NHE22
These locknuts provide positive locking in applications subjected to very heavy loads, vibration, or shock environments. NHE locknuts are wider and larger in OD than our standard N or AN locknuts, but share the same thread pitch across the series.
Features and benefits
- Heavy duty fastener that shares thread pitch with standard series.
- Size range that accommodates most rigorous applications.
- Simple installation and removal.
- Standard Locknut sets the industry locknut standard
- Locknuts have four, equally spaced slots around their circumference to accommodate a hook or impact spanner.
- NHE00 locknuts are commonly used with 12, 13, 222, 223, and 232 series spherical roller bearings.
- Can be mounted directly to the shaft or via an adapter sleeve.
- NHE locknuts can be reused, provided they are not damaged. A new TW series lockwasher should be used each time the corresponding locknut is installed.
- Provide operational and installation clearances, higher installed accuracy, and lower rotating imbalance loads than hexagonal or square locknuts.
- Conform with ABMA, SAE and ABEC standards for bearing and power transmission applications.Bearing face / pitch diameter runout will not exceed .004 inches for sizes 08 through 22, and .006 inches for sizes above 22.
- Manufactured from AISI grade 1000 or 1200 series steel.
- Bearing face surface finish will not exceed 120 microinches for sizes 11-22, and 150 microinches for sizes above 22.
- Use with series TW lockwashers.
- Manufactured with ANSI K-1 Class 3 threads.
- Most suitable with rolling element bearings, cams, clutches, gears, pulleys, sprockets, and sleeve assemblies.
