How to Grease Roller Bearings？ 1. Cleaning Remove old grease with a mild solvent (e.g., mineral spirits) and a soft brush—this avoids mixing contaminated old grease with new lubricant, which would degrade performance. Deep-clean all bearing components: Focus on rollers, the cage, and raceways, as these areas easily trap dirt that causes premature wear. Air-dry parts completely: Never use heat sources (e.g., hair dryers), as high heat may damage bearing materials. 2. Grease Selection & Application Choose grease by operating conditions: Use lithium-based grease for high speeds, calcium-based grease for water exposure, and formulas with EP (Extreme Pressure) additives for heavy loads. Check base oil viscosity: Ensure specs (e.g., cSt @ 40°C/100°C) match the bearing’s working temperature—this guarantees effective lubrication. Control filling volume: Use a grease gun or syringe to pack grease, filling only 25–35% of the bearing’s internal space (overfilling causes heat buildup). Distribute grease evenly: Rotate the bearing slowly 2–3 times after packing to coat all moving surfaces.   3. Reassembly & Check Wipe excess grease: Use a lint-free cloth to remove exterior grease—leftover grease attracts dust and debris. Reassemble properly: If disassembled, follow the manufacturer’s instructions (pay attention to fastener torque requirements) to avoid misalignment. Test rotation: Spin the bearing by hand—it should rotate freely with no unusual noise or resistance. Pair with GQZ Bearings GQZ roller bearings are designed to enhance greasing effectiveness. Their precision-machined races and cages keep grease evenly distributed, while corrosion-resistant materials handle harsh environments. Compatible with lithium and synthetic greases, GQZ bearings suit heavy-duty applications (e.g., industrial machinery, automotive systems), extending equipment lifespan and reducing downtime.        

Roller bearings, with their high load capacity and low friction, are the backbone of modern industry. Here’s a concise guide to their applications, technical features, and how GQZ Bearing delivers tailored solutions.   1. Core Application Areas​ ·Automotive Industry​ Transmissions: Needle roller bearings are preferred for their compact design and high radial load capacity.​ Wheel Hubs: Tapered roller bearings support vehicle weight while enabling smooth wheel rotation.​   ·Industrial Machinery Conveyor Systems: apered roller bearings handle both radial loads (from material weight) and axial thrusts, ensuring stable and low-friction material transport. Gearboxes: Spherical roller bearings handle radial/axial loads and shaft misalignment with self-aligning capabilities.   ·Specialized Fields Medical Equipment: High-precision bearings ensure stability in MRI and CT machines. Aerospace: Needle bearings’ lightweight design meets aircraft requirements for space efficiency.   2.Bearing Types & Technical Features​ Cylindrical Roller Bearings: Ideal for high-speed, high-radial-load scenarios like motors.​ Tapered Roller Bearings: Handle combined radial/axial loads, widely used in automotive axles.​ Spherical Roller Bearings: Self-aligning design compensates for installation errors, suitable for mining machinery.​ Needle Roller Bearings: Ultra-thin profile saves space in gearboxes and hydraulic pumps.   GQZ Bearing: Professional Manufacturing & Customization Wuxi Guangqiang Bearing Trade Co Ltd specializes in producing high-quality bearings with full model coverage and competitive pricing:​ Product Advantages: ISO-certified, premium bearing steel ensures low noise and long lifespan.​ Inventory & Logistics: Three warehouses stock ready-to-ship products, delivered via DHL/UPS within 5-7 business days.​ OEM Services: Customized solutions from material selection to structural design are available via dedicated R&D teams.​     For high-quality bearings at favorable prices, GQZ Bearing offers tailored solutions to streamline your procurement process.

Yekaterinburg, 1 July 2025 - Wuxi Guangqiang Bearing Co., Ltd (Booth No. 1S1) will bring its core products to the INNOPROM International Industrial Exhibition in Russia, which will be held from 7 to 10 July. As a representative enterprise of China's bearing industry, this exhibition aims to expand the Eurasian market, focusing on seven types of tapered roller bearings and other high-performance product lines. As an industrial platform supported by the Ministry of Industry and Trade of the Russian Federation, INNOPROM is expected to attract more than 76% of purchasing decision makers to the show. Guangqiang Bearing will demonstrate its self-developed bearing solutions on site, highlighting the stability advantages of its products under heavy load and shock load conditions. The company's head of foreign trade said: "The Russian market demand for precision mechanical components continues to grow, our inch series products have achieved international interchangeability, can accurately match the local industrial standards. During the exhibition, the enterprise will also participate in the "digital manufacturing" theme forum, and the Russian side to discuss the application of bearing technology in intelligent factories. Visitors can make an appointment for technical discussions and obtain bilingual product brochures by emailing [gq@gqbearing.com].  

The use of imported bearings features: first they are designed and manufactured on the basis of the combination system, there are very many motor combinations and installation forms, transmission ratios of each level are very fine, can meet different use cases. Secondly, they adopt the modular design principle of unit structure, which greatly reduces the types of parts and inventory. Thirdly their transmission efficiency is very high, the precision is very accurate, low energy consumption, can save energy, good performance is not easy to fail, improve work efficiency. Fourthly it has a reinforced high rigidity iron injection moulded case, and the gears are also made of better alloy steel. The surface is processed by carburising sudden fire hardening, and the grinding teeth are finely processed. Therefore, the transmission is reliable and smooth, large carrying capacity, it is the use of computer repair technology, gear repair, greatly improving the bearing capacity of the reducer, more impact resistance, low temperature rise, less failure, prolong service life.

The most influential exhibition in Wuxi   There are almost about 1000 bearing companys attending this exhibition from Wuix,Shandong,Zhangjia Gang and so on.We bring our customers to visit our factory bearings.  Havinga good communication with local bearing suppliers  expandes our sales range and enriches our bearing type to meet our customers more needs.
