Product Overview

This tin bronze bushing features internal spiral oil grooves machined into the bore surface, designed for applications requiring external oil lubrication. The spiral groove pattern ensures uniform oil distribution across the entire sliding surface, reducing friction and preventing metal-to-metal contact. The tin bronze substrate offers excellent corrosion resistance and high load capacity up to 200 N/mm². The oil groove design allows for effective lubricant retention and distribution, making it suitable for applications with continuous or intermittent oil supply. Custom groove patterns, dimensions, and lubrication configurations available for specific application requirements.

Frequently Asked Questions

Spiral oil grooves provide more uniform lubricant distribution across the entire bearing surface. The spiral pattern ensures that oil is carried to all areas of the bore, reducing localized friction and wear.

Standard industrial gear oils or hydraulic oils with viscosity ISO VG 32-68 are typically recommended. Consult specific application requirements for appropriate lubricant selection.

Yes. Radial oil holes can be added to allow external oil supply directly into the groove pattern. Hole locations and sizes can be customized based on application requirements.

Press fit using a tool that contacts the bushing end uniformly. Ensure the oil grooves are not damaged during installation. Housing bore should be within ISO H7 tolerance.

Replace when bore diameter wear exceeds 0.08mm, when the oil groove depth has reduced by more than 50%, or when the bushing shows signs of scoring or galling.
