Easy and quick bearing mounting and dismounting in SNL housings

The hook spanners of HN /SNL series are especially designed to facilitate easy and quick mounting and dismounting of bearings with tapered bore on adapter sleeve in SKF SNL bearing housings. They are also suitable for tightening and loosening a wide variety of locknuts in both housing and shaft applications. The HN /SNL series consists of 16 sizes suitable for nut outer diameter ranging from 38 to 145 mm (1.5 to 5.7 in). The spanners are made of hardened high quality chrome vanadium steel for durability.

• Unique, special design allows the HN /SNL series to be used inside SKF SNL and SNH bearing housings
• Suitable for tightening and loosening KM, KML, N, AN, KMK, KMFE and KMT lock nuts, facilitating the use in a wide range of housing and shaft applications
• The large contact area of the spanner around the nut provides excellent grip
• Exact fit reduces the risk shaft, nut and housing damage
• Designation is laser-engraved on the handle allowing easy identification and selection.
• Additional five larger sizes for nut outer diameter 155 to 210 mm (6.1 to 8.3 in) are available upon request.
• Easy storage due to hole in handle for hanging up.

Technical Data:

• Material: Black phosphated, hardened chrome vanadium steel
