Functionality and Types of Heavy Duty Bearings
Bearings allow rotation or linear motion and reduce friction between two moving parts. These highly engineered, precision-built components enable machines to move at high speeds and carry remarkable loads with ease and efficiency.
Building structures that improve the quality of life for people and businesses requires a range of processes from land preparation to building design and development. A range of heavy equipment is needed to realize these achievements. Here are common bearing types found in construction and heavy equipment applications.
Spherical Sliding Bearings: These bearings are heavy-duty and high-performance machines. Also called spherical plane bearings or spherical ball bush bearings, they have an inner ring with a spherical convex outer surface and an outer ring with a spherical concave inner surface. This design makes them particularly suitable for bearing arrangements where alignment between shaft and housing is required or where oscillating or repetitive tilting motions occur at relatively slow sliding speeds.
Tapered Roller Bearings: This precision bearing offers high reliability and long service life and is perfect for supporting simultaneous radial and axial loads. Tapered roller bearings have a cup and cone assembly. The cup contains the outer ring while the cone assembly consists of an inner ring, rollers and cage. This bearing structure accommodates combined loads and provides low friction during operation.
Spherical Roller Bearings: These bearings are excellent for heavy radial and axial loads in applications prone to misalignment or shaft deflections. Spherical Roller Bearings are self-aligning with barrel-shaped rollers placed between an inner ring with two raceways and an outer ring with one spherical raceway. They provide greater fatigue strength, increased wear resistance and high protection against shock and acceleration.
Cylindrical Roller Bearings: This special roller bearing has a relatively high radial load capacity and is suitable for high speed applications. Cylindrical roller bearings are available in sealed or split designs. In sealed bearings, the rollers provide lubricant retention and protection against contaminants, water and dust. Split bearings are designed for hard-to-reach arrangements as they make maintenance and replacement easy.
Choosing Your Bearing
Bearings are essential to obtain consistent, long-term performance from heavy equipment used on construction sites. It reduces friction, allowing parts to move more smoothly and surfaces to wear less quickly. There are many things to consider when choosing the right bearing for your application.
