Specialty rotary bearings are specialized or proprietary rotary products and accessories related to roller bearings. There are different types of specialty rotary bearings available including a roller thrust bearing, ball thrust bearing, tapered roller bearing, and cylindrical bearings. Specialty rotary bearings are used in ship line shafts, crankshafts, and in rolling mills to move the roller.
Specialty rotary bearings function in a variety of ways. Specialty rotary bearings utilize a cylindrical roller that handles large loads because the inner and outer race is in contact to form a line rather than a point, which helps it to divide the load. A tapered roller bearing consists of four inter-dependent components: the inner ring, outer ring, rolling elements, and roller retainer. A tapered roller bearing is capable of supporting large thrust and radial loads. A tapered roller bearing is used in a central hub bearing for automobile wheels. A needle roller bearing uses a roller bearing that has very small diameter and thus it can fit into tight or small spaces. A needle roller bearing is used in precision shafting in aircraft for the wing flap. A spherical roller bearing is self-aligning and is available with bore sizes of 25mm and greater. A spherical roller bearing provides consistent performance even with very high speed or critical stress. A spherical roller bearing is used in rudder shaft and grinding machines. A conveyor roller bearing provides maximum load capacity and high quality. A conveyor roller bearing is utilized in tough situations where large loads are to be conveyed. A taper roller bearing is available in many sizes and is most popularly used in gear construction, vehicle manufacturing, and rolling mills. A cylindrical roller bearing is also widely used in many industries due to their high speed and increased load carrying capacity. A cylindrical roller bearing provides economical use where the thermal expansion of housing or shaft can be compensated. Rotary bearing design is based on mathematics and geometry that provides linear motion. A cylindrical roller bearing has ¼ inch rotary probe, and independent linear and rotary probes. A rotary gearbox bearing can be used in jacks to provide friction. A linear rotary bearing offers longer life even at a high load, and smooth operation. A linear rotary bearing provides motion in a straight line for example it may be employed in drawers that have to be pulled. Specialty rotary bearings are generally constructed of carburized or case-hardened material which is characterized by a hardened surface (greater than 0.015 in. thick) and a soft core.
Specialty rotary bearings are required for many applications, from heavy-duty use in vehicle axles and machine shafts, to precision clock parts. Specialty rotary bearings can be used in conveyor belts, grinding machines, mining, and for power generation. Specialty rotary bearings and mostly self-lubricating and should provide smooth operation.
