This linear ball bearing enables low-friction linear motion along a shaft, using recirculating ball tracks in a machined design. Bore diameter is 25.0 mm, outside diameter is 40.0 mm, and net mass is 0.186 kg. The bearing is adjustable and sealed on all sides. The all-side sealing protects the ball tracks from contamination while the relubrication facility allows grease to be replenished without dismantling the unit, supporting continued operation once initial lubrication is depleted. The adjustable design permits setting of internal clearance to suit the shaft fit, and the corrosion-resistant design option (AS) extends its use to environments where standard steel components would be at risk of surface corrosion.
