YSK Series - Precision Clasp Locknut

The YSK Series locknuts utilize the elasticity of the steel body itself, axial locking, and forced locking. With locking

capabilities more than three times higher compared to traditional locknuts, this series is aimed at harsh working

conditions where locknuts are easily loosened.

YSLR locknut uses steel's elasticity characteristics to securely fix the locking nut in the radial direction. This type of nut

is thinner and suited to narrow applications. The design is very simple and easy to lock. This type of nut is not suitable

for high precision requirements as it is more difficult to assure the perpendicularity of the nut at this size.

The SGL-F Series locknuts employ 30°, 3 point locking. The outstanding design of the brass threads are perfectly matched and prevent any

loosening whatsoever. 30° design locking screws also reduce torque on this product. Clamping rim, trailing rim, and outer skirt are precision

ground to conform to high precision requirements during high rpms.

The SGL-R Series Locknuts employ 3-way radial locking. Thickness is comparatively thinner than other products. This series is especially applicable for use when locknut

space is limited. Aside from where other products are not usable due to space restrictions, locknut threads, clamping rim, trailing rim, and outer skirt are precision

ground to conform to high precision requirements during high rpms.

The SGL-K Series locknuts utilize the elasticity of the steel body itself, axial locking, and forced locking.

With locking capabilities more than three times higher compared to traditional locknuts, this series is

aimed at harsh working conditions where locknuts are easily loosened. Locknut threads, clamping rim,

trailing rim, and outer skirt are precision ground to conform to high precision requirements in high rpms.

Lock screws intersect at a 30° angle. Superior to traditional locknuts with only 3 lock screws, the SBL-A employ 6 lock

screws to the axis. Perfect mesh. Precision and balanced compression. Zero loosening under any load or speed. Inner

threads, outer skirts, clamping & trailing rims are all precision ground, minimizing noise & vibration.

SBL-B Series

This design differs from the SBL-A in that there are balance adjustment screws added at the trailing surface, making

for added convenience in precision adjustment. Balance adjustment screw holes can be fitted with screw-in plugs

(option), eliminating high frequency noise and subsequent vibration.

The difference with this design is that the balance adjustment screws tighten from the outer skirt at a radial

angle. It is the optimal choice for spindles with restricted space. Balance adjustment screw holes can be fitted

with screw-in plugs (option), eliminating high frequency noise and subsequent vibration.

For spindles with exceptionally restricted or narrow space, this model is ideal in that it is super thin and

requires no additional tooling or components to do its job. For thread sizes under M45 we offer the SBL-D

with 3 lock screws, and for larger threads we offer the SBL-D with 6 lock screws. Balance adjustment

screw holes can be fitted with screw-in plugs (option), eliminating high frequency noise and subsequent

vibration.
