Frequently Asked Questions
What are sintered bronze bearings?
Sintered bronze bearings are porous metal plain bearings manufactured through a powder-metal process. They provide reliable sliding performance and are available in a range of metric and imperial sizes. Our Sintered Bronze/Iron bearings are manufactured to specified metric tolerances and conform to ISO 2795:1991.
How does oil impregnation work?
Oil impregnation fills the pores within the sintered bearing material with lubricant. During operation, the oil can provide lubrication at the bearing surface, helping reduce friction and wear. This makes an oil impregnated sleeve bushing suitable for applications where consistent lubrication is required.
What is the difference between sintered bronze and iron?
Sintered bronze and sintered iron offer different material characteristics and performance properties. The appropriate material depends on factors such as load, speed, operating environment, and application requirements. Our sintered bronze iron plain bearings provide options for different industrial applications.
What loads can these bearings handle?
The load capacity of Sintered Bronze/Iron bearings depends on the bearing dimensions, material, operating speed, lubrication, and application conditions. Our team can help determine the appropriate bearing specifications based on your required operating parameters.
