Ningbo Kent Bearing Co., Ltd

              During the complete motor test, bearing noise always stays at the critical point between "qualified" and "excellent". Even though standard parts from top international brands are selected, the temperature rise and vibration data remain unstable after assembly.               Do not let "general standards" restrict your product performance. For motor manufacturers pursuing ultimate energy efficiency and silent performance, the real competitiveness often lies in overlooked OEM customization details.   Ningbo Kent Bearing improves efficiency through automated production lines, controls quality via precision inspection, and benchmarks international requirements with dual standards. It delivers stable performance of "high precision, low noise, long service life". As a preferred supplier of medium and high-end motor bearings, we have provided more than 200 million sets of motor bearing solutions for over 500 motor manufacturers worldwide. Today we will discuss the practical modification requirements that motor manufacturers can propose to bearing suppliers, which can be implemented and bring performance premium. Tailored clearance and fit: Abandon the rough selection of C3/C4. Require suppliers to provide μm-level customized clearance range according to the thermal expansion coefficient of the motor shaft system, interference value and operating temperature, so as to solve the seizure or abnormal noise issues under high-speed operation. Scenario-based adaptation of cage materials: For high-frequency insulation requirements of variable frequency motors, customize cages made of engineering plastics such as PEEK/PTFE. For heavy-load starting conditions, optimize the pocket shape and rivet process of brass cages instead of simply changing materials. Formula-level coordination of grease: Reject the default grease provided by suppliers. Based on the motor speed-temperature curve, jointly develop or specify base oil viscosity, thickener type and additive ratio to achieve the optimal balance between service life and low noise. Non-standard design of sealing structure: For special working conditions such as dust and moisture, customize lip contact pressure, labyrinth structure or special coating to improve protection grade without increasing friction torque.   Bearing customization is more than simply putting forward requirements. It requires suppliers to have profound application engineering capability and flexible production line support. If you are troubled by noise, service life or temperature rise issues of motor bearings, and struggle to find a partner who can understand your requirements and implement them effectively, please contact the Kent technical service team at 19957451956. We will help you quickly locate the root cause of problems, easily resolve motor failures, reduce after-sales losses and retain core customers steadily!

Many purchasers and maintenance technicians assume that stainless steel bearings will never rust once selected. In their understanding, stainless steel, as the name suggests, does not rust and can fully resist water, moisture and corrosion.                                     However, many users encounter pitfalls in practical applications. Even with stainless steel bearings, rust spots and dark marks appear on the surface soon. Pitting corrosion, rotation jamming may occur, and the bearings eventually wear out and fail. Is this a product quality issue, or a result of cutting corners by suppliers?     The answer is straightforward. We misunderstood the meaning of "stainless steel" from the start. Stainless does not mean rust-proof forever.     The rust resistance of stainless steel bearings relies on a dense passive film on the surface. This protective film isolates moisture and air, and can basically prevent rust in dry indoor environments. Nevertheless, the passive film is not robust. When exposed to accumulated water, salts, acids and alkalis, especially chloride ions, the protective film will be damaged rapidly.     Corrosion caused by chloride ions features strong permeability. It does not only stay on the surface but penetrates deep into the metal and forms pitting corrosion. At the initial stage, only tiny dark spots appear, which are hard to detect. As corrosion worsens, bearing precision drops, abnormal noise and jamming occur, and the failure will disrupt the normal operation of the whole equipment.   Selecting bearings based solely on price is a major misconception when using stainless steel bearings. Different working conditions require completely different materials; there is no universal grade. • 201 / 304 stainless steel bearings: Suitable for conventional scenarios with dry indoor environment, no corrosion and no salt, featuring excellent cost performance to meet basic rust prevention requirements. • 316 stainless steel bearings: With stronger resistance to salt and chloride ions, they are suitable for mildly corrosive environments such as outdoor humid conditions, rain wash and food processing. Even if 316 material is selected, it can only delay rusting and cannot completely eliminate corrosion. Under extreme working conditions such as seawater immersion, high salt, high acid and alkali, and heavy chemical corrosion, the passive film of all types of stainless steel will keep failing, and corrosion problems still exist. The final selection guide is as follows to avoid unnecessary costs. • Dry indoor and conventional working conditions: Choose 304 stainless steel bearings for cost-effectiveness;       • Outdoor humid, light salt spray and food industry applications: Choose 316 stainless steel bearings for enhanced corrosion resistance;       • Seawater immersion, high salt, high acid & alkali and heavy corrosion working conditions: Select full ceramic bearings for a permanent solution.           KENT Stainless steel is only rust-resistant, not absolutely rust-free. Properly distinguishing material properties and selecting bearings accurately according to on-site working conditions can avoid corrosion problems from the source and reduce extra losses caused by equipment maintenance and downtime.
