FAQS on bearing 30x72x19

Q: What are the key specifications of a 30x72x19 bearing?

A: The 30x72x19 bearing has an inner diameter of 30 mm, an outer diameter of 72 mm, and a width of 19 mm. It is commonly used in industrial machinery requiring compact radial load support. Always verify load ratings and tolerances for your specific application.

Q: What is the difference between a ball bearing and a roller bearing in 30x72x19 sizes?

A: A 30x72x19 ball bearing uses spherical rolling elements for lower friction and higher speed, while a roller bearing employs cylindrical rollers for heavier radial loads. The choice depends on load type, speed, and space constraints. Both types are available in 30x72x19 dimensions.

Q: Can a 30x72x19 roller bearing replace a ball bearing of the same size?

A: While dimensions match, substitution depends on application requirements. Roller bearings handle higher radial loads but lower speeds than ball bearings. Consult technical specifications for load capacity and RPM limits before switching.

Q: What industries typically use 30x72x19 bearings?

A: These bearings are found in automotive transmissions, electric motors, and conveyor systems. Their mid-size range balances load capacity and space efficiency. Specific applications include gearboxes and pump assemblies.

Q: How do I identify if my 30x72x19 bearing is ball or roller type?

A: Inspect the rolling elements: balls are spherical, rollers are cylindrical. Check manufacturer markings like "RSR" (deep groove ball bearing) or "NJ" (cylindrical roller bearing). Cross-reference part numbers with supplier catalogs for confirmation.
