Hernon® Cylinlock 827 is a single-component, medium-strength anaerobic retaining compound for cylindrical joints. It cures when confined between close-fitting metal surfaces in the absence of air and allows disassembly for service, typically for retaining bearings on shafts and in housings.
Typical Properties
- Chemical type: methacrylate ester; appearance: yellow fluorescent liquid
- Specific gravity 1.08; viscosity at 25 °C: 400–800 cP
- Maximum diametral clearance: 0.18 mm (0.007 in)
- Temperature range: −55 to 177 °C (−65 to 350 °F)
Performance
- Shear strength (ISO 10123, steel pins and collars, 24 h at 22 °C): >13.8 N/mm² (>2000 psi)
- On inactive metals or for faster cure, use Hernon EF Primer 49 or 50; non-metallic surfaces need primer or heat
- Disassemble by heating to at least 260 °C (500 °F); remove cured residue with Hernon Gasket Remover 30
Directions for Use
- Clean all surfaces with Hernon cleaning solvent and allow to dry
- Slip fits: apply around the leading edge of the pin and inside the collar, assemble with a rotating motion
- Press fits: coat both surfaces; shrink fits: coat the pin and heat the collar for clearance
Storage
- 8–28 °C (46–82 °F) in unopened containers; not for pure oxygen or oxygen-rich systems
