Eliche Radice RMTA Axial Propeller Shaft Seals with Bronze or Resin Bearing Ø25–40 mm
Eliche Radice RMTA Axial Propeller Shaft Seals are designed for sealing marine propeller shafts and replacing traditional gland packing arrangements. The seals feature an elastomeric body made from flame-retardant CR rubber, with separate connections for water and grease lubrication.
The RMTA range includes eight configurations for propeller shaft diameters from 25 to 40 mm, available with bronze or resin bearing connections. The two versions have different mounting diameters to suit the corresponding shaft installation.
Flame-Retardant CR Rubber Construction
The RMTA seal body is manufactured from flame-retardant CR elastomeric rubber with characteristics suited to marine shaft sealing applications.
The material is designed to withstand contact with oil and grease while providing low-friction sealing performance.
Operating Temperature Range
Eliche Radice specifies an operating temperature range from -10°C to +80°C for the RMTA axial seals.
Alternative to Traditional Gland Packing
The RMTA axial shaft seal is designed to replace conventional packing used in marine propeller shaft sealing assemblies.
The elastomeric sealing construction provides a dedicated sealing solution for rotating marine propeller shafts.
Water and Grease Lubrication Connections
The RMTA seal features separate connections identified in the manufacturer's technical drawing:
- Water Inlet: Connection for water lubrication.
- Grease Inlet: Connection for grease application.
These connections form part of the shaft seal's lubrication arrangement.
Bronze and Resin Bearing Versions
The range includes two mounting configurations:
- Bronze Bearing Version: Four models with mounting diameters P from 39 to 54 mm.
- Resin Bearing Version: Four models with mounting diameters P from 42 to 60 mm.
Both versions are available for shaft diameters of 25, 30, 35 and 40 mm.
