      abstract = {Bearing production lines combine high-speed rotating machinery, machining, heat treatment, grinding, cleaning, assembly, inspection, packaging, warehousing, and maintenance. These interconnected tasks generate cumulative risks, including entanglement, pinch points, flying particles, burns, chemical exposure, noise, ergonomic strain, and hazardous energy release during intervention. This paper develops a structured process-safety framework for bearing manufacturing. The framework integrates task-level hazard identification, layered machine safeguarding, safe mounting and dismounting workflow design, ergonomic material handling, and lockout/tagout control for maintenance. It is organized around representative production stages and aligned with established principles of occupational safety, machinery protection, risk reduction at source, guarding, interlocking, safety-related control functions, and verified energy isolation. Evidence from machine-guarding practice, lockout/tagout auditing, participatory safety management, and job safety analysis informs the proposed control logic. The resulting hazard map identifies key risk points across raw-material receiving, turning, heat treatment, grinding, cleaning, assembly, inspection, packaging, and warehouse operations. The safeguarding architecture combines inherent risk reduction, fixed guards, interlocked access points, presence-sensing devices, emergency stop functions, controlled energy isolation, safe work procedures, training, supervision, and inspection. Safe mounting, dismounting, and maintenance workflows are designed to reduce exposure to nip points, unexpected start-up, stored energy, and unstable components. Bearing production-line safety can be strengthened by integrating process hazard mapping, machine safeguarding, ergonomic handling, and rigorous lockout/tagout into a unified layered control system. The framework provides a practical basis for plant-specific safety programs in discrete manufacturing environments. It also supports continuous improvement through audits, worker feedback, and periodic verification of control effectiveness},
