Pendelkugellager: Ein Leitfaden zu Nachsetzzeichen und Bezeichnungsschema
Self-aligning ball bearings are a fascinating component in the world of rolling bearings. Their unique ability to compensate for angular misalignment makes them indispensable in applications where the shaft and housing are not optimally aligned or where the shaft can bend. In this blog post, we will decode the suffixes and designation scheme of self-aligning ball bearings to provide you with a deeper understanding of these specialized bearings.
What are Self-aligning ball bearings?
Self-aligning ball bearings are double-row rolling bearings that consist of an inner ring with two ball raceways and an outer ring whose raceway has the shape of a hollow sphere. This construction allows for angular movement, which can be used to compensate for misalignments, shaft deflections, or alignment errors.1.
TVH
"TVH" refers to a cage made of glass fiber reinforced polyamide, which is commonly used in spherical roller bearings. This type of cage offers good strength and is suitable for high speeds15.
EKTN9
"EKTN9" refers to a spherical roller bearing with a tapered bore and a cage made of glass fiber reinforced polyamide (Polyamide 66). The tapered bore allows for mounting on tapered shaft seats or with clamping sleeves, which enables easy and precise installation. The suffix "TN9" indicates the polyamide cage.121418.
TN9
"TN9" stands for a cage made of fiberglass-reinforced polyamide that is ball-guided. This cage is often the standard in many self-aligning ball bearings and provides a good balance between strength and flexibility at high speeds.15.
TV
"TV" also stands for a cage made of polyamide, similar to "TVH" and "TN9". This type of cage is used in self-aligning ball bearings to ensure high speed suitability and good strength.15.
TNG
The suffix "TNG" could not be found in the provided sources. It is possible that it is a specific or less common suffix that is not listed in the standard catalogs. These suffixes provide important information about the design and materials of the cages in spherical roller bearings, which are essential for the performance and application of the bearing.
Understanding the designation scheme
The designation scheme for self-aligning ball bearings is standardized and provides important information about the bearing. For example, the designation "2306 E-2RS1KTN9" stands for a self-aligning ball bearings with the following characteristics:
- 2306: The base number that indicates the series and size of the bearing.
- E: A variant that indicates a specific bearing construction.
- 2RS1: Seals on both sides of the bearing.
- K: A conical bore.
- TN9: A cage made of fiberglass-reinforced polyamide15.
Fazit
Self-aligning ball bearings are an essential component of many machines and systems. Understanding the suffixes and the designation scheme is crucial for selecting the right bearing for your application. Equipped with this knowledge, you can optimize the performance of your machines and maximize the lifespan of your bearings.
