Mounted Linear Ball Bearings NB Steady state speeds to 60 in./sec. Operating temp. range: -4? to 176?F Flanged bearings do not require a housing, which allows them to maintain a low-profile for use in tight spaces. Precision-ground raceway surface and precision ball elements assure low friction and smooth running while maintaining a high load capacity and excellent moment load capacity. This listing is for each. Technical Specification Item Linear Square Flange Mount Bearing Type Closed, Double Length Bore Dia.
