SKF Needle Roller Bearing 12 mm Inside Diameter 18 mm Outside Diameter Open End Type Sheet Steel Cage HK 1212

SKF HK 1212 is a needle roller bearing designed for precision radial load support where space constraints demand a compact bearing solution. It features a 12 mm inside diameter, 18 mm outside diameter, and a 12 mm race width, making it ideal for high-speed and high-load industrial applications.

The bearing is of open end type, allowing free circulation of oil or grease within clean operational environments while preventing lubricant contamination. Equipped with a sheet steel cage, this needle bearing offers excellent strength-to-weight ratio essential for dynamic machinery use.

With a static load rating of 7.35 kN and a dynamic load rating of 6.27 kN, the HK 1212 can sustain heavy loads reliably. It supports a maximum speed of 20,000 rpm when oiled and 14,000 rpm when greased, making it suitable for demanding mechanical systems. The bearing has a single row of rollers with a bore type that is parallel, ensuring precise fitment.

Applications include robotics systems, agricultural farming equipment, and construction machinery, where durability and compactness are critical. For best performance, shafts must be hardened and ground to suitable raceway tolerances or paired with an inner ring if shafts cannot be hardened.

Open end design allows effective lubricant circulation. Sheet steel cage balances strength and light weight. High load capacity for static and dynamic conditions. High maximum operating speeds with oil and grease lubrication.

Single row needle bearing for compact radial load handling. Applicable in robotics, farming, and construction machinery. Requires precise shaft preparation or use with an inner ring.
