SKF Series QJ Ball Bearing, 20mm Inside Diameter, 52mm Outside Diameter - QJ 304 MA
This ball bearing is a single-row four-point contact component designed for applications requiring angular contact capacity and high rotational speed. It accommodates combined radial and axial loads within Compact assemblies and is supplied with an open-end configuration for straightforward integration into rotating machinery.
Features and Benefits:
• 24,000 r/min limiting speed supports high-speed operation
• 35° contact angle provides enhanced axial load handling
• Machined brass cage reduces internal friction for smoother running
• CN internal clearance allows controlled axial play under load
• Dynamic load capacity 32 kN increases operational load endurance
• Static load capacity 21.6 kN sustains high stationary loads
• 35° contact angle provides enhanced axial load handling
• Machined brass cage reduces internal friction for smoother running
• CN internal clearance allows controlled axial play under load
• Dynamic load capacity 32 kN increases operational load endurance
• Static load capacity 21.6 kN sustains high stationary loads
Applications
• Suitable for spindle and rotary tool assemblies
• Ideal for high-rpm testing rigs and balancing machines
• Used with drives requiring combined axial and radial support
• Can be used for precision index tables and turntables
• Used for machinery where open-ended access is required

What bore preparation is required for mounting?
The bore is parallel so a straight cylindrical housing bore is required for correct seating.
How does the bearing handle axial reversals in service?
The four-point contact geometry shares axial loads in both directions, enabling bidirectional axial load accommodation.
What materials are engaged in the rolling elements and cage?
The rolling elements are steel balls and the cage is MADE from machined brass.
What external dimensions must the housing accept?
The unit requires accommodation for a 20 mm inside diameter and a 52 mm outside diameter.
How thick is the section that contacts the races?
The race assembly presents a 15 mm overall width across the rolling elements.
