Precision Locknuts

Product Details:

Spieth is a technological leader and provider of mechanical connecting, bearing and locking solutions for drive and guide components.

Spieth connecting components are one-piece, rotationally symmetrical elements that fulfill their clamping, gripping, locking and guiding functions thanks to their elastic deformation. Axial force is applied to them to activate the function. As a result of the elements’ geometry, all elastic movements are made with maximum symmetry and take advantage of the high production quality of the Spieth components to align the connection.

Precision nuts with a high-quality locking system (premium thread-locking). Spieth locknuts with the unique Spieth principle can be set exactly to the demanding tasks in mechanical engineering with extreme precision and even clamping forces on the thread flanks.

Spieth guide bushings – round guidance and clamping with adjustable play – open up new dimensions for modern, efficient and economical machine designs with high power densities and high levels of dynamic stress thanks to the Spieth principle.

Friction-locked shaft-hub connections providing all-round pressure. They are more accurate, precise, efficient, and easier to assembly and more service-friendly thanks to the Spieth principle.

NIKKI Precision Locknuts
HSIANG KAI FU CO., LTD. is a professional manufacturer of precision locknuts for bearings and precision machine components. It was founded in 1994 and is located in The Taichung Precision Machinery Technological Park in Taiwan.
NIKKI Precision Locknuts are designed to provide adjustment, preload and secure machine components to spindle/ball-screw and other rotating machine elements. Our locknuts allow accurate setting of preload on bearings and are capable of supporting axial loads with very high rigidity without loosening.

All of NIKKI precision locknuts are produced under "High Locking", "High Precision", "High Stability" and having following advantages:

• No thrust washer or keyway needed.
• Easy to assemble and disassemble.
• Can be re-used if handled properly.

Product Range

• Best Flank Angle Locking Series - Thanks to NIKKI's design patent, the difference between the locking torque and the surface pressure of the Best Flank Angle Locking Series locknuts stays within 10%. This series effectively prevents the systems from overheating, loosening, and making noises. 
• 30˚ Flank Locking Series - The setscrews lock at a 30° radial angle in locknuts and drive the locking brass perfectly stuck on the thread flank of the shaft.
• Radial Locking Series - The setscrews lock at a radial angle in locknuts.
• Axial Locking Series - The setscrews lock at an axial angle in locknuts. The contact surface of this locknut series is all produced by grinding. Its anti-loosening capability is especially suitable for instantaneous high-speed operations.
• Mounting Tools - NIKKI provides turnkey locking solutions. NIKKI mounting tools can effectively prevent the single point of force applied to the locknuts compared with traditional tools. With NIKKI mounting tools, our clients assemble the precision locknuts more conveniently and accurately while saving the locking workforce.

Yinsh Precision Industrial Co., Ltd. was originally a family-based processing plant which produced precision component parts. It was founded in 1989 by Mr. Guo-hua Lin, the President of the company.
Precision LocknutsYinsh Precision have been dedicated to manufacturing precision locknuts for over 30 years and stand as the number one supplier in Taiwan in the sector of high precision locknuts.
1. YSPL Series Locknuts
• YSLK- YSLK locknut uses steel’s elasticity characteristics to securely fix the locknut in the axial direction. This product is especially suited to space restricted applications, or high contamination working environments where the nut could potentially become loosened more easily.• YSLR - YSLR locknut uses steel’s elasticity characteristics to securely fix the locknut in the radial direction. This type of nut is thinner and suited to more 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.• YSAM - YSAM locknut uses steel’s elasticity characteristics to securely fix the locknut in the axial direction.• YSMSW - YSMSW locknut uses steel’s elasticity characteristics to securely fix the locknut in the axial direction. This type of nut is thicker and the outer diameter is larger, making this nut suitable for heavier axial loads.• YSFT - YSFT locks the threads from a 30° angle direction with three point locks. The advantages of this design are that the brass locking threads can fully contact the male threads, thus ensuring the assembled accuracy.• YSFTA - YSFTA uses the same locking method as the YSFT locknut, but this nut has wrench holes on the radius side and back surface side, making it easy for different assembly environment requirements.• AN - Simple structure AN locknut, simultaneously machined threading and end face, ensuring minimum deviation error.
• YSRN - The square outer shape YSRN locknut features two point brass locking screws in a 90° position. Suitable for bearing seat support. Inner threads and end surfaces are simultaneously machined ensuring assembly accuracy.
2. Superfine Balanced Locknuts
• SBL-A - 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 and trailing rims are all precision ground, minimizing noise and vibration.• SBL-B - 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. • SBL-C -  Nut 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. • SBL-D - 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. • SBL-E - This model is for spindles with exceptionally restricted or narrow space, particularly where any adjustment from the trailing surface is inconvenient. Balance adjustment screw holes can be fitted with screw-in plugs(option), eliminating high frequency noise and subsequent vibration.
