TSS tipo TRA e Stefa tipo CB
I paraolio radiali Tipo TRA sono delle tenute con diametro esterno completamente rivestito in gomma e un unico labbro di tenuta. Questo tipo non è idoneo per essere utilizzato in ambienti molto inquinati. I Paraolio radiali sono anche noti come Tenute albero rotatorio e sono costituiti da una labbro di tenuta in gomma, involucro metallico e molla a spirale. Hanno il compito di tenere l'olio e il grasso all'interno dell'impianto e, al contempo, di non far penetrare la polvere e lo sporco.
Capacità di tenuta
- Gamma: da 10 mm a 250 mm
- Temperatura: -40 °C a 200 °C
- Presión (máx): 0,05 MPa
- Velocità (max) 15 m/s

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.
N8M
Colour

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.
VCV
Colour
brown
Basic Material
FKM/metal
Commercial Description
A 75 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.
