» DTX BEARING RANGE

DTX – DUROTEX bearings and washers are suitable for rotating and oscillating movement, less maintenance requirements due to lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviors & above all good resistance to impact loads. It has longer service life under low speed and high load.

This new material uses the PTFE fiber fabric overlay on steel backing, the fabric is with high load capacity and much longer operating life comparing with conventional 3-layer bushes.This material is used in the equipments like suspension and auxiliary of agriculture, construction machines, cranes, hydraulic and mechanical jibs, ball butterfly and sluice valves, water pumps and chemical industries etc.
