EGB 4050 E40 B INA Plain Bush 40x44x50 mm

Overview

EGB 4050 E40 B INA is a cylindrical plain bush with dimensions of 40x44x50 mm, designed for maintenance-free plain bearing arrangements. It belongs to the INA metal-polymer plain bearing range and combines a metallic backing structure with an E40 sliding layer. The compact thin-walled design is suitable for applications where limited radial installation space and reliable sliding performance are required.

Industrial Applications

INA EGB 4050 E40 B can be used in production machinery, material handling equipment, articulated mechanisms, agricultural machinery, construction equipment and automation systems. This type of plain bush is particularly useful in bearing positions where access for regular lubrication is difficult or where a maintenance-free bearing solution is preferred.

Construction

The bush has a 40 mm inside diameter, 44 mm outside diameter and 50 mm length. Its thin-walled design enables compact plain bearing arrangements with limited radial space. The metallic backing provides mechanical support, while the composite sliding layer forms the functional contact surface between the bush and the mating shaft.

E40 Sliding Material

E40 identifies the INA sliding material used in this maintenance-free plain bearing design. The material system is engineered for low-friction sliding performance and wear resistance without routine relubrication. Correct selection requires consideration of surface pressure, sliding velocity, temperature, mating shaft properties and environmental conditions.
