Challenge 08 Skk Gearbox Bearing

Challenge 08 Skk Gearbox Bearing

This is a replacement tapered roller bearing cone designed specifically for the planetary cage assembly in Challenge Model 08 and SKK mixer drum drive gearboxes. It supports the heavy radial and axial loads generated during the concrete mixing and discharging process. This bearing cone is an essential component when rebuilding or maintaining older Challenge Cook Bros, TL Smith, and Advance Mixer gearboxes to ensure smooth drum rotation and prevent catastrophic gear failure.

Key Features

• Tapered roller bearing cone design accommodates high radial and axial loads
• Direct fit for Challenge 08 and SKK 12-bolt and 24-bolt mixer gearboxes
• Mounts directly to the planetary cage assembly within the gearbox
