GRN® 105x130x12 TC NBR is a double-lip rotary shaft oil seal manufactured from nitrile rubber (NBR). The seal has dimensions of 105x130x12 mm: 105 mm shaft diameter, 130 mm outside diameter and 12 mm width. The TC design incorporates a primary sealing lip and an additional dust lip for additional protection of the sealing area against external contamination.

The designation 105x130x12 mm defines the three principal dimensions of the oil seal:
105 mm - shaft diameter
130 mm - outside diameter
12 mm - seal width
Complete product identification:
GRN® 105x130x12 TC NBR
When selecting a replacement, all three dimensions as well as the elastomer material and seal design should be verified.
GRN 105x130x12 TC is manufactured from NBR - nitrile butadiene rubber.
NBR is one of the most commonly used elastomers in rotary shaft seals. It provides good resistance to many mineral oils, lubricating greases and mineral-oil-based fluids.
For this reason, NBR oil seals are widely used in:
industrial machinery
gearboxes
drive systems
gear reducers
rotating mechanisms
technical equipment
agricultural machinery
construction machinery
Material compatibility should always be checked against the specific operating medium, temperature and actual working conditions.
GRN 105x130x12 uses a double-lip TC design.
The construction incorporates:
a primary sealing lip
an additional dust lip
The primary lip operates against the rotating shaft and provides the main sealing function.
The additional lip helps limit the ingress of dust, dirt and other external contaminants into the primary sealing area.
Different designation systems can be encountered for rotary shaft seal profiles.
For this product, the design may be identified as:
AO / TC
In international markets, TC is a widely recognized designation for a double-lip rotary shaft oil seal with a rubber-covered outside diameter, primary sealing lip and additional dust lip.
Profile codes are not completely standardized between all manufacturers. Therefore, when selecting an equivalent seal, the actual construction should be compared rather than relying solely on the AO or TC designation.

GRN 105x130x12 TC NBR Oil Seal
GRN® technical seals have been included in the TG Ersatzteile Polska product range since 2007.
The:
105x130x12 TC NBR
version is designed for radial sealing of a nominal 105 mm shaft in a 130 mm housing bore.
The seal width is 12 mm.
Its combination of NBR material and double-lip construction makes it suitable for appropriately designed industrial sealing arrangements where the operating conditions are compatible with nitrile rubber.
The seal is designed for radial sealing of rotating shafts in appropriately designed mechanical assemblies.
Typical application areas for this type of rotary shaft seal may include:
industrial machinery
gearboxes
transmissions
drive systems
gear reducers
agricultural machinery
construction equipment
mechanical assemblies with rotating shafts
Suitability for a particular machine must be determined from the technical requirements of the sealing arrangement.
Important selection factors include:
shaft diameter
housing bore diameter
seal width
operating medium
operating temperature
shaft speed
lubrication conditions
pressure
shaft surface condition
external contamination
Before ordering, verify:
Shaft diameter 105 mm.
Housing bore diameter 130 mm.
Seal width 12 mm.
NBR material.
TC double-lip design.
Requirement for an additional dust lip.
Operating medium.
Operating temperature.
Shaft speed.
Actual operating conditions.
Matching the 105x130x12 mm dimensions alone is not sufficient to confirm full interchangeability between two rotary shaft seals.
An NBR oil seal should not automatically be replaced with an FKM/FPM version simply because both seals have dimensions of 105x130x12 mm.
NBR and FKM/FPM are different elastomers with different chemical and thermal properties.
Before changing the seal material, verify:
operating medium
temperature
shaft speed
operating conditions
machine manufacturer's requirements
Identical dimensions do not mean identical operating characteristics.

Before installation:
thoroughly clean the shaft and housing bore
remove dirt and residues from the previous seal
inspect the shaft sealing surface
remove burrs that could damage the sealing lip
protect the sealing lip when passing over threads, grooves or sharp edges
use an appropriate installation tool
press the seal evenly into the housing
avoid deformation of the seal body
verify the correct installation orientation
Damage to the sealing edge during installation can cause leakage even when the correct seal has been selected.
The seal is designed for a 105 mm shaft and 130 mm housing bore and has a width of 12 mm.
It is manufactured from NBR - nitrile rubber.
Yes. The TC design incorporates a primary sealing lip and an additional dust lip.
TC is a widely used international designation for a double-lip rotary shaft oil seal with a primary sealing lip and an additional dust lip.
AO is a profile designation encountered in rotary shaft seal nomenclature for a construction with an additional dust lip. Profile terminology can vary between manufacturers.
AO and TC are used in different seal nomenclature systems for similar double-lip constructions. Because profile codes are not fully standardized between manufacturers, the actual seal construction should always be verified when selecting an equivalent.
NBR provides good resistance to many mineral oils and lubricating greases. Compatibility should nevertheless be verified for the specific fluid and operating conditions.
Not automatically. NBR and FKM/FPM have different material properties. Operating medium, temperature, shaft speed and other application requirements should be checked before changing the elastomer.
No. Oil seals with identical dimensions may differ in material, lip design, outside diameter construction and operating characteristics.
