NTH16
These locknuts provide positive locking in applications with limited space. NTH locknuts are 25-50% thinner than our standard N or AN locknuts, and have a smaller outer diameter, but share the same thread pitch.
Features and benefits
- Thin section fastener that shares thread pitch with standard series.
- Comprehensive size range.
- 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.
- NTH00 locknuts are commonly used with 231 and 232 series spherical roller bearings.
- Can be mounted directly to the shaft or via an adapter sleeve.
- NTH locknuts can be reused, provided they are not damaged. A new lockwasher should be used each time the corresponding locknut is installed.
- Lockwashers are available for thread 0.391 to 8.628 in. (sizes 00 to 44)
- 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 .002 inches for sizes 00 through 06,.004 inches for sizes 07 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 100 microinches for sizes 00-10, 120 microinches for sizes 11-22, and 150 microinches for sizes above 22.
- Use with series WT lockwashers.
- Manufactured with ANSI Class 3 threads.
- Most suitable for machine tool, gearbox and aerospace applications with rolling element bearings, cams, clutches, gears, pulleys, sprockets, and sleeve assemblies.
