Product Description

SKF 81210 TN Roller Bearing with a 50 mm inside diameter and 78 mm outside diameter is a precision single-row cylindrical bore bearing designed for robust industrial use. Constructed primarily of steel for high contact fatigue strength, this bearing features a closed end and a non-metallic cage to reduce friction and protect internal rolling elements from contamination.

Its static load rating of 300 kN ensures capacity to sustain heavy stationary loads, while a dynamic load rating of 91.5 kN supports continuous rotating applications. The bearing is engineered to operate safely up to a limiting speed of 3400 rpm, making it suitable for moderate-speed conveyors, gearboxes, pump drives, and various machine tool spindles.

The bearing's cylindrical bore mandates precise mounting on straight shaft journals with correct interference or transition fits to ensure positional stability during operation. The closed end design aids in maintenance by retaining internal components and simplifying visual inspections.

Steel races and rollers provide excellent fatigue resistance under both static and dynamic load conditions. The non-metallic cage further enhances bearing life by reducing internal wear and friction losses. With a single-row design, axial alignment requirements are minimized, easing installation and maintenance.

This product is ideal for heavy-duty industrial drive shafts and conveyor rollers in material handling setups. It is also well suited for gearbox intermediate shafts requiring high static load capacity. Use in pump drives and machine tools with cylindrical mounting is recommended where moderate rotational speeds are involved.

Manufactured in Germany, it adheres to stringent quality controls for reliable performance.

For engineering or machine design projects requiring reliable roller bearings, browse the SKF 81210 TN and related products in the Roller Bearing category on EnvMart for quality and performance assured components.
