Single-row deep groove ball bearings with seals or shields on one or both sides are particularly versatile, offering low friction and optimized performance for low noise, low vibration, and high rotational speeds. They can accommodate both radial and axial loads in both directions, making them suitable for a wide range of applications. These bearings are easy to mount and require less maintenance than many other types. The integral sealing system significantly prolongs bearing service life by keeping lubricant within the bearing and keeping out dust.

    Our Story:
    We are a family-owned and family-operated business. We have been in the business since 1979. Our founder, now a grandfather to many grandchildren, started over 40 years ago by selling combine harvester parts, which is regarded as a factory on four wheels. A combine harvester includes all types of parts such as bearings, flanges, oil seals, snap rings, roller chains, sprockets, V-belts, pullies, spring tins, and many other parts.
    The father trusted his sons to take over the business, and with his support and encouragement, they expanded the business, from combine harvester parts to the same parts across all other industries, such as . The sons gained more experience, moved to different parts of the world, and were able to establish their business in North America, Europe and Asia.
