Planet Cage Roller
Manufactured to OEM specifications, this roller element is engineered for high compressive strength, wear resistance, and precise dimensional control.
Planet Cage Roller Newage 85M Gearbox - OEM Number: T50612
Part No.
HMP4267
The Newage 85M Gearbox Planet Cage Roller (OEM T50612) is a direct replacement internal transmission bearing component used within the planetary carrier assembly of Newage 85M gearboxes fitted to Thwaites, Terex, Benford, and Mecalac site dumpers. It is designed to support and guide rotating planetary gears within the cage assembly, ensuring smooth rotation and correct load distribution under high torque conditions.
Manufactured to OEM specifications, this roller element is engineered for high compressive strength, wear resistance, and precise dimensional control. It operates within the confined planetary gear set where it is exposed to continuous rotation, shock loading, and heavy radial forces typical of off-highway dumper applications.
FUNCTION AND OPERATION
- Supports planetary gear rotation within the cage assembly
- Reduces friction between moving gear elements
- Maintains correct gear alignment and spacing
- Distributes radial loads within the planetary carrier system
- Ensures smooth and efficient gearbox operation under torque

- Design: Precision-ground OEM-spec component for exact fit within planetary cage system
The Newage 85M gearbox is a heavy-duty 3-speed forward / 1 reverse transmission widely used in site dumpers, with a rugged constant-mesh design built for sustained torque loads in low gears. Internal planetary components such as cage rollers are critical to maintaining gear integrity under harsh operating conditions.
TYPICAL APPLICATIONS
Suitable for a range of machinery fitted with Newage 85M gearboxes, including:
- Thwaites site dumpers (various tonnage classes)
- Terex / Benford / Mecalac dumpers
- Construction and earthmoving machinery
- Off-highway transmission systems using 85M gearbox variants
- Planetary carrier assemblies within 40M/85M drivetrain platforms
IMPORTANT INFORMATION
Always confirm the correct OEM part number and gearbox variant before ordering, as planetary cage components can vary between 40M and 85M versions and across different carrier revisions. Incorrect roller selection can result in uneven gear loading, increased gearbox noise, accelerated wear, or failure of the planetary assembly under load.
