The SKF H 318 Adapter Sleeve is a critical component designed to secure bearings with a tapered bore (such as spherical or self-aligning ball bearings) onto cylindrical shafts. Manufactured from high-strength, precision-machined steel, the H 318 ensures optimal concentricity and load distribution. It features a standardized 1:12 taper ratio and utilizes the pressure applied by a dedicated lock nut (KM 18) and washer (MB 18) to secure the bearing firmly in place. This mounting technique simplifies installation and dismantling, minimizing the need for specialized shaft seating or complex machining, which is essential for heavy industrial environments.
Choosing the genuine SKF H 318 guarantees maximum durability and operational security, extending the service life of associated bearings and reducing unexpected downtime. Its robust construction resists vibration and heavy shock loads common in conveyor systems, pulp and paper machinery, and mining operations. This solution is fully interchangeable with other major bearing manufacturer specifications and represents the benchmark for reliable, cost-effective mounting on unstepped shafts, ensuring quick and accurate bearing location and tight radial seating.
