Welding Robot (100-0032 to 4519-026) Parts List

OTC DAIHEN Robot General Basic Standard Parts and Mechanical Lubrication Spare Parts Overview

Industrial welding robots perform high-speed, high dynamic trajectory interpolation and long-term uninterrupted operations in fully automated production lines. To support their high-load mechanical output and ensure high-precision motion stability, strict bottom-level foundation spare parts inspection and consumable supply specifications must be established. This not only involves various overcurrent protection consumables inside the control cabinet (such as micro fuses, air circuit breakers, surge absorbers), but also includes the sealing, support of the mechanical arm body transmission chamber, and the lubrication management of the joint reducer.

To assist factory automation maintenance supervisors and spare parts procurement teams in efficiently targeting official original codes, we have comprehensively compiled a general spare parts catalog for the OTC welding robot electromechanical system. The model range on this page covers 100-0032 to 4519-026. This section highlights core components such as dedicated grease for joint RV/harmonic reducers (e.g., VIGOGREASE RE0, FZ No.00 series), rigid support bearings and sealing rings (e.g., 3311-208, 3574-007, 100-0913), built-in overcurrent protection and filter components in the control cabinet (e.g., 4610-069, 100-1743, 4519-026), as well as fundamental key parts like human-machine interactive touch components and high-sensitivity limit/stroke micro switches (e.g., 4254-120, 100-3636, 100-1649).

Preventive Maintenance Guide for Core Standard Parts and Joint Grease

• ▶ Periodic Grease Replacement Specifications for Dedicated Reducer Grease (e.g., 100-0624, 100-0127): The RV reducers and high-precision gearboxes of the robot’s axis 1 to axis 6 withstand tremendous mechanical shear stress. The official grease change hours specification (usually 10,000 working hours or maintenance cycle reached) must be strictly followed, and it is mandatory to inject the officially designated VIGOGREASE RE0 or FZ No.00 grease. Never inject inferior or incompatible ordinary industrial yellow grease; otherwise, it will easily accelerate early mechanical fatigue wear of the cycloidal pinwheel and harmonic gear teeth, leading to enlarged joint backlash or even seizing.
• ▶ Leakage Prevention Management for Fluid Pipelines and Dynamic/Static Sealing Surfaces (e.g., 3574-007, 3572-012, 100-0913): Various specifications of O-rings and skeleton oil seals (such as P12, P10 Viton fluororubber rings) are widely distributed at the output shaft end of the robot servo motor, the connection surface of the reducer, and the inside of the water-cooling/gas circuit pipeline quick connector. After enduring high-temperature radiation and work deformation in the workshop for a long time, the rubber is prone to thermal hardening and shrinkage, causing grease leakage or gas-water leakage. If oil seepage is found in the motor junction box during inspection, a high-quality wear-resistant fluororubber ring of the corresponding model should be matched and quickly replaced immediately.
• ▶ Electrical Circuit Overcurrent Interlock and Safety Limit Protection (e.g., 4610-069, 4250-125, 4254-120): Due to the strong arc radiation and potential risks of physical mechanical interference at industrial welding sites, all levels of fuses (such as GP100, FGMB series) inside the control cabinet and the main incoming automatic circuit breaker (such as NF63-CV series) constitute an electrical protection wall. The high-reliability limit switches and emergency stop buttons installed at the mechanical limit ends of the axes are lifelines to prevent mechanical collision over-travel. During inspection, the switch contact rebound sensitivity should be regularly checked to ensure instantaneous safe locking in the event of sudden interference.

Why Stick to Official Original Imported OTC DAIHEN Standard Parts on Automated Industrial Production Lines?

The automatic arc welding workstation belongs to a typical harsh industrial environment with all-weather, heavy overload, and high variable frequency crosstalk. The use of any non-compliant substandard mechanical lubricants or small micro-electrical standard parts will plant a major production safety hazard—for example, incorrectly filling ordinary industrial yellow grease (not officially designated VIGOGREASE RE0), it is extremely easy to cause shear failure and overheating during the high dynamic rotation of the joint axis, directly leading to early tooth surface spalling and severe backlash deterioration of the high-rigidity reducer. Furthermore, the use of inferior non-original glass tube fuses, ordinary film capacitors without high-frequency absorption characteristics, or ordinary sealing rings not made of fluororubber materials can easily cause high-frequency arc pulses to break down the main CPU board, oil leakage due to aging of the sealing surface to burn the motor encoder, or cause the robot to drift over-travel due to the failure of the limit switch, resulting in serious collision damage. We promise that all original reducer grease, crossed roller bearings, control cabinet high breaking capacity air circuit breakers, ultra-fast acting fuses, and limit switches we supply are 100% Brand New Official Original Genuine Products.
