XB05855
Retaining Ring, 1-1/8 in
SAF-Holland

A precision element designed to sit in a groove on a shaft or bore, this component provides axial retention for a companion part in heavy-duty assemblies. With an inner diameter of 1.12 inches, it aligns with standard groove profiles used in drivetrains, gear trains and hydraulic housings, enabling straightforward installation and repeatable service. In operation, the seating geometry resists axial movement under end thrust, torque spikes and vibration, helping to preserve accurate alignment and prevent components from migrating along the shaft. The compact geometry supports reliable retention without adding significant axial length, which is critical in tight-pack drivetrains and wheel-end assemblies where space is at a premium. Proper groove width and seating depth are essential for a secure fit; when installed in compatible grooves, the ring provides consistent axial containment across cycles and shock loads typical of commercial vehicle operation. VMRS code 059-001-123 identifies this as a retention element used to control axial displacement in rotating assemblies. Within category 42798, it sits among similar circlip and retaining-ring variants designed for fast field servicing in transmissions, hubs and hydraulic blocks. For best results, confirm groove tolerances and install with the appropriate tooling; note that cross-references are not provided for this SKU.
