Radial spherical plain bearings

Radial spherical plain bearings have an inner ring with a sphered convex outside diameter and an outer ring with a correspondingly sphered but concave inside surface. Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated, or where oscillating or recurrent tilting or slewing movements must be possible at relatively slow sliding speeds, often accompanied with heavy loads.

Spherical plain bearings are manufactured in a wide variety of materials and are designed to offer bearing solutions in almost any operating environment. FGB Bearings offers a complete line of spherical bearings available in inch and metric. These High-Quality Spherical Plain Bearings are suitable for heavy-duty, off-highway vehicles, agricultural equipment, construction and mining and logging equipment, packaging and textile equipment, and robotics. The plain bearings come in standard industrial bore sizes from 0.5" to 12" inches, as well as metric sizes from as small as 4 to 600 mm. Custom sizes can also be ordered.
Design Attributes
- Rings manufactured from hardened steel help deliver consistent, reliable performance.
- Phosphate-treated rings coated with molybdenum disulfide (MoS2) minimize friction of contacting surfaces.
- Simplified housing and shaft designs reduce installation time.
Applications
- A-frames, dump cylinders, front and rear struts, and steering cylinders for mining trucks
- Equalizer track bars, lift and tilt cylinders, push blades, trunnion balls and ripper blades for bulldozers
- Articulated joint upper and lower steering cylinders and boom and bucket cylinders for wheel loaders
- Stick and bucket cylinders for hydraulic excavators
- Additional applications for space shuttles, heavy movable structures and miscellaneous vehicles
Key words:
- bearings
