Product introduction

Square hole bearings are single row radial spherical ball bearings, which have self-aligning properties, can withstand large loads, and can be used in harsh cracking environments. Most square hole bearings have a full ball structure without retainers inside, which can withstand large loads; External square or hexagonal holes, capable of withstanding large torque loads; Outer diameter spherical surface, good centering performance, easy to install and disassemble bearings; Double layer contact sealing and dust-proof on both ends. The inner edge is a rolled edge steel skeleton three-layer rubber inner lip large interference contact sealing ring, and the middle is a dust-proof cover that matches the outer ring groove. The outer edge is a hole with an elastic retaining ring tightly pressing the dust-proof cover, which can effectively prevent the loss of lubricating grease inside the bearing and block the entry of soil, sand and water outside the bearing. The sealing performance is very good. Square hole bearings are generally full ball without retainers, but nylon retainers or corrugated iron retainers are also used. Square hole bearings are mainly used in situations where they can withstand large radial loads, high rotational torque, low speeds, and poor working environments. They are widely used in agricultural machinery, civil machinery parts, and other equipment. There are several types of square hole bearings, including closed full ball bearings without retainers or corrugated iron retainers, widened and thickened inner and outer rings, and square hole bearings with and without oil holes. The specifications are as follows: F-series bearings 39602/F29 (full ball), 39602/F29X2 (full ball, widened inner or outer ring), 39602/F33 (full ball), 39602/F33X2 (full ball, widened inner or outer ring), 39602/F41 (full ball).
