This linear ball bearing carries recirculating ball sets between an inner sleeve and outer sleeve, allowing continuous linear motion along a shaft. Bore diameter is 16.0 mm, outside diameter 26.0 mm, and net mass 47.25 g. The machined design gives it defined running accuracy for guiding a shaft under linear travel. The bearing is sealed on all sides, which keeps contaminants out of the ball tracks and retains lubricant inside the unit. A relubrication facility is provided, so grease can be replenished during service without dismantling the bearing from its housing. A corrosion-resistant version of this design is possible, which is relevant where the bearing surfaces need protection against moisture exposure during operation.
