Product Description

What this part is

SKF NU 1008 MP single-row cylindrical roller bearing. Bore Diameter: 40 mm. Outside Diameter: 68 mm. Overall Width: 15 mm. Number Of Rows: 1. Rolling Elements: Cylindrical Roller. Bore Type: Cylindrical. Cage Material: Machined brass. Closure Type: Open. Bearing Material: Bearing steel. Expansion Type: Non-locating. Series: NU 10. Base Number: NU 1008.

Decoding the designation

NU is the cylindrical roller design with two integral ribs on the outer ring and a plain, ribless inner ring. 1008 is the 10 extra-light dimension series at a 40 mm bore. M is a machined brass cage. Written as NU1008MP, NU 1008 MP and NU1008.

What these specs mean in practice

Dynamic Load Rating: 28,500 N. Static Load Rating: 26,000 N. Reference Speed: 12,000 rpm. Limiting Speed: 18,000 rpm. Line contact between roller and raceway is what gives a cylindrical roller several times the radial capacity of a ball bearing on the same envelope. The NU design lets the rollers run freely along the plain inner ring, so the shaft can grow axially inside the bearing by up to 2.4 mm as it warms — that is the non-locating position in a two-bearing shaft arrangement. A machined brass cage is strong, tolerant of high speed and shock, and works well with oil lubrication.
