Ball Screw Support Bearings - BSF Series
The BSF series of bearings is equivalent to the BSN range of bearings, with an extended outer ring, with bolt holes for easy direct mounting. Relubrication holes in outside surface and face of the outer ring allow for relubrication during operation if necessary. The holes are closed off with set screws. An extraction groove on the outer surface of the outer ring aids removal of the bearing.
BSF-DT Series
The matched DT pairs are essentially the same as the individual bearings. The two individual bearings have been matched together in the paired version. Some sizes also have extra fixing holes in the outer diameter. Both bearings have a V-shaped mark on the outer diameter to ensure that they are arranged correctly.
Features and Benefits
• 60° Contact angle enabling the bearings to support large axial forces
• Double row to support axial force in two directions
• Contact lip seal provides excellent sealing with low friction and heat generation
• Greased for life (under normal operating conditions)
• Easy mounting directly onto machinery
• Extraction groove to aid with removal
• Set screws
Product Application Information
Ideal for use in machine tools.
