Hub Assembly, Short Stud, Gen I C88
SAF-Holland

In heavy-duty trailer wheel-end assemblies, the hub body and bearing interface are engineered for Gen I C88 spindles to provide reliable rotation, consistent preload, and long service life under harsh road conditions. This short-stud configuration is optimized for compact mounting envelopes, reducing protrusion without compromising clamping load or wheel alignment. The design integrates precision seals and a robust seal-retention system to guard lubricants against contamination, while maintaining predictable friction characteristics across varying temperatures and speeds. For trailers operating in demanding environments, stable bearing preload minimizes runout, vibration, and heat buildup, contributing to quieter operation and extended bearing life between service intervals. The part’s VMRS classification highlights its role within the hub assembly family, reinforcing compatibility with SAF-HOLLAND Gen I C88 hubs and standard wheel-end patterns. Its inclusion in the Trailer Axle and Suspension category underscores its importance to axle alignment, wheel retention, and overall hub longevity. When selecting replacements or upgrades, confirm spindle compatibility and wheel pattern, and ensure proper torque application to preserve seal integrity and preload consistency. Protective labeling and documentation are standard, reflecting safety and handling guidelines typical for trailer wheel-end components.
