Angular Contact Ball B. SKF 3204 A-2RS1TN9/MT33
The SKF 3204 A-2RS1TN9/MT33 double-row angular contact ball bearing, with a 20 mm bore, accommodates combined radial and axial loads in both directions.
The SKF 3204 A-2RS1TN9/MT33 double-row angular contact ball bearing is designed for demanding bearing applications. Thanks to its 30-degree contact angle, this unit accommodates both radial and axial loads in both directions. The unit has the following key dimensions: 20 mm bore, 47 mm outside diameter and 20.6 mm width. Manufactured from standard roller bearing steel 100Cr6, the unit offers high dimensional stability. You receive a roller bearing that is ready for use and pre-filled with special grease.
What is the 3204 A-2RS1TN9/MT33 angular contact ball bearing suitable for?
This double-row roller bearing is particularly suitable for compact designs subject to tilting moments and alternating axial forces. In mechanical engineering, the O-arrangement of the raceways ensures a rigid bearing arrangement in confined spaces. The bearing is primarily used on rotating shafts that carry combined loads and offer limited axial installation space. Thanks to its sealed design, the lubricant remains inside whilst contaminants are kept away from the raceways.
What properties do the polyamide cage and special MT33 grease offer?
The integrated polyamide cage ensures low-noise guidance of the rolling elements and reduces friction during operation. In combination with MT33 grease, the assembly is designed for a temperature range of –30 °C to +110 °C. The double-sided lip seals made from 2RS1 material protect the system from dust and moisture. Manufactured to tolerance class P6, this bearing also meets increased requirements for concentricity and dimensional accuracy.
What are the dimensions of the 3204 A-2RS1TN9/MT33 angular contact ball bearing?
The bearing has an inside diameter of 20 mm, an outside diameter of 47 mm and a total width of 20.6 mm. It has a cylindrical outer ring without a flange or circumferential groove and fits into standardised housing bores.
What does the suffix MT33 mean at SKF?
The designation MT33 indicates that the unit has been factory-filled with a special grease designed for medium operating temperatures. The grease is suitable for a temperature range of -30 °C to +110 °C and is suitable for typical industrial applications without the need for relubrication.
What is the function of the 2RS1 seal in this angular contact ball bearing?
The double-sided lip seals seal the raceways against the ingress of dirt, dust and moisture. At the same time, they retain the factory-applied grease inside the bearing unit, meaning that the bearing is designed for sealed operation.
What makes the TN9 polyamide cage stand out?
The polyamide cage guides the balls with low internal friction and is characterised by its elastic material properties. Compared with metal cages, this material enables quiet operation and helps to reduce the unit’s weight.
What is the bearing clearance and tolerance class of this component?
The bearing is manufactured with standard radial clearance and complies with tolerance class P6 or ABEC 3. This classification implies tighter dimensional and running tolerances than those of standard bearings, which facilitates more precise guidance of rotating shafts.
Why is a double-row angular contact ball bearing with a 30-degree contact angle chosen?
Two rows of balls, with a contact angle of 30 degrees, absorb axial forces in both directions as well as tilting moments. This design combines the function of two single-row bearings in a compact, ready-to-install component.
