Structure and Working Principle
The F 224671 BBU uses a closed bearing cup with 21 hardened steel needle rollers arranged around the cross-shaft journal. The large number of long, small-diameter rollers distributes radial loads over a broad contact area while maintaining compact dimensions. A PA66-GF thrust washer, NBR sealing ring and grease charge support reliable lubrication and help prevent contamination during automotive driveline operation.
Automotive Application and Quality Validation
This bearing cup is engineered for the trunnion cap position of an automotive universal joint. It supports radial loads and oscillating motion transmitted through the cross shaft in propeller-shaft and driveline assemblies. Production samples have been accepted by an automotive component manufacturer and meet the quality requirements applicable to automotive production use.
Common Applications
- Automotive universal joint cross-shaft assemblies
- Propeller shaft and driveshaft joints
- Commercial vehicle driveline components
- Industrial cardan shaft assemblies
Selection Notes
Confirm the exact model, 20 mm journal interface, 30 mm housing bore, 21.5 mm overall width, load ratings, grease specification, seal arrangement and installation fit before ordering. Final suitability should be verified against the mating cross shaft, operating angle, speed, temperature, lubrication interval and vehicle duty cycle.
