Rimao is a dedicated manufacturer and bulk supplier of agricultural machinery bearings. Our bearings are engineered to withstand harsh working environments such as mud, dust, moisture, and variable loads in fields. We provide solutions for tractors, harvesters, seeders, disc harrows, balers, and other farm equipment. Rimao supports OEM production, bulk supply, and long-term cooperation with agricultural machinery manufacturers and distributors worldwide.

What Are Agricultural Bearings?

Agricultural bearings are specially designed components that support rotational motion and load-bearing in farming equipment. Compared to standard bearings, they offer increased sealing performance, corrosion resistance, and shock absorption. Agricultural bearings typically operate under dirty, wet, or abrasive conditions, making them essential to the durability and reliability of farm machinery.

Types of Agricultural Bearings We Offer

Insert Bearings with Triple Lip Seals

Designed for extreme sealing, these bearings resist dust, water, and fertilizer exposure. Commonly used in disc harrows and tillers.

Square and Round Bore Bearings

Customized for installation in agricultural hubs and flanges. Square bore bearings are ideal for non-rotating shafts, commonly seen in seeders and planters.

Disc Harrow Bearings

These bearings are heavy-duty and sealed against contamination. Suitable for working in muddy or abrasive soil conditions.

Flanged Units and Pillow Block Bearings

Integrated with housing and seals, ready for mounting in machinery frames. Used in combines, balers, and fertilizer spreaders.
