ZF 635501936 – Roller Bearing 75×140×40 mm for ZF Marine Transmissions

The ZF 635501936 Roller Bearing is a heavy-duty component designed for marine propulsion systems and ZF transmission gearboxes. With a size of 75×140×40 mm, it supports both radial and axial loads in high-load, high-speed environments. Manufactured from high-strength SAE 52100 bearing steel, it delivers excellent wear resistance, low friction, and long operational life, even in harsh saltwater conditions. The open-type design ensures efficient lubrication and heat dissipation, with compatibility for both oil and grease-based systems.

Key Features:

Robust roller bearing design for radial and axial load support
Made from heat-treated SAE 52100 bearing steel
Dynamic load capacity: 130 kN
Static load capacity: 105 kN
Open design allows direct access for oil or grease lubrication
Low-friction operation reduces energy loss and component wear
Corrosion-resistant construction for marine environments
High-speed performance with C3 radial clearance
Operating temperature: -40°C to +150°C
