Hardened steel sliding bearings can be produced acc. customer’s drawing with oil grooves, oil holes etc.

Carbon steel face-hardened till 1,5 mm depth to hardness min. 52 HRC with more ductile core.

High load capacity over 150 N/mm2, suitable for rotary and oscillating movement, long re-lubrication interval, excellent wear resistance under high load with lower speed, good resistance to shock loads, good characteristic by using in the presence of abrasive media or dirty environment.

The initial pre-lubrication at assembly required.
