AC4631 Heavy Duty Excavator Planetary Gearbox Bearing 230x310x38mm Chrome Steel Construction

The AC4631 heavy duty excavator planetary gearbox bearing is engineered for demanding construction equipment applications, featuring dimensions of 230×310×38mm and robust construction for extended service life.

• Stable performance with low operating noise
• Designed to handle both thrust and radial loads
• Tapered roller bearing design for excavator applications
• Multiple precision grades available for various requirements

Tapered roller bearings consist of four interdependent components: the cone (inner ring), the cup (outer ring), the tapered rollers (rolling elements), and the cage (roller retainer). These bearings are uniquely designed to manage both thrust and radial loads between rotating and non-rotating members. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads.

Proper installation and removal methods should be based on bearing structure, size, and component compatibility. During installation, pressure should be applied directly to the bearing ring tight end surface, not through the bearing rolling elements, to prevent surface indentation that could affect performance and cause damage. Avoid applying pressure to bearing cages, seals, dust covers, and other easily deformed components.
