Product Description

SKF 81109 TN is a single-row steel roller bearing engineered for rotating assemblies requiring reliable radial support with axial enclosure. It features a 45 mm inside diameter cylindrical bore and a 65 mm outside diameter, with a 14 mm race width made from durable steel materials.

The bearing cage is crafted from non-metallic materials to minimize internal friction and operational noise. Its closed-end design prevents ingress of contaminants and ensures lubricant retention, enhancing durability and maintenance intervals.

This bearing has a static load rating of 153 kN and a dynamic load rating of 45 kN, providing robust support for stationary and rotating loads respectively. The limiting speed of 4500 rpm makes it suitable for use in medium-speed mechanical systems such as conveyor rollers, industrial machinery shafts, gearboxes, and idler rollers.

Manufactured in Germany, the SKF 81109 TN combines precision engineering and high-quality materials to deliver dependable performance in demanding industrial, manufacturing, and material handling applications.

153 kN static load rating ensures high resistance to stationary loads. 45 kN dynamic load rating supports moderate rotating forces. Non-metallic cage reduces operational friction and noise. Closed-end design enhances contamination protection and lubrication retention.

Limiting speed of 4500 revolutions per minute suits medium-speed mechanisms. Single-row construction offers focused radial load support. Steel bearing material guarantees durability in harsh environments. Applications include conveyor rollers, gearboxes, and industrial machinery shafts.

This Roller Bearing is essential for engineers and maintenance professionals seeking reliable bearings for industrial, construction, agricultural, and manufacturing contexts. It offers a precise fit for shafts requiring cylindrical bore mounting and delivers consistent mechanical performance for smooth rotational operations.
