THK high-precision motion solutions: Cross roller collars and cam guides 1. Cross Roller Rings THK Cross roller collars is a revolutionary thin slewing support bearing with a unique cross roller arrangement design. The rollers are arranged orthogonally and staggered at 90° in the precision-machined V-shaped raceway. Only a single set of bearings can withstand radial loads, axial loads and overturning moments at the same time, achieving the perfect unity of ultra-high rigidity and rotational accuracy.
Core technology 1. Ultra-high rigid bearing capacity - The cross-roller structure maximizes the stress area and can be 3 to 5 times more rigid than traditional bearings, greatly suppressing equipment vibration and deformation.
2. Extremely compact design - The highly integrated structure saves installation space and is especially suitable for space-limited scenarios such as robot joints and turntables.
3. Micrometer rotation accuracy - The grinding accuracy of the raceway reaches μm level, and it is combined with pre-pressing adjustment technology to ensure repeated positioning accuracy within ±0.001°.
4. Smooth gap-free motion - Precise pre-tightening eliminates axial/radial clearance, achieves smooth rotation with zero back clearance, and improves the dynamic response performance of the equipment.
5. Long life and high reliability - THK's patented heat treatment process and ultra-clean steel quality significantly extend fatigue life (L10 life reaches tens of thousands of hours). 2. Cam Followers THK cam guides are rolling contact followers specially designed for cam mechanisms and track systems. Its core consists of a highly rigid outer ring, precision needle rollers/rollers and a high-strength mandrel. It can transform the contour motion of the cam into precise linear or oscillating output. It is the core transmission component of automated machinery.
Core technology 1. Wear resistant and impact resistant design - The outer ring is made of carburized steel or special stainless steel, with a surface hardness of HRC 58~64, and it is resistant to high-frequency impact and wear.
2. Low friction and high response - Optimize the roller profile to reduce edge stress and reduce the friction coefficient by 40%, ensuring no lag in the motion trajectory at high speeds.
3. Integrated sealing and dustproof - Integrated double-lip seal ring + dust cover design (IP54 protection) to resist the intrusion of debris and coolant and adapt to harsh working conditions.
4. Modular installation compatibility - Various installation forms such as thread type, handle type, and eccentric sleeve are available to support quick replacement and fine adjustment of pre-tightening force.
5. Silent operation technology - Roller logarithmic curve modification technology effectively reduces vibration noise and meets clean room and medical equipment requirements.
