shaft deviation. Ordinary rotary oil seals have single performance and poor fault tolerance, only suitable for stable and error-free operation scenarios.

Q2: What scenarios is EPDM radial seal suitable for?

A: EPDM features excellent water resistance, steam resistance and weather resistance. It is specially designed for water-containing media, humid environments and low-temperature damp working conditions, widely used in water treatment equipment and humid electromechanical equipment.

Q3: Can radial shaft oil seals adapt to slightly eccentric shafts?

A: Yes. The optimized elastic lip and spring compensation structure enables the seal to adapt to slight shaft eccentricity and runout during operation, avoiding leakage failure caused by shaft deviation, with higher working condition adaptability.
