Square Flanged Linear Ball Bearings
Square Flanged Linear Ball Bearings from PBC Linear® featuring a standard-sized square flange at one end for secure end-mounting, while delivering smooth, precise linear motion with a low coefficient of friction. Equipped with a heat-treated alloy steel shell, steel balls, and a polymer cage, these bearings include a resin retainer for reduced noise and double seals for enhanced durability. Available in Metric and JIS sizing with ID sizes from 8 mm to 50 mm, they offer static load capacities up to 7,900 N (1,700 lb) and dynamic load capacities up to 3,800 N (850 lb). Size interchangeable with industry standards and the Simplicity® series, they support multi-directional loading and operate reliably from -4°F to 176°F (-20°C to 80°C). Cantilevered loads are managed more effectively by linear ball bearings compared to linear plain bearings because of the 2:1 binding rule. If this rule applies, these ball bearings are ideal for advanced machinery requiring high-speed, low-friction performance.
