RA Thin Cross Roller Bearing

Ang serye ng RA na thin-profile crossed roller bearings ay nagtatampok ng mas maliit na panlabas na diameter at lapad na sukat, na ginagawang angkop ang mga ito para sa mga application na limitado sa espasyo. Available ang seryeng ito sa mga uri ng cage, separator, at full complement upang umangkop sa iba't ibang pangangailangan.

Load Capacity:
Pangunahing Dynamic Load Rating (Ca): 234,000 N
Pangunahing Axial Static Load Rating (C0a): 690,000 N
Pangunahing Axial Dynamic Load Rating (Cr): 166,000 N
Pangunahing Radial Static Load Rating (C0r): 340,000 N

Mga Tampok ng Bearing:
1. Napakahusay na Rotational Accuracy: Mataas na bilis ng kakayahan, na makatiis ng malalaking axial at radial load.
2. Madaling Pag-install: Nakakatipid ng espasyo sa pag-install, binabawasan ang haba ng baras at mga gastos sa machining.
3. Mababang Thermal Expansion: Minimal na mga pagbabago sa dimensyon, na angkop para sa mga high-precision na application.
4. Mababang Panimulang Torque: Binabawasan ng mga naylon separator ang rotational inertia at pinapadali ang angular indexing control.
5. Mataas na tigas at katumpakan: Pinahuhusay ng na-optimize na preload ang higpit at katumpakan ng pagpapatakbo ng roller.
6. Wear at corrosion resistance: Binuo gamit ang high-carbon chromium steel (GCr15) at TN engineering plastics, na nagbibigay ng mahusay na impact resistance at surface wear resistance.

Mga Application:
Ang RA series crossed roller bearings ay malawakang ginagamit sa robot hand rotary joints, precision testing instruments, direct-drive torque motors, high-precision turntables, at iba pang application na nangangailangan ng mataas na precision at rigidity.
