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

End Cap Cover Oil Seal is specially designed for the end cap position of enclosed transmission equipment such as gear reducers. After standardized installation, it can firmly seal the gap between the end cap and box body to stop oil leakage, and isolate external dust, muddy water and humid air from invading the gearbox cavity. Well-matched and correctly installed seals effectively reduce abrasion of gears and bearings, delay seal aging, and greatly lengthen the cycle of equipment overhaul and maintenance.

Installation Recommendations

Pre-installation inspection

Check the inner hole of the housing and mating shaft to remove burrs, scratches, metal debris and dirt.

Lubrication treatment

Coat a thin uniform layer of compatible lubricant on the sealing lip to reduce assembly friction.

Standard pressing

Use matched professional installation tools to press the seal into the bore evenly and horizontally.

Forbidden operation

Never knock the metal skeleton shell directly with a hammer; shell deformation will cause permanent sealing failure.

Typical Applications

All types of gear reducers and speed change gearboxes

Complete sets of industrial power transmission systems

Agricultural tractors, harvesters and farm transmission machinery

Belt, roller and chain conveyor equipment

Vehicle and industrial power drive units

FAQ

Q1: What is the difference between EC and EG end cover oil seals?

A: They differ in structure and application scenarios. The EC model adopts a lip-free flat full-coverage structure, focusing on pure static high-tightness blocking with zero friction loss. The EG model is a lip cup type suitable for slight dynamic conditions. EC is more suitable for pure static port sealing of gearboxes and bearing housings with higher stability.

Q2: Is sealant required for auxiliary sealing of this End Cap Cover Oil Seal?

A: No sealant is required for standard working conditions. Precise interference press fit realizes zero-leakage sealing, simplifying installation and avoiding equipment blockage caused by aging sealant residues. Auxiliary reinforcement is only needed for extreme negative pressure conditions.

Q3: Will thermal expansion and contraction cause leakage?

A: No. The material has excellent thermal deformation compensation capability. Cooperating with the rigid integral frame, it adapts to minor shell thermal changes and assembly tolerances, maintaining tight fitting without gap leakage under temperature fluctuation.
