Disc Bearings Square Bore Flanged
ISUTAMI FD square flange disc harrow bearing is a commonly used agricultural machinery bearing. It is usually installed in a disc harrow and is also an important spare part in agricultural machinery. The bearing is mainly composed of a ball bearing and dust-proof seals. The ball is made of bearing steel and is mounted in a cage to connect the inner and outer rings. Disc harrow bearings must be able to meet long-term operating requirements in dusty, humid environments, and can withstand large loads in the radial and axial directions, which is a requirement for arable land operations, too. The ISUTAMI disc harrow bearing has a multi-lip contact sealing structure to keep from dust; the material of bearing contains chromium, which can promote the hardening of the surface and enhances the bearing load capacity. The surface of the product is also treated with anti-corrosion. All SFD square flange disc harrow bearings are shown in English units(inches). The outer ring of this series has a round flange located in the middle of the bearing. Four mounting holes are evenly distributed over the flange for fixing and installing the bearing in the disc harrow.

Disc Bearings Square Bore Flanged Feature

SFD square flange disc harrow bearing inner bore is divided into two types: circular and square. The mounting holes on the flange are also divided into two types: circular and square. The inner rings of the bearings type 2 and type 4 are circular, and the diameter (A/d) ranges from 1.27'' to 2.188''. The length of the bearing (Bi) ranges from 1.685'' to 2.188'', and the hole spacing (D) between the two positions is 5'' or 5.5'' (especially FD212K51-60RD is 5.63''), the round hole of type 2 The hole diameter (E) is 0.531'' (especially FD212K51-60RD is 6.4''), the square hole length (G) of model 4 is 0.687'', and the diameter of the bearing body (B, except the flange) is 3.865'' or 4.491''. (especially FD212K51-60RD is 5''), using the equation of 3-6 lip seals; the model 3 bearing is with a square inner hole, and the diameter (A/d) is 1.18''-2''. The length of the bearing (Bi) is 1.685''-5.5'', the hole spacing (D) at the two positions is 5'' or 5.5'', and the square hole length (G) on the flange is 0.687'' ( especially FD209K51-1-1/4SQ is 3.865''), bearing body diameter (B, except flange) is 1.63''-4.491'', with 3 or 5 lip contact sealing structure, compared to non-flange disc harrow bearing, its sealing performance is better. Because the bearings are flanged, the installation process is quicker and easier.

ISUTAMI has long been committed to the R&D work of the SFD bearings for years, and we simulate the actual operating environment to verify the performance of the bearing. With continuously improving, we provide different specifications of flange square disc harrow bearings. We also produce conventional and unconventional flange disc harrow bearings according to the customer's requests.
