  Q: Can excessive motor bearing temperature burn the windings? A: It can contribute to winding damage, but high bearing temperature does not necessarily mean that the motor windings will burn out. Bearings and windings perform different functions, but they are thermally interconnected during motor operation. Excessive bearing temperature can transfer heat through the shaft, bearing housing, end shield, and internal air, increasing the overall thermal load inside the motor. If the bearing temperature is only temporarily elevated and remains within the allowable operating range, it generally will not directly damage the windings. However, if bearing overheating continues and leads to lubrication deterioration, severe wear, seizure, or bearing lock-up, the resulting mechanical resistance can increase motor load and current. If the motor protection system does not interrupt the abnormal condition in time, the windings may experience excessive thermal stress, potentially causing insula...

    As golden September arrives, Luoyang Bearing Research Institute Co., Ltd. (ZYS) embarks on a new journey of quality excellence. In strict alignment with the quality management deployments of Sinomach and Sinomach-PI, ZYS officially launched its 2026 "Quality Month" campaign. Centered on the theme "Strengthening End-to-End Quality, Championing ZYS Responsibility," the initiative calls upon every ZYS employee to embrace their roles, uphold strict quality responsibilities, and translate craftsmanship into everyday action—safeguarding the company's sustainable, high-quality development through precision workmanship across the entire value chain. Quality is never merely a slogan. It is embedded in every rigorous blueprint verification, embodied in every step of precision manufacturing, and consistently demonstrated in every detailed inspection and testing procedure. Reliable product quality relies on the steadfast dedication of every position; long-term corpora...

  A custom bearing inquiry almost always starts with a drawing specifying the Bore, Outside Diameter (OD), and Width. However, dimensional envelope alone is rarely enough to guarantee reliable performance. Unlike off-the-shelf catalog bearings, ordering custom bearings requires evaluating the component as part of an integrated dynamic system. A bearing that fits perfectly can still fail due to: · Insufficient dynamic load capacity · Thermal clearance loss after press-fit · Incompatible lubrication at operating speeds · Inadequate housing/shaft geometric tolerances 1. Application-First RFQ Strategy To prevent premature failure, transition your RFQ from a purely dimensional request to an application-driven profile. Key System Parameters to Provide: Duty Cycle: Continuous operation vs. frequent start/stop, shock loads, or peak accelerations. Operating Envelope: Continuous/max speed (RPM), ambient & operating temperatures, environmental exposure (moisture, dust, chemicals). Target ...
