National 99157 Redi-sleeve shaft sleeve 0.25 mm 🔧
Product description
This shaft repair sleeve from National fixes grooved or worn shafts with minimal fuss and downtime. It's designed for maintenance teams and mechanics who need a corrosion-resistant, easy to fit solution, and it helps restore a clean sealing surface according to manufacturer.
Key features
The Redi-sleeve is an ultra-thin repair sleeve that lets you reuse the original seal size while adding minimal lip loading. National 99157 Redi-sleeve combines a durable sealing surface with a slim wall to avoid changing seal geometry, and the stainless steel construction reduces corrosion risk. Installation is straightforward thanks to a removable flange and a dedicated installation tool that helps cut distortion and allows fitting without removing the shaft. Practical benefits include faster repairs, less downtime, and a sealing surface that often surpasses original shaft specifications according to manufacturer. Need to address visible seal tracks or grooves quickly and reliably? This sleeve aims to do exactly that.
Tech specs
- Name: National 99157 Redi-sleeve
- Material: Stainless steel
- Type: Shaft repair sleeve
- Size: 0.25 mm wall thickness
- What’s included: Removable flange and installation tool
Who it’s for
It’s a great fit if you service rotating equipment with worn seal areas and want a corrosion resistant patch that preserves original seal dimensions, such as in pumps or gear assemblies. It may not be the best choice if the shaft has severe damage beyond surface grooves or if full replacement of the shaft is required, since the sleeve addresses wear and minor surface defects rather than structural shaft failures.
The description above mixes clear benefits with practical notes and a modest limitation, helping technicians decide quickly whether the Redi-sleeve matches their maintenance needs. 🛠️
