Penelitian ini menganalisis respon tegangan dan deformasi pada bearing UCP 211-32 yang digunakan pada alat simulator balancing. Bearing mengalami pembebanan akibat gaya radial dan gaya unbalance yang timbul dari ketidakseimbangan massa rotor pada kecepatan 3000 rpm. Beban ekuivalen dihitung berdasarkan data katalog SKF, kemudian diterapkan pada model 3D bearing menggunakan metode Finite Element Analysis (FEA) di ANSYS Workbench. Hasil simulasi menunjukkan nilai equivalent stress maksimum sebesar 65,822 MPa dan total deformation maksimum sebesar 0,0033128 mm. Tegangan dan deformasi tersebut jauh di bawah batas izin material sebesar 250 MPa dan 0,25 mm, sehingga bearing dinyatakan aman beroperasi pada kondisi tersebut. Lokasi konsentrasi tegangan terjadi di area kontak antara inner ring dan elemen gelinding, sedangkan deformasi terbesar terletak pada inner ring akibat pembatasan gerak housing (fix support). Hasil penelitian ini dapat menjadi acuan dalam perancangan sistem berputar serta evaluasi kestabilan bearing terhadap pengaruh gaya unbalance.
