TSS type TRE and Stefa type CC

Type TRE are seals with a completely rubber covered outer diameter and a secondary dust lip which protects the other lip against dust and other fine contaminants. This type of radial oil seal is recommended for use in polluted environments. Radial Oil Seals are also known as Rotary Shaft Seals, consisting of a rubber sealing lip, metal case and a spiraled tensioning spring Their function is to keep oil and grease within the system dirt and dust out.

  • Size Range: 10 mm to 250 mm
  • Temperature: -40 °C to 200 °C
  • Pressure (max): 0,05 MPa
  • Speed (max) 15 m/s

Material Information for the product(s) on this page

N7M
Colour
black
Basic Material
NBR/metal
Commercial Description
A 70 durometer NBR bonded to a steel case. Comes with a steel spring. The properties of the nitrile rubber depend mainly on the ACN content which ranges between 18 % and 50 %.  In general it has good mechanical properties with an operating temperaturs range of between -30 °C and +100 °C. NBR is mostly used with mineral based oils and greases and is a good choice for standard applications.

Basic Material
NBR/metal
Commercial Description
An 80 durometer NBR bonded to a steel case. Comes with a steel spring. The properties of the nitrile rubber depend mainly on the ACN content which ranges between 18 % and 50 %.  In general it has good mechanical properties with an operating temperature range of between -30 °C and +100 °C (for a short period of time up to +120 °C). NBR is mostly used with mineral based oils and greases and is a good choice for standard applications.
V8V
Colour
brown
Basic Material
FKM/metal
Commercial Description
An 80 durometer FKM with a standard steel case. Comes with a stainless steel spring. FKM is an elastomer material known especially for its non-flammability, low gas permeability and excellent resistance to ozone, weathering, and ageing.  The operating temperatures of the fluorocarbon rubber range between -20 °C and +200 °C.  FKM is also often used with mineral based oils and greases at high temperatures.
