Spyraflo BFM-750-P 2-Bolt Hole, Steel Flange with a 3/4 inch Inner-Diameter, Self-Aligning, High Performance PTFE Impregnated Bronze Bearing
This Spyraflo self-aligning PTFE-impregnated bronze bearing with steel flange and two bolt holes is designed for mounting onto bearing surfaces perpendicular to the shaft axis. The flange is made of steel for strength and resistance to shock. The bronze plain bearing insert in the housing supports heavy loads, moderate speeds, and rotational, oscillatory, and linear motion. It is bonded to a steel backing for rigidity and a high load carrying capacity, and is impregnated with a polytetrafluoroethylene (PTFE) lubricant to reduce friction for applications that require slow speeds and frequent starts and stops. The lubricant remains in the pores of the bearing to provide lubricant from the bearing to the shaft during operation. The bearing resists glycols, alcohol, water, and mineral oils and is particularly suited for shock loads and applications with high levels of dirt and dust. The bearing insert is self-clinched in the steel flange for a secure fit and is replaceable. The bearing insert is self-aligning and compensates for +/- 5 degrees of static misalignment. This plain bearing has a maximum load value of 8,000 psi (pounds per square inch), a maximum velocity value of 400 fpm (surface feet per minute), and a maximum load-at-velocity (PV) value of 50,000, and operates at temperatures ranging from -40 to 280 degrees F (-40 to 137 degrees C). Designed with a regular straight bore, this bearing fits to conventional cylindrical shafts. Plain flanged bearings are for use in various applications such as heavy-lifting equipment, pumps, aircraft, and motors, among others.
Mounted bearings combine a bearing mounted inside a housing unit. The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads. Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris. Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers.
