FAQS

QWhat is angular contact ball bearings?

AAn angular contact bearing is a type of specialty ball bearing used in many manufacturing and industrial applications. This relatively small device is designed to support a greater range of forces than a standard bearing, and to work within even the most precisely engineered machines and equipment. Angular Contact Ball Bearings. Angular contact bearings from Grainger can support combined loads simultaneously in radial and axial directions. Use them for high-speed, high-precision applications, such as turbines and dentistry equipment, where dual-direction loads are present.

QWhat is Plain Bearings?

APlain bearings are used in many industries and across many applications where there is a need to cost-efficiently and reliably meet the challenge of oscillating movements and possible misalignment. From mining and construction equipment, farm and forestry machinery, all the way to forklift trucks and solar power equipment. The use of bearings, simplistic as they may have been then, dates back to at least the ancient Egyptians, and perhaps even predated the invention of the wheel. Today bearings can be found wherever there is relative motion between two surfaces, which includes virtually everything from household appliances to industrial machinery.

QWhat is Cylindrical roller bearings?

ACylindrical roller bearings have a high radial load capacity because the rollers and raceway are in linear contact, and they are suitable for applications that provide heavy radial and impact loads. A cage-guided cylindrical roller bearing helps keep the rolling elements in place, which becomes more crucial as loads get heavier. A cylindrical roller bearing can support light-thrust movement, with the double-row type also able to support axial loads in both directions.

QWhat is deep groove ball bearings?

ADeep Groove ball bearings are the most popular of all the ball bearing types because they are available in a wide variety of seal, shield and snap-ring arrangements.The bearing ring grooves are circular arcs made slightly larger than the radius of the ball. The balls make point contact with the raceways (elliptical contact when loaded). Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
