INA KH20 Relubricatable Closed Linear Ball Bushing 20x28x30mm

INA KH Linear Ball Bearings: These compact range linear ball bearings have a small radial design envelope and are particularly economical. The low radial section height makes them ideal for applications in which only a small amount of radial space is available. KH linear ball bearings have a closed design, making them suitable for use on shafts. The bearings are maintenance-free for many applications due to the initial greasing with high-quality grease. If necessary, they can be re-lubricated via the openings in the outer ring. Bearings and housings of this product range can be used at operating temperatures from -30 deg C to +80 deg C.
Benefits: Economical, maintenance-free, re-lubricatable, suitable for applications with a small amount of available radial space.
