Product Series: Neovert Integrated Bearing Unit
The Neovert Integrated Bearing Unit for Seeder represents a significant advancement in agricultural seeding technology. Designed as a direct replacement for traditional single-row deep groove ball bearings, this double-row angular contact integrated unit delivers superior load capacity, enhanced sealing performance, and simplified installation for modern seeding equipment.
This innovative bearing solution was developed to address the demanding performance requirements of high-speed seeders, particularly for applications requiring stable seeding disc rotation under both radial and axial loads. The Neovert Integrated Bearing Unit is engineered to improve operational efficiency, reduce downtime, and provide OEM-quality reliability at a competitive cost.
MTWB, leveraging over 18 years of bearing manufacturing experience and serving 100+ OEM customers worldwide, offers this customized solution for agricultural machinery manufacturers and aftermarket users seeking to upgrade their seeder performance.
The double-row angular contact design enables the bearing to withstand both radial and axial loads, resulting in more stable seeding disc rotation compared to conventional single-row solutions. This enhanced load handling capacity translates to improved seeding accuracy and longer component life.
The Neovert Integrated Bearing Unit eliminates the need for press-fitting installation. Instead, it connects via bolts, which:
Improves installation efficiency by up to 70%
Prevents bearing damage commonly caused by improper press-fitting
Simplifies field maintenance and replacement procedures
The unit features an increased air outlet size – expanded from the original 30.5mm to 38mm – enhancing air pressure and improving overall system performance.
With multi-lip labyrinth seal design, the bearing effectively prevents the ingress of dust, soil, and moisture – common challenges in agricultural environments. The sealing system maintains grease purity even under muddy conditions, with proven performance in rigorous field testing.
The integrated unit design incorporates a maintenance-free structure that eliminates the need for additional lubrication during service life, significantly reducing maintenance costs and operator intervention.
