30209 MTM 45x85x20.75 Tapered Roller Bearing

Industrial application and working environment

The 30209 MTM tapered roller bearing in size 45x85x20.75 is designed for demanding industrial applications where combined radial and axial loads occur. It is widely used in gearboxes, hubs, conveyors, and heavy-duty machinery.

In real maintenance environments, this bearing often operates together with sealing components such as oring, rubber gasket, or sealing ring. These elements create an effective technical sealing system that protects against contamination and lubricant loss.

It performs reliably in harsh environments exposed to dust, moisture, and temperature variations, where high resistance and operational stability are critical.

Material parameters and technical properties

The 30209 MTM bearing is manufactured from high-quality bearing steel with excellent hardness and wear resistance. Its tapered design ensures optimal load distribution and reduces friction under heavy loads.

Key features:

• size: 45x85x20.75
• tapered design for combined loads
• high resistance to wear and fatigue
• stable operation at higher speeds
• compatible with sealing systems for hydraulics and pneumatics

When combined with components like oring or sealing ring, it forms a complete technical sealing solution that increases system durability.

Why this type of sealing solution is optimal

The 30209 MTM tapered roller bearing is engineered to handle both radial and axial forces, making it an optimal solution for industrial systems.

When used with a rubber gasket or oring, it enables effective static sealing, preventing grease leakage and contamination ingress. This significantly extends bearing life and reduces maintenance frequency.

Key advantages:

• extended service life
• reduced downtime
• reliable operation in demanding conditions
• improved system efficiency

This makes it ideal for industrial applications requiring durable sealing systems in hydraulic and pneumatic environments.
