6304 PPL Deep Groove Ball Bearing 20x52x15

Open Bearing Designed for Oil-Lubricated Industrial Drive Systems

The 6304 PPL Deep Groove Ball Bearing 20x52x15 is an open single row bearing developed for industrial applications where continuous lubrication is supplied by oil circulation, oil bath or centralized lubrication systems. Unlike sealed bearing versions, the open design allows unrestricted lubricant flow through the raceways, improving heat dissipation and ensuring dependable performance during continuous operation. It is an excellent solution for industrial gearboxes, electric motors, pumps and production machinery operating in clean, lubricated environments.

Natural entity coverage includes deep groove ball bearing, open ball bearing, radial ball bearing, rolling bearing, electric motor bearing, gearbox bearing, transmission bearing, pump bearing, industrial bearing and OEM replacement bearing.

Application in Industrial Systems

The 6304 PPL bearing is widely installed in machinery equipped with continuous lubrication systems.

Typical applications include:

• Industrial gearboxes
• Speed reducers
• Electric motors
• Oil pumps
• Machine tools
• Production machinery
• Power transmission systems
• Hydraulic equipment

FAQ

What is the difference between an open bearing and a 2RS bearing?

An open bearing has no seals, allowing lubricant supplied by the machine to circulate freely. A 2RS bearing uses rubber seals to retain factory grease and protect against contamination.

Does the 6304 PPL require external lubrication?

Yes. Open bearings are intended to operate with oil or grease supplied by the machine's lubrication system.

Where is the 6304 open bearing commonly used?

It is commonly installed in industrial gearboxes, electric motors, machine tools, hydraulic systems, pumps and other equipment operating with continuous lubrication.

Can this bearing replace other open 6304 bearings?

Yes. The standardized dimensions of 20x52x15 mm allow it to replace compatible open 6304 bearings when the original technical specifications are identical.
