Application of Gen 1 (Press-In Bearings)

Gen 1 hub bearings, also known as press-in bearings, are the earliest and most traditional type of wheel bearing design. Unlike modern integrated hub assemblies (Gen 2/Gen 3), Gen 1 bearings consist of separate components that must be pressed into the wheel hub and steering knuckle.

1. Common Applications of Gen 1 Bearings

A. Older Passenger Vehicles (Pre-1990s to Early 2000s)

• Found in rear-wheel-drive (RWD) cars and some front-wheel-drive (FWD) models.

• Examples:

• Classic American cars (e.g., Ford Crown Victoria, Chevrolet Caprice).

• Older Japanese models (e.g., Toyota Hilux, Nissan Hardbody).

• European sedans (e.g., BMW E30, Mercedes W124).

B. Light Trucks & SUVs

• Used in solid rear axles of trucks and older SUVs.

• Examples:

• Ford F-150 (older models).

• Chevrolet Silverado (pre-2000s).

C. Heavy-Duty & Commercial Vehicles

• Some heavy trucks, trailers, and agricultural equipment still use press-in bearings due to their serviceability.

D. Motorcycles & ATVs

• Smaller press-in bearings are used in motorcycle wheel hubs and ATV axles.

2. Key Features of Gen 1 Bearings

✔ Separate Components – Bearings, hub, and seals are installed individually.
✔ Serviceable Design – Can be repacked with grease (unlike sealed Gen 2/Gen 3 units).
✔ Cost-Effective – Cheaper to replace individual bearings rather than the entire hub.
✔ Common in RWD & Heavy-Duty Axles – Often used in non-driven wheels (e.g., solid rear axles).
