45x65x12 NBR TC GRN is a double-lip radial shaft oil seal designed for a 45 mm shaft and 65 mm housing bore. The seal has a width of 12 mm and is manufactured from NBR - Nitrile Butadiene Rubber. Its TC design combines a spring-loaded primary sealing lip with an additional dust lip.
Complete technical identification:
GRN -> 45x65x12 mm -> NBR -> TC -> Double Lip
The key construction feature is the TC double-lip design.
The primary sealing lip provides the main sealing function on the rotating shaft, while the additional dust lip helps protect the primary sealing area against external contamination.
d - Shaft diameter: 45 mm
D - Housing bore diameter: 65 mm
B - Width: 12 mm
Dimensions: 45x65x12 mm
Material: NBR - Nitrile Butadiene Rubber
Design: TC
Configuration: Double lip
Brand: GRN
The seal is intended for a nominal:
45 mm shaft
and:
65 mm housing bore
All three dimensions should be verified before installation.
The TC design is a double-lip radial shaft oil seal configuration.
It consists of:
Primary sealing lip - provides the main dynamic sealing function against the rotating shaft.
Additional dust lip - provides an additional barrier against dust and external contamination reaching the primary sealing area.
The primary sealing lip is supported by a garter spring, which helps maintain radial contact between the sealing lip and the shaft.
The complete construction is therefore identified as:
TC -> spring-loaded primary lip + additional dust lip
This GRN seal may also be identified by the designation:
AO
For English-language technical content, TC is the more internationally recognizable designation for this double-lip radial shaft oil seal configuration.
The product can therefore be identified as:
45x65x12 NBR TC
or:
45x65x12 NBR AO
For this product, both designations refer to the required double-lip configuration with an additional dust lip.
The seal is manufactured from:
NBR - Nitrile Butadiene Rubber
NBR is widely used in radial shaft oil seals and is suitable for contact with many common mineral oils and lubricating greases.
Actual compatibility depends on the operating medium and working conditions.
For this specific GRN seal, the confirmed material is:
NBR
No product-specific temperature range, pressure limit or maximum shaft speed is assigned here without verified data for this exact product.
The two lips perform different functions.
The spring-loaded primary sealing lip operates dynamically against the rotating shaft and provides the main sealing function.
The additional dust lip is positioned toward the external environment and helps reduce the ingress of contaminants into the primary sealing area.
This distinction is important when comparing TC with a single-lip seal of the same dimensions.
Matching dimensions do not mean identical construction.
A single-lip:
45x65x12 mm oil seal
does not have the same sealing configuration as:
45x65x12 NBR TC
The TC version incorporates an additional dust lip.
When replacing this product, verify:
45 mm shaft diameter
65 mm housing bore diameter
12 mm width
NBR material
TC double-lip design
A 45x65x12 TC oil seal and a 45x65x12 COMBI seal can share the same nominal dimensions but are different sealing constructions.
This product is:
GRN 45x65x12 NBR TC - Double Lip Radial Shaft Oil Seal
It is not a:
45x65x12 COMBI seal
Dimensions alone should therefore never be used to establish interchangeability between TC and COMBI designs.
For replacement selection, verify the complete specification:
d: 45 mm
D: 65 mm
B: 12 mm
Material: NBR
Design: TC
Configuration: Double lip
Primary lip: Spring-loaded
Additional lip: Dust lip
The strongest technical identification is:
45x65x12 mm + NBR + TC + Double Lip
A dimensionally identical seal with another design should not automatically be considered interchangeable.
Brand: GRN
Product type: Radial shaft oil seal
Design: TC / AO
Configuration: Double lip
Dimensions: 45x65x12 mm
d - Shaft diameter: 45 mm
D - Housing bore diameter: 65 mm
B - Width: 12 mm
Material: NBR - Nitrile Butadiene Rubber
Primary sealing lip: Spring-loaded
Additional lip: Dust lip
The seal measures 45x65x12 mm: 45 mm shaft diameter, 65 mm housing bore diameter and 12 mm width.
TC identifies a double-lip radial shaft oil seal design with a spring-loaded primary sealing lip and an additional dust lip.
Yes. It is a double-lip radial shaft oil seal.
The material is NBR - Nitrile Butadiene Rubber.
The additional lip acts as a dust lip, helping reduce the ingress of external contamination toward the primary sealing area.
For this product, AO is the corresponding GRN designation for the TC double-lip configuration. In English technical content, TC is the preferred designation.
Not automatically. The TC version includes an additional dust lip, so construction as well as dimensions and material should be checked.
Not based on dimensions alone. TC and COMBI are different sealing constructions and should be selected according to the requirements of the installation.
