Product Description
NSK BSF2068DDUHP2B R BE4L5 2 Row Ball Screw Support Bearing with 20 mm inside diameter, 68 mm outside diameter, and 28 mm race width is designed for robust support in machine tool applications. It features a steel cage and steel balls sealed for protection and long service life.
The bearing has a 60° contact angle permitting it to withstand significant axial forces, with a double row configuration allowing it to handle forces in both directions. Its contact lip seal reduces friction and heat generation, optimizing operating efficiency.
Manufactured with a parallel bore and flanged race type, the bearing series BSF provides an extended outer ring with bolt holes for direct mounting. Relubrication can be performed through holes on the outer ring surface, which are closed with set screws when not in use. An extraction groove facilitates bearing removal during maintenance.
The bearing is greased for life under normal conditions, minimizing maintenance requirements and ensuring reliable performance over time. The 60° contact angle enables the bearing to support large axial forces effectively.
Double row design supports axial loads bidirectionally for enhanced application versatility. Contact lip seal provides superior sealing with minimal friction and heat. Bolted extended outer ring allows direct mounting and easy installation.
Relubrication holes accessible for in-operation maintenance if necessary. Set screws secure the bearing and extraction groove aids in removal for servicing. Ideal for use in precision machine tools and related industrial machinery.
This bearing is made in the United Kingdom, ensuring quality manufacturing standards suitable for industrial, manufacturing, and engineering facilities. Explore more bearings and rotary bearing solutions in the NSK range on EnvMart for reliable, precision components.
