Component Specifications

Definition
A precision-engineered rotating shaft and bearing system designed to support radial and axial loads while enabling smooth rotation of compaction drums in industrial machinery. This assembly provides structural integrity, precise alignment, and controlled motion transfer between the drum and drive mechanism.
Working Principle
The shaft transmits torque from the drive system to the compaction drum while bearings reduce friction through rolling elements (balls or rollers) between inner and outer races, allowing smooth rotation under heavy compressive loads.
Materials
Shaft: AISI 4140 alloy steel (hardened to 45-50 HRC); Bearings: Chrome steel (GCr15) with polyamide or brass cages; Seals: Nitrile rubber or fluorocarbon
Technical Parameters
  • Mounting Adapter sleeve or direct fit
  • Lubrication Grease (NLGI 2) or oil bath
  • Bearing Type Spherical roller bearing or tapered roller bearing
  • Speed Rating Up to 1500 rpm
  • Load Capacity Dynamic: 200-800 kN, Static: 300-1200 kN
  • Shaft Diameter 50-150 mm
  • Operating Temperature -20°C to +120°C
Standards
ISO 281, ISO 1132, DIN 5412, DIN 620

Frequently Asked Questions

What lubrication is recommended for compaction drum bearings?

Use high-temperature lithium-based grease (NLGI 2) with EP additives. For continuous operation, automatic lubrication systems are recommended to extend bearing life.

How often should mounting shaft alignment be checked?

Alignment should be verified during installation and after every 500 operating hours or following significant impact loads to prevent premature bearing failure.

Can these bearings handle both radial and axial loads?

Yes, spherical roller bearings are specifically designed to accommodate combined radial and axial loads, making them ideal for compaction applications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
