Split Pillow Block Bearings
Pillow bock mount manufactured with a split plain bearing.
Shaft Size (Bore ID)
“Shaft size” is the measurement of shaft for your application. It can also be similar to the measurement of the “Bore” or “Inside Diameter” of your bearing. A slightly loose shaft fit is desirable for most applications.
For linkages and rod ends, shafts are not typically used but it refers to the measurement of the bore ID whether you are using a bolt or screw through the inside diameter of your rod end. See image below.
Bronze bearings are oil impregnated with SAE30-Non-Detergent oil. This results in a quiet operation, longer-life span and reduces the amount of dirt and dust that can get caught between the bore and shaft. You can find bronze bearings in many applications including lawn mowers, solar panels, food machinery and lawn tractor attachments.
Iron bearings have similar benefits as our bronze bearings and they are oil impregnated with SAE30-Non-Detergent oil as well. Having an oil-impregnated bearing allows for a longer-life span and quiet operation. Sintered iron bearings are best suited for a low load. Common applications include lawn tractors, solar trackers, lawn and garden equipment, packaging machinery and more.
Plastic nylon bearings are able to endure extreme temperatures, heavy loads and high speeds. They have a high wear resistance and can reduce costs. The main benefit of plastic bearings is that they are suitable for wash-down and sterile applications and are resistant to both salt water and harsh chemicals. Water can act as a lubricant for plastic bearings, which is a huge advantage as most bearings are unable to function, let alone excel in a damp or wet environment. Common applications include food production equipment and machinery, health care equipment and lawn and garden equipment.
Cast iron bearings are an inexpensive choice for applications utilizing low speed and high loads. Benefits of cast iron include gall-resistance and high heat tolerance. They can also be run dry due to the presence of graphite that acts as a lubricant. Common applications include heavy duty equipment machinery, agriculture equipment, combines and more.
Wood bearings are tolerant of dirt and good for high shaft rotation; they are also resistant to wet conditions and are used when the equipment is fully submerged; such as in paddle boats and other aquatic machinery. Wood bearings are also resistant to acids, such as those that are found in animal manure. This resistance leads to wood bearings being used in agricultural means, such as manure spreaders and other applications. Wood bearings are vacuum impregnated with oil or wax that leads to a low coefficient of friction and helps to seal the wood.
This bearing material type is a steel material with a chrome plating. Its aesthetic appearance is not the only benefit it has. Other benefits include a smooth operation, reduced end-play and is wear-resistant. Common applications include lawn mowers, light-vehicles, fitness equipment and more.
