Igus 2 Hole, EFOM-20 20 mm ID

Igus igubal Series Bearing Unit, 20mm Inside Diameter, 5500N Static Load Rating - EFOM-20

This bearing unit is a self-aligning support designed for rotating shafts in automation and mechanical assemblies. It provides a housed bearing solution that simplifies installation and compensates for minor misalignment, making it suitable for continuous operation in industrial equipment where straightforward mounting and dependable shaft support are required.

Features and Benefits:

• Inside bore 20mm delivers direct integration with standard shaft sizes
  Static load capacity 5500N supports substantial stationary forces
  Two mounting holes permit secure attachment and stable operation
  Mount hole spacing 69.1mm aligns with common fixture patterns
  Mount holes sized 8.4mm accept standard metric fasteners
  Manufactured from Igumid G material for wear-resistant contact surfaces

Applications

• Suitable for conveyor shaft support in manufacturing lines
  Ideal for actuator and drive assemblies in automation systems
  Used with rotary stages in electronic assembly equipment
  Can be used for motor shaft bearing support in electrical enclosures

What mounting footprint is required for fitting?

The unit requires a centre-to-centre hole spacing of 69.1mm with two holes sized for 8.4mm fasteners to secure it to a mounting surface.

Which shaft diameter will fit without additional adapting?

A 20mm shaft can be installed directly into the internal bore without the need for inserts or adaptors.

How does the material choice affect contact performance?

The Igumid G construction offers a polymer contact surface that reduces friction and withstands sliding wear in bearing interfaces.

How compact is the unit for space-constrained assemblies?

The housing measures 89mm in width and 46.5mm in length with a depth of 20 mm, allowing installation where lateral space is limited.

What static loads can the support resist when stationary?

It is rated to carry a static load of 5500 N, suitable for applications with significant non-rotational forces.

Notes

IGUBAL® bearings are designed to run with a clearance between the shaft and the inside diameter of the ball, to prevent the ball turning in the housing.
