Rotary Shaft Seal 45x62x7 NBR AO/TC is a double lip radial shaft oil seal for rotating shafts. Its nominal dimensions are 45x62x7 mm, corresponding to a 45 mm shaft diameter, 62 mm outside diameter and 7 mm width. The seal is manufactured from NBR - Nitrile Butadiene Rubber. Its AO/TC configuration incorporates a spring-loaded primary sealing lip and an additional dust lip. Correct replacement selection should consider the dimensions, material and double lip construction rather than dimensions alone.
Product type: Radial shaft oil seal / rotary shaft seal
Dimensions: 45x62x7 mm
Shaft diameter d: 45 mm
Outside diameter D: 62 mm
Width B: 7 mm
Material: NBR - Nitrile Butadiene Rubber
Design: AO/TC
Lip configuration: Double lip
Primary sealing lip: Spring-loaded
Additional dust lip: Yes
The principal dimensions are:
Shaft diameter d: 45 mm
Outside diameter D: 62 mm
Width B: 7 mm
Complete dimensions: 45x62x7 mm
The 45 mm inside diameter corresponds to the nominal shaft diameter at the sealing position.
The 62 mm outside diameter corresponds to the nominal housing bore diameter.
The axial width of the seal is 7 mm.
All three dimensions should be verified when identifying a replacement rotary shaft seal.
Sealing material: NBR - Nitrile Butadiene Rubber
NBR, also known as nitrile rubber or Buna-N, is an established elastomer family widely used in radial shaft sealing technology.
NBR compounds are commonly used in sealing systems involving many compatible mineral oils and lubricating greases.
Exact compatibility depends on the specific NBR compound, operating medium, additives, temperature and actual service conditions.
An FKM/FPM, ACM, VMQ or other elastomer seal measuring 45x62x7 mm should not automatically be considered technically equivalent.
The sealing configuration is:
AO/TC - Double Lip
Primary sealing lip: Spring-loaded
Additional dust lip: Yes
The primary lip operates against the rotating shaft and performs the principal sealing function.
The additional lip provides a secondary barrier on the external side of the primary sealing area and helps restrict external contamination from reaching the main sealing interface.
The double lip configuration is therefore an important part of the technical identification of the seal.
The primary sealing lip operates directly against the rotating shaft surface.
A garter spring supports the primary lip and helps maintain radial contact between the sealing edge and the shaft.
During installation, the sealing edge should be protected against sharp edges, threads, keyways and other shaft features that could damage or fold the lip.
The orientation of the primary sealing lip relative to the retained medium should also be verified during assembly.
The AO/TC construction incorporates an additional dust lip.
This secondary lip forms an additional barrier between the external environment and the primary sealing interface.
The additional dust lip distinguishes the double lip AO/TC configuration from a basic single lip rotary shaft seal.
When selecting a replacement, the required lip configuration should therefore be checked in addition to the 45x62x7 mm dimensions.
The 45x62x7 mm oil seal is designed for radial sealing around a rotating shaft.
Nominal shaft diameter: 45 mm
Nominal housing diameter: 62 mm
Seal width: 7 mm
Material: NBR
Design: AO/TC - double lip
Before installation, the requirements of the specific machine should also be checked for sealing medium, elastomer compatibility and operating conditions.
NBR is widely used in rotary shaft seals operating with compatible mineral oils and lubricating greases.
This does not mean that every NBR compound is universally compatible with every oil, fuel or technical fluid.
Before installation, verify:
Operating medium: To be verified
Compatibility with NBR: To be verified
Operating temperature: Dependent on the specific NBR compound
Actual operating conditions: To be verified
Generic temperature, pressure or speed limits from another 45x62x7 NBR oil seal should not be transferred to this product without confirmation.
The AO/TC double lip configuration incorporates a spring-loaded primary sealing lip and an additional dust lip.
A basic single lip version does not incorporate the same additional dust lip configuration.
Consequently, two oil seals with identical 45x62x7 mm dimensions can have different sealing constructions.
If an application requires a double lip seal, matching dimensions alone are not sufficient when selecting an equivalent.
When comparing replacement seals, verify:
Shaft diameter d: 45 mm
Outside diameter D: 62 mm
Width B: 7 mm
Material: NBR
Design: AO/TC - double lip
Primary spring-loaded lip: Yes
Additional dust lip: Yes
Operating medium: To be verified
Actual service conditions: To be verified
Matching 45x62x7 mm dimensions alone does not establish complete technical interchangeability.
The material and sealing lip configuration should also correspond to the requirements of the application.

The dimensions are 45x62x7 mm: 45 mm shaft diameter, 62 mm outside diameter and 7 mm width.
The sealing material is NBR - Nitrile Butadiene Rubber.
Yes. The AO/TC version uses a double lip sealing configuration.
Yes. The primary sealing lip is supported by a garter spring.
Yes. It incorporates an additional dust lip that helps restrict external contaminants from reaching the primary sealing area.
Not necessarily. Matching the 45x62x7 mm dimensions alone does not confirm interchangeability. The replacement should also correspond to the required NBR material and double lip construction.
It specifies a 45 mm nominal shaft diameter, 62 mm outside diameter and 7 mm seal width.
For this product, AO/TC identifies a double lip radial shaft seal configuration with a spring-loaded primary sealing lip and an additional dust lip.
They are commonly used in different manufacturer and market nomenclature systems for comparable double lip shaft seal configurations. They should not, however, be assumed to be universally identical across every manufacturer's design system.
Interchangeability should not be assumed. The additional dust lip is part of the sealing configuration and may be required by the application.
NBR is commonly used with many compatible mineral oils and lubricating greases. Exact compatibility depends on the specific medium, additives, temperature and operating conditions.
No. The NBR material, AO/TC double lip construction, sealing medium and actual operating conditions should also be verified.
45x62x7 NBR AO/TC is a double lip rotary shaft oil seal with a 45 mm shaft diameter, 62 mm outside diameter and 7 mm width. The seal is manufactured from NBR and incorporates a spring-loaded primary sealing lip plus an additional dust lip. The AO/TC configuration distinguishes it from a basic single lip seal. Correct replacement selection should consider the 45x62x7 mm dimensions, NBR material and double lip construction.
