SNR ES212 G2 Insert Ball Bearing 60x110 mm

What is the SNR ES212 G2 Bearing?

The SNR ES212 G2 is a radial insert ball bearing designed for mounted bearing units. It features a spherical outer ring, an extended inner ring and an eccentric locking collar for secure shaft mounting. The bearing belongs to the NTN-SNR ES200 series and is intended for applications where easy installation, simple maintenance and reliable shaft positioning are required. Its design allows slight misalignment between the shaft and housing while maintaining smooth bearing operation.

Construction and Operating Principle

The ES212 G2 is based on a deep groove insert ball bearing with a spherical outside diameter for installation in compatible bearing housings.

Main design features include:

• Spherical outer ring
• Extended inner ring
• Eccentric locking collar
• Single-lip seal
• Steel cage
• Relubrication capability
• C3 internal radial clearance

The eccentric locking collar provides secure shaft fixation and is particularly suitable for applications with predominantly unidirectional shaft rotation. The spherical outside diameter enables self-alignment within the bearing housing.
