687-2RS Sealed Miniature Bearing 7×14×5mm

The 687-2RS sealed miniature bearing, 7×14×5mm, is the "powerful leader" in the field of small bearings. The double-sealed (2RS) structure is like a solid protective armor, effectively isolating dust, moisture and impurities. Even in a damp and dusty harsh environment, it can ensure the smooth operation of the precision components inside the bearing. With its compact size of 7×14×5mm, it can easily fit various devices with limited space. It is made of high-quality steel of the same quality as stainless steel bearings, featuring excellent wear resistance and corrosion resistance. As a member of the Ball bearing family, it combines the classic structure of deep groove ball bearings, featuring low friction and noise during operation. If you have special specification requirements, our non-standard bearing customization service can also be tailored to your needs. In equipment such as water pumps, they can withstand pressure stably just like reliable water pump bearings, making them an ideal choice for precision instruments and small machinery.

Stainless steel bearing, with special stainless steel material and fine craftsmanship, remains as solid as a rock in corrosive environments such as dampness, acid and alkali. Whether it is the cleaning operation of food processing equipment or the continuous operation of chemical equipment, it can be stable for a long time and is not afraid of erosion. ​

Ball bearing, with the design of high-precision spheres as the core, realizes the characteristics of efficient transmission, low friction and high rotational speed, making it the "power heart" of automated production lines and precision instruments, accurately transmitting every bit of power to ensure the efficient operation of equipment. ​

Deep groove ball bearing, with its classic deep groove structure, endows it with strong radial and axial load-bearing capacity. Even under high-speed operation and complex load conditions, it still operates smoothly with low noise. It is widely used in equipment such as motors and pumps and is a reliable partner in industrial production. ​

For Non-standard bearing, we are well aware that each project has unique requirements. Our professional team customizes exclusive bearings based on the customer's equipment parameters and usage scenarios. From special dimensions to specific performance requirements, we can precisely meet them, providing a solid guarantee for your personalized projects. ​

Small bearing, though compact in size, contains great energy. With precise manufacturing processes, it achieves efficient operation within a limited space and is suitable for fields with extremely high requirements for space and precision, such as medical equipment and electronic instruments, driving precise operation with a tiny body. ​

Water pump bearing, specially designed for water pump equipment, can stably withstand water pressure fluctuations and mechanical vibrations. Even during long-term continuous operation, it can ensure the efficient operation of the water pump. It is the best choice for scenarios such as water supply and drainage systems and water conservancy projects. ​

From basic applications to special requirements, from standard products to customized solutions, our full range of main bearing products always safeguard the operation of your machinery with outstanding quality and professional services, and help equipment in various industries move forward steadily.
