Thwaites Needle Bearing Newage 85M - OEM Number: T3412

The Thwaites Needle Bearing (Newage 85M) (OEM T3412) is a direct replacement transmission bearing designed for use within Newage 40M and 85M gearbox assemblies fitted to Thwaites site dumpers and related machinery. It is a precision-engineered needle roller bearing used to support rotating gearbox shafts while reducing friction and maintaining correct alignment under load.

Manufactured to OEM specifications, this bearing is designed for high radial load capacity, durability, and reliable performance in harsh operating environments. It operates within the gearbox where it is subjected to continuous rotation, vibration, and shock loading typical of heavy-duty site dumper use.

FUNCTION AND OPERATION

• Supports rotating shafts inside the gearbox assembly
• Reduces friction between moving transmission components
• Maintains accurate shaft alignment under load
• Improves gearbox efficiency and smooth gear engagement
• Withstands high vibration and shock loads in site conditions

TECHNICAL DETAILS

• OEM Part Number: T3412
• Type: Needle roller bearing
• OD: 37 mm
• Width: 16 mm
• Application: Newage 40M / 85M gearbox assemblies
• Function: Rotational support and low-friction shaft bearing

This bearing is commonly used within Newage Dana Spicer gearbox systems fitted to Thwaites and similar 2–3 tonne dumper platforms, including applications where the 85M gearbox is installed.

TYPICAL APPLICATIONS

Suitable for a range of machinery, including:

• Thwaites site dumpers (2–3 tonne class models)
• Benford / Terex / Mecalac dumpers with Newage gearboxes
• Newage 40M and 85M gearbox assemblies
• Transmission input/output shaft support systems
• Compact construction and material handling equipment

IMPORTANT INFORMATION

Always confirm the correct OEM part number and gearbox model before ordering, as needle bearing dimensions and configurations can vary between gearbox variants (including different Newage 85M builds and Dana Spicer derivatives). Incorrect bearing selection can lead to gearbox noise, shaft wear, overheating, or premature transmission failure.
