30309 MGK Tapered Roller Bearing 45x100x27.25

30309 MGK Tapered Roller Bearing 45x100x27.25

30309 MGK is a durable single row tapered roller bearing designed for operation under heavy radial and axial loads in demanding industrial, automotive and machinery applications. The 45x100x27.25 mm construction provides high rigidity, stable operation and excellent durability even under dynamic loading conditions.

Tapered roller bearings of the 30309 series use tapered raceways and tapered rollers allowing simultaneous support of:

• heavy radial loads
• axial loads in one direction
• combined loads
• dynamic loads in heavy duty drive systems

The separable construction allows independent mounting of the inner and outer ring assemblies, significantly simplifying installation, preload adjustment and maintenance procedures. Tapered roller bearings are commonly mounted in pairs in O or X arrangements to achieve increased axial rigidity and precise shaft guidance.

The 30309 MGK bearing is widely used in:

• industrial gearboxes
• wheel hubs
• drive systems
• agricultural machinery
• reducers
• conveyor equipment
• construction machinery
• applications requiring high axial load capacity

The tapered raceway geometry improves load distribution and reduces operational stress, resulting in extended service life of the bearing assembly.

The phrase 30309 MGK 45x100x27.25 tapered roller bearing is frequently searched in gearbox maintenance applications and heavy duty industrial drive system servicing.
