Photo of crescent ring Drawing of Metric Crescent Rings

Radially fitted circlips for shafts with grooves. Crescent Rings provide a shallow but uniform shoulder on relatively small shaft diameters. Higher resistance to thrust loads than standard 'E' type circlips.

Neat appearance and suitable for applications where small clearance dimensions are important.
(Certain sizes are available in Stainless Steel)

Standard material: Carbon Spring Steel - Standard Finish: Phosphate and Oil.
