SKF FRB 4/120 Locating Ring -, 55 mm ID

This locating ring is a cast iron component designed to position and support rotating or fixed assemblies within industrial equipment. It is used in contexts where accurate axial location is required to maintain alignment and assembly stability, particularly in automation and mechanical systems.

• 80mm centre height improves alignment consistency during installation
• 110mm depth supports robust axial seating for mounted components
• 110mm inside diameter accommodates common shaft or bore interfaces
• 275mm overall length enables integration into extended flanged assemblies
• 16mm mount holes allow secure bolting to mating structures
• 230mm mount hole pitch ensures repeatable positioning between fixings

• Suitable for locating flanged housings in automated machinery
• Ideal for aligning motor-to-gearbox interfaces in electrical drives
• Used with control cabinets requiring precise fixture points
• Can be used for jigs and fixtures in electronics assembly lines
• Used for component retention in mechanical manufacturing cells

The part is MADE from cast iron which provides inherent mass and damping characteristics that reduce transmission of high-frequency vibration in mounted assemblies.

The 230mm centre-to-centre spacing combined with 16mm holes spreads clamping forces across the flange, reducing local stress and improving load sharing among fastenings.

The internal aperture is 110mm so larger shaft interfaces would require an adaptor or machining to increase the bore size to fit alternate diameters.

Account for the 275mm length and 110mm height when planning clearances and ensure the 80mm centre height aligns with neighbouring axial datum references.
