The 170mm inner diameter (ID) of this SKF cylindrical roller bearing ensures precise shaft fit, critical for minimizing vibration and extending equipment life. Its single-row structure balances load capacity with compact installation requirements—essential in space-constrained machinery components. The “BK” designation indicates a machined brass cage, which offers excellent heat resistance and dimensional stability compared to plastic alternatives, ensuring consistent performance in temperature-fluctuating environments.
