Deep Groove Ball Bearings SKF 6328 M/C3

The SKF 6328 M/C3 deep groove ball bearing, measuring 140 × 300 × 62 mm, offers a high level of operational reliability under thermal conditions thanks to its brass cage and C3 clearance.

This single-row deep-groove ball bearing 6328 M/C3 from SKF primarily accommodates radial loads as well as axial forces in both directions. The open design, without integrated sealing washers, allows for direct lubrication via the surrounding machinery. Manufactured from standard rolling-element bearing steel 100Cr6 with a cylindrical bore and an outer ring without a flange or groove, this large bearing complies with the standard tolerance P0/PN or ABEC 1.

What is the 6328 M/C3 deep groove ball bearing suitable for in industrial applications?

Design engineers and maintenance technicians typically use this size for bearing arrangements subject to high radial and axial loads, as well as demanding mechanical stresses. Thanks to its solid brass cage, the bearing guides the rolling elements accurately even in the presence of vibrations or rapid changes in rotational speed. As the component has an open design, it is primarily suitable for sealed housings with an existing oil or grease circulation system. The permissible temperature range is from –20 to +150 degrees Celsius.

What are the advantages of combining C3 radial clearance with a brass cage?

The design with a slightly increased radial clearance (C3) compensates for thermal expansion that may occur between the shaft and the housing during operation. When a tight fit is selected, this radial clearance helps to prevent the rolling elements from seizing up when the bearing heats up. The brass material also reduces friction at the guide edges and withstands vibration loads. During design, it is important to ensure that external housing seals protect the bearing from ingress of dirt.
