SKF Four Point Contact Ball Bearing 20 mm ID 52 mm OD 15 mm Race Width QJ 304 MA

SKF QJ 304 MA is a precision-engineered single-row four-point contact ball bearing featuring a 20 mm inside diameter, 52 mm outside diameter, and 15 mm race width. It is designed for applications requiring high rotational speeds and combined radial and axial load support. This bearing type is ideal for use in spindle assemblies, rotary tools, high-rpm testing rigs, balancing machines, precision index tables, and turntables.

The bearing utilizes steel balls as rolling elements and a machined brass cage to reduce internal friction, resulting in smooth and efficient rotation. Its 35° contact angle enables it to accommodate bidirectional axial loads, making it suitable for demanding operating conditions. The CN internal clearance allows a controlled axial play to enhance load distribution and operational reliability.

With a dynamic load rating of 32 kN and a static load rating of 21.6 kN, the QJ 304 MA supports both operational stresses and stationary loads effectively. It features an open-ended design for easy access and maintenance. The bearing requires a parallel bore for proper fitting and seating.

Originating from Germany, this SKF bearing adheres to stringent quality standards for high performance and longevity in industrial and mechanical applications. 24,000 rpm limiting speed for high-speed operation. 35° contact angle for improved axial load handling.

Machined brass cage for reduced friction and smooth running. Steel ball rolling elements for durability. CN internal clearance for controlled axial play under load. Dynamic load capacity of 32 kN for robust operation. Static load capacity of 21.6 kN for high stationary loads.
