Single Row Super-Precision Cylindrical Roller Bearings N 1008 KPHA/SP

Single Row Super-Precision Cylindrical Roller Bearings N 1008 KPHA/SP

The N 1008 KPHA/SP is a single-row cylindrical roller bearing with a 40mm bore and 68mm outer diameter, crafted from high-quality chrome steel. It handles combined loads up to 5242 lbf and reaches speeds of 36000 RPM, making it suitable for high-performance applications.

Its PEEK cage, centred on the outer ring, ensures smooth operation and durability. The open design allows for easy lubrication with grease or oil, and it operates efficiently in temperatures from -30°C to 110°C.

This bearing features a tapered bore (1:12 ratio) for secure fitting and can accommodate axial displacement up to 2mm. It’s interchangeable with SKF bearings, offering a reliable replacement option.

Ideal for precision machinery like spindles or gearboxes where high speeds and radial loads are common. Weighing just 0.19kg, it’s lightweight yet robust. Compliant with RoHS and REACH standards for safe use.
