SKF Needle Roller Bearing 19 mm ID, 27 mm OD, 20 mm Width, Carbon Chrome Steel Rollers NK 19/20

SKF NK 19/20 is a high-quality needle roller bearing designed with a 19 mm inside diameter, 27 mm outside diameter, and 20 mm race width. This bearing is engineered for heavy radial loads and high-speed operation, making it suitable for industrial, automotive, agricultural, and construction equipment applications.

The rollers are manufactured from carbon chrome steel, offering excellent wear resistance and corrosion protection. The bearing includes a reinforced polyamide 66 cage which reduces friction and improves lubricant flow, enhancing operational efficiency and service life.

SKF NK 19/20 bearings have a static load rating of 25.5 kN and a dynamic load rating of 16.5 kN, supporting robust load capacities. It operates at limiting speeds up to 24,000 rpm, with maximum speeds of 20,000 rpm when oil-lubricated and 14,000 rpm when grease-lubricated, suitable for very high-speed applications.

The bearing features a parallel bore type and an open end design, allowing easy installation and maintenance. It is constructed to follow strict international standards such as ISO 5753:1991, ISO 492:1994, ISO 14001, ISO 582:1995, DIN 17 230:1980, ISO 199:1997, and ISO 1000:1992, ensuring quality and reliability.

Additional design highlights include an outer ring with an annular groove for snap ring retention and axial positioning flanges for secure mounting. One of the major advantages of this needle Roller Bearing is its ability to use the mating surface as the inner raceway if the shaft is hardened and ground, eliminating the need for a separate inner ring and permitting the use of larger shaft diameters.

These bearings are originally manufactured in Slovakia, reflecting high production standards. They find application across sectors such as vehicle manufacturing, agricultural machinery production, power tools, and construction equipment, providing dependable performance under demanding conditions.
