Disc Bearings Round Bore Flanged

Disc Bearings Round Bore Flanged
ISUTAMI RFD round flange disc harrow bearing is an important agricultural machinery bearing installed inside the disc harrow, which is a core component in the agricultural machinery. The bearing is mainly composed of a rolling ball bearing and a dust-proof member. The ball is made of bearing steel and is mounted in a retainer to connect the inner and outer rings. Disc harrow bearings must be able to meet long-term working requirements in dusty, humid environments, and can withstand large loads in the radial and axial directions, which is another requirement for arable land operations. ISUTAMI disc harrow bearing has a multi-lip contact sealing structure to prevent dust; the bearing material contains chromium, which promotes the hardening of the bearing surface, so that the bearing has a higher load carrying capacity, and the surface of the product is treated with anti-corrosion treatment. All RFD round flange disc harrow bearings are shown in inches. The outer ring of this series has a round flange located in the middle of the bearing. Four holes are evenly distributed in the flange for fixing and mounting the bearing in the disc harrow.

Disc Bearings Round Bore Flanged Feature

The inner bore of RFD round flange disc harrow bearing is divided into two types: square and round. The mounting holes on the flange are also divided into square and round shapes. The bearing of model 5 is a circular inner ring with a diameter (d) of 1.6845''. The length of the bearing (Bi) is 6'', the hole spacing (D) of the two opposite positions is 5'', the hole diameter (E) is 0.531'', and the diameter of the bearing body (B, except the flange) is 3.865''. The model 6 bearing is a square inner ring with a diameter (A/d) of 1.6845'' or 2.0078''. The length of the bearing (Bi) is 6'' or 7.559'', the hole spacing (D) of the two opposite positions is 5'' or 5.5'', and the square hole length (G) on the flange is 0.531'' or 0.59'', the diameter of the bearing body (B, except the flange) is 3.865''. The RFD round flange disc harrow bearing adopts a 5-lip contact seal structure, and the sealing performance is superior to that of the non-flange bearing. Because the bearings are flanged, the installation becomes easier.

ISUTAMI has been committed to the research and development of RFD round flange disc harrow bearings for years, and simulates the actual operating environment to verify the performance of the bearings, continuously improve to provide a complete range of round flange type disc harrow bearings in various environments. We can also produce conventional and unconventional flange disc harrow bearings according to the customer's specific size, materials and other requirements.
